The 6th International Workshop on Micro and Nanotechnologies for Power Generation and Energy Conversion Applications (PowerMEMS 2006)
Energy is a sector of paramount importance over the coming decades if we are to ensure sustainable development that respects our environment. The research and development of novel approaches to convert available energy into usable forms using micro and nanotechnologies can contribute towards this goal and meet the growing need for power in small scale portable applications. The dominant power sources for handheld and other portable electronics are currently primary and rechargeable batteries. Their limited energy density and adverse effects on the environment upon disposal suggest that alternative approaches need to be explored. This special issue will showcase some of the leading work in this area, initially presented at PowerMEMS 2006, the 6th International Workshop on Micro and Nanotechnologies for Power Generation and Energy Conversion Applications. Power MEMS are defined as microsystems for electrical power generation and other energy conversion applications, including propulsion and cooling. The range of power MEMS technologies includes micro thermodynamic machines, such as microturbines, miniature internal combustion engines and micro-coolers; solid-state direct energy conversion, such as thermoelectric and photovoltaic microstructures; micro electrochemical devices, such as micro fuel cells and nanostructure batteries; vibration energy harvesting devices, such as piezoelectric, magnetic or electrostatic micro generators, as well as micro thrusters and rocket engines for propulsion. These can either be driven by scavenging thermal, mechanical or solar energy from the environment, or from a stored energy source, such as chemical fuel or radioactive material. The unique scope leads to unique challenges in the development of power MEMS, ranging from the integration of novel materials to the efficient small scale implementation of energy conversion principles. In this special issue, Mitcheson et al provide a comparative assessment of three inertial vibration energy harvesting approaches. Technologies and approaches for micro heat engines are shared, ranging from a complete microsystem for thermal energy harvesting (Cho et al) to core bearing and microturbomachinery technologies for rotating micro heat engines (Waits et al, Nakajima et al). Electrochemical microsystems are also presented, based on methanol as fuel (Morse et al), as well as novel micro and nanofabrication approaches (Chu et al). Fuel cell microsystems with integrated hydrogen generation approaches are also investigated by Peterson et al and Varady et al, illustrating the benefits and challenges of miniaturizing complete power sources. Finally, biological micro fuel cells that leverage the principles found in nature are presented, in contrast to chemical fuel cells (Chen et al, Morishima et al). We hope that this work will inspire others to pursue innovative research and development activities in the area of power MEMS, and consequently contribute to addressing our energy challenges for the 21st century.

The 'Mine/Yours' method of international comparisons of carbon emissions
In previous work (Schipper, Unander & Lilliu 1999), we summarized a new method for comparing energy use and carbon emissions among various countries. We call this the ''Mine/Yours'' comparison. In this paper, we provide details of the comparisons methodology, and carry out the comparison on a number of IEA countries. We calculate the average energy intensities I for a sample of countries (''yours'') and multiply them by structural parameters S for a particular country (''mine''). Comparing the results with the actual energy use of the country in question gives us an estimate of how much energy that country would use with average intensities but with its own structural conditions. The converse can be calculated as well, that is, average structure and own intensities. Emissions can be introduced through the F (fuel mix) term. These calculations show where differences in the components of emissions lead to large gaps among countries, and where those differences are not important. We show which components cause the largest variance in emissions by sector. In households, home size, average winter climate, and energy intensity appear to be the most important differentiating characteristics for space heating. For other residential energy uses the mix of fuels used to generate electricity (utility mix) is most important. Because some of the differences are ''built in'' - geography, climate, natural resources endowment - we conclude by questioning whether uniform emissions reductions targets make sense. Indeed, the ''Mine/Yours'' tool provides a valuable guide to important ways in which emissions may or may not be flexible.

Microelectromechanical (MEM) thermal actuator
Microelectromechanical (MEM) buckling beam thermal actuators are disclosed wherein the buckling direction of a beam is constrained to a desired direction of actuation, which can be in-plane or out-of-plane with respect to a support substrate. The actuators comprise as-fabricated, linear beams of uniform cross section supported above the substrate by supports which rigidly attach a beam to the substrate. The beams can be heated by methods including the passage of an electrical current through them. The buckling direction of an initially straight beam upon heating and expansion is controlled by incorporating one or more directional constraints attached to the substrate and proximal to the mid-point of the beam. In the event that the beam initially buckles in an undesired direction, deformation of the beam induced by contact with a directional constraint generates an opposing force to re-direct the buckling beam into the desired direction. The displacement and force generated by the movement of the buckling beam can be harnessed to perform useful work, such as closing contacts in an electrical switch.

Design of Surface micromachined Compliant MEMS
The consideration of compliant mechanisms as Microelectromechanical Systems (MEMS) is the focus of this research endeavor. MEMS are micron to millimeter devices that combine electrical, mechanical, and information processing capabilities on the same device. These MEMS need some mechanical motion or parts that move relative to each other. This relative motion, using multiple parts, is not desired because of the assembly requirement and the friction introduced. Compliant devices limits or eliminates friction and the need for multi-component assembly. Compliant devices improve designs by creating single piece mechanisms. The purpose of this research is to validate surface micromachining as a viable fabrication process for compliant MEMS designs. Specifically, this research has sought to fabricate a micro-compliant gripper and a micro-compliant clamp to illustrate the process. While other researchers have created compliant MEMS, most have used comb-drive actuation methods and bulk micromachining processes. This research focuses on fully-compliant devices that use device flexibility for motion and actuation. Validation of these compliant MEMS is achieved by structural optimization of device design and functional performance testing. This research contributes to the ongoing research in MEMS by evaluating the potential of using surface micromachining as a process for fabricating compliant micro-mechanisms.

Combined photonics and MEMs function demonstration
The authors have recently demonstrated two prototypes where photonics and microelectromechanical system (MEMs) technologies have been integrated to show proof-of-principle functionality for weapon surety functions. These activities are part of a program which is exploring the miniaturization of electromechanical components for making weapon systems safer. Such miniaturization can lead to a low-cost, small, high-performance ``systems-on-a-chip``, and have many applications ranging from advanced military systems to large-volume commercial markets like automobiles, rf or land-based communications networks and equipment, or commercial electronics. One of the key challenges in realization of the microsystem is integration of several technologies including digital electronics; analog and rf electronics, optoelectronics (light emitting and detecting devices and circuits), sensors and actuators, and advanced packaging technologies. In this work the authors describe efforts in integrating MEMs and photonic functions and the fabrication constraints on both system components. Here, they discuss two examples of integration of MEMs and a photonic device. In the first instance, a MEMs locking device pin is driven by a voltage generated by photovoltaic cells connected in series, which are driven by a laser. In the second case, a VCSEL emitting at 1.06 {micro}m is packaged together with a metallized MEMs shutter. By appropriate alignment to the opening in the shutter, the VCSEL is turned on and off by the movement of the Si chopper wheel.

High-speed, sub-pull-in voltage MEMS switching.
We have proposed and demonstrated MEMS switching devices that take advantage of the dynamic behavior of the MEMS devices to provide lower voltage actuation and higher switching speeds. We have explored the theory behind these switching techniques and have demonstrated these techniques in a range of devices including MEMS micromirror devices and in-plane parallel plate MEMS switches. In both devices we have demonstrated switching speeds under one microsecond which has essentially been a firm limit in MEMS switching. We also developed low-loss silicon waveguide technology and the ability to incorporate high-permittivity dielectric materials with MEMS. The successful development of these technologies have generated a number of new projects and have increased both the MEMS switching and optics capabilities of Sandia National Laboratories.

Pre-release plastic packaging of MEMS and IMEMS devices
A method is disclosed for pre-release plastic packaging of MEMS and IMEMS devices. The method can include encapsulating the MEMS device in a transfer molded plastic package. Next, a perforation can be made in the package to provide access to the MEMS elements. The non-ablative material removal process can include wet etching, dry etching, mechanical machining, water jet cutting, and ultrasonic machining, or any combination thereof. Finally, the MEMS elements can be released by using either a wet etching or dry plasma etching process. The MEMS elements can be protected with a parylene protective coating. After releasing the MEMS elements, an anti-stiction coating can be applied. The perforating step can be applied to both sides of the device or package. A cover lid can be attached to the face of the package after releasing any MEMS elements. The cover lid can include a window for providing optical access. The method can be applied to any plastic packaged microelectronic device that requires access to the environment, including chemical, pressure, or temperature-sensitive microsensors; CCD chips, photocells, laser diodes, VCSEL's, and UV-EPROMS. The present method places the high-risk packaging steps ahead of the release of the fragile portions of the device. It also provides protection for the die in shipment between the molding house and the house that will release the MEMS elements and subsequently treat the surfaces.

Thin Silicon MEMS Contact-Stress Sensor
This thin, MEMS contact-stress (CS) sensor continuously and accurately measures time-varying, solid interface loads in embedded systems over tens of thousands of load cycles. Unlike all other interface load sensors, the CS sensor is extremely thin (< 150 {micro}m), provides accurate, high-speed measurements, and exhibits good stability over time with no loss of calibration with load cycling. The silicon CS sensor, 5 mm{sup 2} and 65 {micro}m thick, has piezoresistive traces doped within a load-sensitive diaphragm. The novel package utilizes several layers of flexible polyimide to mechanically and electrically isolate the sensor from the environment, transmit normal applied loads to the diaphragm, and maintain uniform thickness. The CS sensors have a highly linear output in the load range tested (0-2.4 MPa) with an average accuracy of {+-} 1.5%.

MEMS Reliability: Infrastructure, Test Structures, Experiments, and Failure Modes
The burgeoning new technology of Micro-Electro-Mechanical Systems (MEMS) shows great promise in the weapons arena. We can now conceive of micro-gyros, micro-surety systems, and micro-navigators that are extremely small and inexpensive. Do we want to use this new technology in critical applications such as nuclear weapons? This question drove us to understand the reliability and failure mechanisms of silicon surface-micromachined MEMS. Development of a testing infrastructure was a crucial step to perform reliability experiments on MEMS devices and will be reported here. In addition, reliability test structures have been designed and characterized. Many experiments were performed to investigate failure modes and specifically those in different environments (humidity, temperature, shock, vibration, and storage). A predictive reliability model for wear of rubbing surfaces in microengines was developed. The root causes of failure for operating and non-operating MEMS are discussed. The major failure mechanism for operating MEMS was wear of the polysilicon rubbing surfaces. Reliability design rules for future MEMS devices are established.

Integrated optical MEMS using through-wafer vias and bump-bonding.
This LDRD began as a three year program to integrate through-wafer vias, micro-mirrors and control electronics with high-voltage capability to yield a 64 by 64 array of individually controllable micro-mirrors on 125 or 250 micron pitch with piston, tip and tilt movement. The effort was a mix of R&D and application. Care was taken to create SUMMiT{trademark} (Sandia's ultraplanar, multilevel MEMS technology) compatible via and mirror processes, and the ultimate goal was to mate this MEMS fabrication product to a complementary metal-oxide semiconductor (CMOS) electronics substrate. Significant progress was made on the via and mirror fabrication and design, the attach process development as well as the electronics high voltage (30 volt) and control designs. After approximately 22 months, the program was ready to proceed with fabrication and integration of the electronics, final mirror array, and through wafer vias to create a high resolution OMEMS array with individual mirror electronic control. At this point, however, mission alignment and budget constraints reduced the last year program funding and redirected the program to help support the through-silicon via work in the Hyper-Temporal Sensors (HTS) Grand Challenge (GC) LDRD. Several months of investigation and discussion with the HTS team resulted in a revised plan for the remaining 10 months of the program. We planned to build a capability in finer-pitched via fabrication on thinned substrates along with metallization schemes and bonding techniques for very large arrays of high density interconnects (up to 2000 x 2000 vias). Through this program, Sandia was able to build capability in several different conductive through wafer via processes using internal and external resources, MEMS mirror design and fabrication, various bonding techniques for arrayed substrates, and arrayed electronics control design with high voltage capability.

Novel Fabrication and Simple Hybridization of Exotic Material MEMS
Work in materials other than silicon for MEMS applications has typically been restricted to metals and metal oxides instead of more ''exotic'' semiconductors. However, group III-V and II-VI semiconductors form a very important and versatile collection of material and electronic parameters available to the MEMS and MOEMS designer. With these materials, not only are the traditional mechanical material variables (thermal conductivity, thermal expansion, Young's modulus, etc.) available, but also chemical constituents can be varied in ternary and quaternary materials. This flexibility can be extremely important for both friction and chemical compatibility issues for MEMS. In addition, the ability to continually vary the bandgap energy can be particularly useful for many electronics and infrared detection applications. However, there are two major obstacles associated with alternate semiconductor material MEMS. The first issue is the actual fabrication of non-silicon devices and the second impediment is communicating with these novel devices. We will describe an essentially material independent fabrication method that is amenable to most group III-V and II-VI semiconductors. This technique uses a combination of non-traditional direct write precision fabrication processes such as diamond turning, ion milling, laser ablation, etc. This type of deterministic fabrication approach lends itself to an almost trivial assembly process. We will also describe in detail the mechanical, electrical, and optical self-aligning hybridization technique used for these alternate-material MEMS.

Acoustic resonance for nonmetallic mine detection
The feasibility of acoustic resonance for detection of plastic mines was investigated by researchers at the Oak Ridge National Laboratory`s Instrumentation and Controls Division under an internally funded program. The data reported in this paper suggest that acoustic resonance is not a practical method for mine detection. Representative small plastic anti-personnel mines were tested, and were found to not exhibit detectable acoustic resonances. Also, non-metal objects known to have strong acoustic resonances were tested with a variety of excitation techniques, and no practical non-contact method of exciting a consistently detectable resonance in a buried object was discovered. Some of the experimental data developed in this work may be useful to other researchers seeking a method to detect buried plastic mines. A number of excitation methods and their pitfalls are discussed. Excitation methods that were investigated include swept acoustic, chopped acoustic, wavelet acoustic, and mechanical shaking. Under very contrived conditions, a weak response that could be attributed to acoustic resonance was observed, but it does not appear to be practical as a mine detection feature. Transfer properties of soil were investigated. Impulse responses of several representative plastic mines were investigated. Acoustic leakage coupling, and its implications as a disruptive mechanism were investigated.

Atomic Calligraphy: The Direct Writing of Nanoscale Structures using MEMS
We present a micro-electromechanical system (MEMS) based method for the resist free patterning of nano-structures. Using a focused ion beam (FIB) to customize larger MEMS machines, we fabricate apertures as small as 50 nm on plates that can be moved with nanometer precision over an area greater than 20x20 {\\mu}m^2. Depositing thermally evaporated gold atoms though the apertures while moving the plate results in the deposition of nanoscale metal patterns. Adding a shutter only microns above the aperture, enables high speed control of not only where but also when atoms are deposited. Using a shutter, different sized apertures can be selectively opened and closed for nano-structure fabrication with features ranging from nano- to micrometers in scale. The ability to evaporate materials with high precision, and thereby fabricate circuits and structures in situ, enables new kinds of experiments based on the interactions of a small number of atoms and eventually even single atoms.

Uranium Mining and Enrichment
Overview Presentation » Uranium Mining and Enrichment Overview Presentation » Uranium Mining and Enrichment Uranium Mining and Enrichment Uranium is a radioactive element that occurs naturally in the earth's surface. Uranium is used as a fuel for nuclear reactors. Uranium-bearing ores are mined, and the uranium is processed to make reactor fuel. In nature, uranium atoms exist in several forms called isotopes - primarily uranium-238, or U-238, and uranium-235, or U-235. In a typical sample of natural uranium, most of the mass (99.3%) would consist of atoms of U-238, and a very small portion of the total mass (0.7%) would consist of atoms of U-235. Uranium Isotopes Isotopes of Uranium Using uranium as a fuel in the types of nuclear reactors common in the United States requires that the uranium be enriched so that the percentage of U-235 is increased, typically to 3 to 5%.

Mining the earth
Substances extracted from the earth - stone, iron, bronze - have been so critical to human development that historians name the ages of our past after them. But while scholars have carefully tracked human use of minerals, they have never accounted for the vast environmental damage incurred in mineral production. Few people would guess that a copper mining operation has removed a piece of Utah seven times the weight of all the material dug for the Panama Canal. Few would dream that mines and smelters take up to a tenth of all the energy used each year, or that the waste left by mining measures in the billions of tons - dwarfing the world's total accumulation of more familiar kinds of waste, such as municipal garbage. Indeed, more material is now stripped from the earth by mining than by all the natural erosion of the earth's rivers. The effects of mining operations on the environment are discussed under the following topics: minerals in the global economy, laying waste, at what cost cleaning up, and dipping out. It is concluded that in the long run, the most effective strategy for minimizing new damage is not merely to make mineral extraction cleaner, but to reduce the rich nations needs for virgin (non-recycled) minerals.

MEMS design rule checking: a batch approach for remote operation
This paper describes a design rule checking (DRC) tool developed as an aid for designing microelectromechanical structures (MEMS) using AutoCAD running on a Windows NT workstation. The application suite, MEMSdrc, consists of: a graphical user interface integrated into AutoCAD to invoke DRC, translation and interface software to communicate with a commercial IC layout design checking software package, and routines to interactively display and review the results. The user interface provides the capability to select a checking window area and specific DRC rules to be applied to the design. The MEMS structures, defined as 2D AutoCAD geometry are translated first into DXF format, then to GDSII format. A remote process transfers the files to a Unix workstation where Mentor Graphics ICverify is invoked to perform the layout design rule checks. Upon completion, the results are translated into DXF geometry and returned back to the Windows NT workstation to be overlaid onto the original design. A set of icons are provided for the user to interactively review the results inside of AutoCAD using a first/next/previous technique.

Uncooled IR photon detection using MEMS micro-structures
Generation of free carriers in a semiconductor gives rise to mechanical stress. Photo-induced stress phenomena in MEMS micro-structures can be used in the room temperature detection of infrared photons. Choice of the appropriate semiconductor material for the MEMS micro-structures determines the cutoff wavelength of the uncooled infrared photon detector. The authors have measured the deflection of silicon and indium antimonide micro-structures resulting from a photo-induced stress. The excess charge carriers responsible for the photo-induced stress were produced via photon irradiation from both a diode laser and a black body source. In the case of Si, the photo-induced stress is of opposite direction and about four times larger than the thermal stress. For indium antimonide the direction of stress is the same as due to thermal effects. The photo-induced stress can be distinguished from the thermal stress based on the cut-off wavelength, response speed, and perhaps the direction of the microstructure deflection.

Saving energy in mining
The struggle to reduce power costs is relentless in the world of mining. One of the most significant trends has been the use of electric instead of diesel power in such mining vehicles as large capacity dump trucks, hydraulic excavators, and articulated trucks. The hydraulic excavator, due to its selectivity, high breakout force, and maneuverability, has become increasingly popular as the loading unit in conventional shovel and truck operations. However, hydraulic shovels were originally only available as diesel powered units. Electric power for the prime mover is now offered as an option by most manufacturers. This is particularly cost effective with the larger machines. In surface mines, the transport of coal and overburden consumes the most energy. The application of such technology as in-pit crushers and conveyor systems are all aimed at reducing operating costs. A major development in reducing ventilation energy consumption is the Ventcon system based on the idea of distributing ventilation air more effectively around the mine. Ventcon controls the mine's fans and ventilation doors so that airflow is highest where most is required. The use of continuous haulage from the face to the surface is another energy-saving development. In many areas of Appalachia, United States, coal is cut by a continuous miner and hauled directly to the surface by a series of conveyors. The use of aluminum in cage and skip manufacturehas also been proven as an energy-saving technique. All-aluminum man cages are already in use. For the tougher application of hoisting coal, aluminum can be substituted for heavier materials in the construction of skips. In both cases, significant energy savings, and thus reduced hoisting costs, are the result. There is a power saving of more than 100 kilowatts (134 horsepower) for every one ton reduction of skip mass. The energy efficiencies of hydraulic rock drills are higher than pneumatic drills.

Integration of optoelectronics and MEMS by free-space micro-optics
This report represents the completion of a three-year Laboratory-Directed Research and Development (LDRD) program to investigate combining microelectromechanical systems (MEMS) with optoelectronic components as a means of realizing compact optomechanical subsystems. Some examples of possible applications are laser beam scanning, switching and routing and active focusing, spectral filtering or shattering of optical sources. The two technologies use dissimilar materials with significant compatibility problems for a common process line. This project emphasized a hybrid approach to integrating optoelectronics and MEMS. Significant progress was made in developing processing capabilities for adding optical function to MEMS components, such as metal mirror coatings and through-vias in the substrate. These processes were used to demonstrate two integration examples, a MEMS discriminator driven by laser illuminated photovoltaic cells and a MEMS shutter or chopper. Another major difficulty with direct integration is providing the optical path for the MEMS components to interact with the light. The authors explored using folded optical paths in a transparent substrate to provide the interconnection route between the components of the system. The components can be surface-mounted by flip-chip bonding to the substrate. Micro-optics can be fabricated into the substrate to reflect and refocus the light so that it can propagate from one device to another and them be directed out of the substrate into free space. The MEMS components do not require the development of transparent optics and can be completely compatible with the current 5-level polysilicon process. They report progress on a MEMS-based laser scanner using these concepts.
Ultrananocrystalline diamond films with optimized dielectric properties for advanced RF MEMS capacitive switches
An efficient deposition process is provided for fabricating reliable RF MEMS capacitive switches with multilayer ultrananocrystalline (UNCD) films for more rapid recovery, charging and discharging that is effective for more than a billion cycles of operation. Significantly, the deposition process is compatible for integration with CMOS electronics and thereby can provide monolithically integrated RF MEMS capacitive switches for use with CMOS electronic devices, such as for insertion into phase array antennas for radars and other RF communication systems.

Inertial sensing microelectromechanical (MEM) safe-arm device
Microelectromechanical (MEM) safe-arm devices comprise a substrate upon which a sense mass, that can contain an energetic material, is constrained to move along a pathway defined by a track disposed on the surface of the substrate. The pathway has a first end comprising a "safe" position and a second end comprising an "armed" position, whereat the second end the sense mass can be aligned proximal to energetic materials comprising the explosive train, within an explosive component. The sense mass can be confined in the safe position by a first latch, operable to release the sense mass by an acceleration acting in a direction substantially normal to the surface of the substrate. A second acceleration, acting in a direction substantially parallel to the surface of the substrate, can cause the sense mass to traverse the pathway from the safe position to the armed position.

Dust Grain-Size Distributions From MRN to MEM
Employing the Maximum Entropy Method algorithm, we fit interstellar extinction measurements which span the wavelength range 0.125-3 micron. We present a uniform set of MEM model fits, all using the same grain materials, optical constants and abundance constraints. In addition, we are taking advantage of improved UV and IR data and better estimates of the gas-to-dust ratio. The model fits cover the entire range of extinction properties that have been seen in the Galaxy and the Magellanic Clouds. The grain models employed for this presentation are the simplistic homogeneous spheres models (i.e., Mathis, Rumpl, & Nordsieck 1977) with two (graphite, silicate) or three (graphite, silicate, amorphous carbon) components. Though such usage is only a first step, the results do provide interesting insight into the use of grain size as a diagnostic of dust environment. We find that the SMC Bar extinction curve cannot be fit using carbon grains alone. This is a challenge to the recent observational result indicating little silicon depletion in the SMC.

10 - MEMS for harsh environment sensors in aerospace applications: selected case studies
Abstract: In this chapter we shall attempt to provide the reader with an understanding of what MEMS (micro-electromechanical systems) is and how it has become an enabling technology for some harsh environment aerospace applications, how it can contribute significantly to enhancing existing and future aerospace systems. We will explain what is meant by a harsh environment and how the engineer/scientist would need to accommodate his/her design to perform in this domain. Conveying this is perhaps best accomplished by presenting selected �case studies�, engineering examples of selected MEMS systems designed specifically for harsh environments in aerospace applications.

Surface mine reclamation for wildlife
This document presents a reclamation plan for use on surface coal mines in southern Appalachia. The plan has been implemented cooperatively by TVA and the FWS on a mine site in Campbell County, Tennessee. Included are suggestions for establishing groundcover and trees on the mine site, and for retaining surface water on mine sites. All techniques discussed are to benefit wildlife and to assist the operator in achieving bond release. Also included is a section on the costs of reclaiming the Campbell County study site to benefit forestry and wildlife. The costs of this project are compared to the costs of reclaiming a more traditional forestry (monoculture) option. The comparison showed the techniques at the study site to be less costly than those that would be associated with a forestry option. 11 references, 14 figures, 2 tables.

Treatment of acid mine wastewaters
Acid mine drainage often results from the oxidation sulfide minerals to form sulfuric acid. As a consequence, high concentrations of metals in the both the suspended and dissolved state result from the low pH water. This paper discusses several of the more common treatment methods for acid mine drainage including the use of chemical precipitation agents, pH correction agents, filtration methods, and biodegradation methods. Advanced treatment technologies are also briefly described and include microfiltration, reverse osmosis, ion exchange, and electrodialysis.

Semi autonomous mine detection system
CMMAD is a risk reduction effort for the AMDS program. As part of CMMAD, multiple instances of semi autonomous robotic mine detection systems were created. Each instance consists of a robotic vehicle equipped with sensors required for navigation and marking, a countermine sensors and a number of integrated software packages which provide for real time processing of the countermine sensor data as well as integrated control of the robotic vehicle, the sensor actuator and the sensor. These systems were used to investigate critical interest functions (CIF) related to countermine robotic systems. To address the autonomy CIF, the INL developed RIK was extended to allow for interaction with a mine sensor processing code (MSPC). In limited field testing this system performed well in detecting, marking and avoiding both AT and AP mines. Based on the results of the CMMAD investigation we conclude that autonomous robotic mine detection is feasible. In addition, CMMAD contributed critical technical advances with regard to sensing, data processing and sensor manipulation, which will advance the performance of future fieldable systems. As a result, no substantial technical barriers exist which preclude � from an autonomous robotic perspective � the rapid development and deployment of fieldable systems.

Longwall mining of thin seams
Thin seam operations pose a challenge to the ingenuity of mining engineers to overcome the factor of human inconvenience in the restricted environment and associated high cost production. Surprisingly, low seam longwalls in the Federal Republic of Germany in an average thickness of 35 in. and dipping less than 18/sup 0/ come close to achieving the average production rate of all German longwall operations. They are all plow faces, and a consistent production of 3300 tons per day and a productivity of 40 tons per man shift are reported from one of the thin seam longwalls. These results were attained by reliable high-capacity equipment and roof support by shields that can be collapsed to as low as 22 inches. Maximum mining height for plow operated faces lies at 31.5 inches. Technology for mechanized mining of flat lying coalbeds less than 31.5 inches in thickness without rock cutting is not available, and firmness of coal, undulation of the strata, coalbed thickness variation, and the necessity of cutting rock, particularly through faults, set limits to plow application. The in-web shearer can be used in firm coal to a minimum mining height of 40 inches, and a daily production of 1650 to 2200 tons is reported from a longwall in the Saar district of Germany equipped with such a shearer and shields. Numerous in-web shearers are employed in the United Kingdom; reports as to their success are contradictory. Also, experience in the United States, though limited, has been negative. The steady increase in output from single drum shearer faces in Pennsylvania is a remarkable achievement, and occasional record breaking peaks in production indicate the potential of such mining. Technology development for the future is discussed.

A domain adaptive stochastic collocation approach for analysis of MEMS under uncertainties
This work proposes a domain adaptive stochastic collocation approach for uncertainty quantification, suitable for effective handling of discontinuities or sharp variations in the random domain. The basic idea of the proposed methodology is to adaptively decompose the random domain into subdomains. Within each subdomain, a sparse grid interpolant is constructed using the classical Smolyak construction [S. Smolyak, Quadrature and interpolation formulas for tensor products of certain classes of functions, Soviet Math. Dokl. 4 (1963) 240-243], to approximate the stochastic solution locally. The adaptive strategy is governed by the hierarchical surpluses, which are computed as part of the interpolation procedure. These hierarchical surpluses then serve as an error indicator for each subdomain, and lead to subdivision whenever it becomes greater than a threshold value. The hierarchical surpluses also provide information about the more important dimensions, and accordingly the random elements can be split along those dimensions. The proposed adaptive approach is employed to quantify the effect of uncertainty in input parameters on the performance of micro-electromechanical systems (MEMS). Specifically, we study the effect of uncertain material properties and geometrical parameters on the pull-in behavior and actuation properties of a MEMS switch. Using the adaptive approach, we resolve the pull-in instability in MEMS switches. The results from the proposed approach are verified using Monte Carlo simulations and it is demonstrated that it computes the required statistics effectively.

Internal Tides
Abstract Internal tides are internal waves at tidal frequencies and are generated by interaction of the barotropic surface tide with bottom topography. Being dependent on ocean stratification and background currents, internal tides tend to be highly variable in time, sometimes almost erratic, yet in the open ocean the lowest mode can travel great distances across ocean basins while remaining phase-locked with the astronomical potential. Internal tides are an important energy source for ocean mixing.

Surface mining: soil, coal, and society
The book concentrates on the effects of surface mining of coal upon the utilization of another resource, soil. Possible planning and management strategies for land reclamation are studied and the problem of choosing the correct solution for a particular situation is considered taking the many factors into account. The goal of reconstructing soil after mining is to equal or exceed the productivity of pre-mine soils, with a change in landscape if necessary, with minimum disturbance to the local community.

FUEL CELLS � SOLID OXIDE FUEL CELLS | Internal and External Reformation
Three basic concepts of solid oxide fuel cell (SOFC) systems operating on hydrocarbon fuels, with external, internal, and partial prereforming, respectively, are presented and discussed. Internal reforming of methane is advantageously used for additional cooling of the SOFC stack, thus increasing system efficiency. Basic thermodynamics, catalysis, and kinetics of the methane steam reforming process are presented. Examples of SOFC stacks operating on internal reforming of methane and simulated partial prereforming of mine gas and natural gas are discussed. The latter is used to illustrate the effect of internal methane reforming on heat management in SOFC stacks.

LensMEM: A Gravitational Lens Inversion Algorithm Using the Maximum Entropy Method
We present a new algorithm for inverting poorly resolved gravitational lens systems using the maximum entropy method (MEM). We test the method with simulations and then apply it to an 8 GHz VLA map of the radio ring lens MG1654+134. We model the lens as a singular isothermal sphere embedded in an external shear field and find the critical radius of the lens is $b=0\\parcs9820$, the dimensionless shear is $\\gamma=0.0771$, and the position angle of the shear is $\\theta=100\\pdeg8$. These results are consistent with the results obtained by Kochanek (1995) using a complementary inversion algorithm based on Clean.

Mined land reclamation by biological reactivation
A mine reclamation technique, developed in Europe, restores land to full productivity within two years without topsoil replacement. The method deliberately reestablishes within one year following mining, the required biological balance between microbes, enzymes, and trace elements in the rock spoil rather than waiting five or more years for natural processes to restore balance. The technique is called Biological Reactivation (BR). This paper discusses the feasibility of BR reclamation after surface mining operations in the US. Staff of the Ohio Mining and Mineral Resources Research Institute completed an OSM-sponsored research project on BR in which physical and chemical tests characterized 140 spoil samples obtained from 10 surface mining operations. Test results indicated that Biological Reactivation technology could be effectively applied, at least in the test areas sampled within Appalachia. Preliminary estimates make clear that the new technique reduces reclamation costs on prime farmland by approximately 95% compared to topsoil segregation and replacement methods.

Testing terrorism theory with data mining
This research demonstrates the application of multiple data mining techniques to test theories of the macro-level causes of terrorism. The unique dataset is comprised of terrorist events and measures of social, political and economic contexts in 185 countries worldwide between the years 1970 and 2004. The theories are assessed using the iterative expert data mining (IEDM) methodology with classification mining and then association mining. The resulting 100 rules suggest that the level of democracy in a country is an integral part of the explanation for terrorism. This research shows that a multi-method data mining approach can be used to test competing theories in a discipline by analysing large, comprehensive datasets that capture multiple theories and include large numbers of records.

A Robust MEMS Based Multi-Component Sensor for 3D Borehole Seismic Arrays
The objective of this project was to develop, prototype and test a robust multi-component sensor that combines both Fiber Optic and MEMS technology for use in a borehole seismic array. The use such FOMEMS based sensors allows a dramatic increase in the number of sensors that can be deployed simultaneously in a borehole seismic array. Therefore, denser sampling of the seismic wave field can be afforded, which in turn allows us to efficiently and adequately sample P-wave as well as S-wave for high-resolution imaging purposes. Design, packaging and integration of the multi-component sensors and deployment system will target maximum operating temperature of 350-400 F and a maximum pressure of 15000-25000 psi, thus allowing operation under conditions encountered in deep gas reservoirs. This project aimed at using existing pieces of deployment technology as well as MEMS and fiber-optic technology. A sensor design and analysis study has been carried out and a laboratory prototype of an interrogator for a robust borehole seismic array system has been assembled and validated.

Dynamic characteristic testing for MEMS micro-devices with base excitation
The study of the dynamic characteristics of MEMS micro-devices depends on relevant testing facilities. Testing with a base excitation method was studied and employed in practical tests. A system for the dynamic characteristic testing of MEMS micro-devices was built based on a PZT transducer as the shock excitation source. A high voltage power source for the PZT transducer, which can provide large transient current, was developed for impact generation. Experiments for testing micro piezoelectric cantilevers were accomplished with the base excitation method. The impact response, i.e. electric charge signal generated by the micro piezoelectric cantilever, was acquired. By performing spectral analysis and comparison of the result with another cantilever having different resonance frequencies, the resonance frequency of the tested microstructure was determined. For comparison, simulation of the piezoelectric cantilever with a finite element analysis (FEA) method was carried out. Because the theory analysis is in good agreement with the experiment results, it can be used to estimate the actual resonance frequency of the tested microstructure. The base excitation method was also applied in the dynamic testing of microstructures under a high-g force environment. By the exclusion of the resonance peaks of PZT transducer and noise frequencies, the resonance frequency of the tested microstructure was determined. The applicability and the limitation of the method were briefly discussed.

Influence of Dzyaloshinshkii-Moriya interaction on quantum correlations in two qubit Werner states and MEMS
In this paper we study the influence of Dzyaloshinskii-Moriya (DM) interaction on quantum correlations in two qubit Werner states and maximally entangled mixed states (MEMS). We consider our system as a closed system of a qubits pair and one auxiliary qubit which interact with any one of the qubit of the pair through DM interaction. We show that DM interaction, taken along any direction (x or y or z), does not affect two qubit Werner states. On the other hand the MEMS are affected by x and z components of DM interaction and remain unaffected by the y component. Further, we find that the state (i.e probability amplitude) of auxiliary qubit do not affect the quantum correlations in both the states, only DM interaction strength influences the quantum correlations. So one can avoid the intention to prepare the specific state of auxiliary qubit to manipulate the quantum correlations in both the states. We mention here that avoiding the preparation of state can contribute to cost reduction in quantum information processing. We also observe the phenomenon of entanglement sudden death in the present study.

Method of forming a package for MEMS-based fuel cell
A MEMS-based fuel cell package and method thereof is disclosed. The fuel cell package comprises seven layers: (1) a sub-package fuel reservoir interface layer, (2) an anode manifold support layer, (3) a fuel/anode manifold and resistive heater layer, (4) a Thick Film Microporous Flow Host Structure layer containing a fuel cell, (5) an air manifold layer, (6) a cathode manifold support structure layer, and (7) a cap. Fuel cell packages with more than one fuel cell are formed by positioning stacks of these layers in series and/or parallel. The fuel cell package materials such as a molded plastic or a ceramic green tape material can be patterned, aligned and stacked to form three dimensional microfluidic channels that provide electrical feedthroughs from various layers which are bonded together and mechanically support a MEMS-based miniature fuel cell. The package incorporates resistive heating elements to control the temperature of the fuel cell stack. The package is fired to form a bond between the layers and one or more microporous flow host structures containing fuel cells are inserted within the Thick Film Microporous Flow Host Structure layer of the package.

Encouraging re-mining and reclamation of abandoned mined lands in Appalachia: Policy options
Abandoned mined lands (AML) are areas that were mined prior to implementation of federal controls over coal-mined land reclamation and were inadequately reclaimed. The majority of the US`s AML acreages were produced by coal mining in the Appalachian areas. Environmental problems include lands in barren or semi-barren condition, excessive sedimentation, acid water discharges, and unstable slopes. This article address the potential to reclame AMLs in the Appalachian region by creating incentives for environmental enhancement through re-mining. Background information of AML and on current policies affecting re-mining are reviewed and the results of a survey of individuals who are knowledgeable in remining policy issues are reported. 7 refs., 3 figs., 3 tabs.

Probable hydrologic effects of subsurface mining
This case history provides information on the ground-water system and presents the results of an analysis of present and future hydrologic effects of coal mining in the Appalachian coal basin. Although emphasis is on the probable hydrologic effects due to subsurface mining, examples and discussions are equally applicable to surface mine problems. The case history is based on an ongoing study in Greene County which will be completed in 1983. Cooperators in this project were the Pennsylvania Geologic and Topographic Survey and the Greene County Commissioners. The study stemmed from local interest in the rural water supply of the county which is predominantly groundwater.

HV Substation Earthing Design for Mines
Abstract:-High Voltage (HV) substation forms important assets for the mining industries. The existences of these substations necessitate earthing design to ensure safety compliance to the mine regulations. The HV system within the mines is consisted of multiple substations which are connected throughout and underground cable. These substations provide the load with the required electrical power to perform its tasks. This paper endeavours to provide information in regards to the different types of connections between the load and the substations (TT, TN and IT Systems). Furthermore, the earthing arrangements under different connection were assessed. A case study is addressed to show the different earthing arrangements under different connection systems Keywords:- Earth Grid, EPR, Fault Current, High Voltage, Mines, TN and TT systems I.

Fuelcell-Hybrid Mine loader (LHD)
The fuel cell hybrid mine loader project, sponsored by a government-industry consortium, was implemented to determine the viability of proton exchange membrane (PEM) fuel cells in underground mining applications. The Department of Energy (DOE) sponsored this project with cost-share support from industry. The project had three main goals: (1) to develop a mine loader powered by a fuel cell, (2) to develop associated metal-hydride storage and refueling systems, and (3) to demonstrate the fuel cell hybrid loader in an underground mine in Nevada. The investigation of a zero-emissions fuel cell power plant, the safe storage of hydrogen, worker health advantages (over the negative health effects associated with exposure to diesel emissions), and lower operating costs are all key objectives for this project.

The use of geographical information system (GIS) technology in surface mine reclamation monitoring
The use of a Geographic Information System (GIS) and related technologies (e.g., Digital cartographic tools, satellite image processing systems) can benefit the planning and monitoring of open-pit mine reclamation activities. PCI Geomatics, in conjunction with Luscar Limited's Line Creek Mine, has developed a GIS-based system designed to store information relevant to planning and assessing reclamation progress. Data that existed in various formats throughout the company, and which had been collected since the mine-planning phase, was integrated into the GIS. The system is used to summarize current reclamation activities and is linked to corporate costing procedures. Monitoring of reclamation activities and quantifying change in the mine area is easily done using the spatial analysis capabilities of the GIS. Assessments of the change in reclamation areas are enhanced by using satellite image data to produce inexpensive and timely information on the land base, and allow the comparison of the health of the vegetation to reclamation areas from year to year. The implemented system substantially reduces the time needed to generate statistics and produce maps for government or internal reports. Also, there are benefits in terms of both cost and effectiveness of reclamation planning.

Radon releases from Australian uranium mining and milling projects: assessing the UNSCEAR approach
The release of radon gas and progeny from the mining and milling of uranium-bearing ores has long been recognised as a potential radiological health hazard. The standards for exposure to radon and progeny have decreased over time as the understanding of their health risk has improved. In recent years there has been debate on the long-term releases (10,000 years) of radon from uranium mining and milling sites, focusing on abandoned, operational and rehabilitated sites. The primary purpose has been estimates of the radiation exposure of both local and global populations. Although there has been an increasing number of radon release studies over recent years in the USA, Australia, Canada and elsewhere, a systematic evaluation of this work has yet to be published in the international literature. This paper presents a detailed compilation and analysis of Australian studies. In order to quantify radon sources, a review of data on uranium mining and milling wastes in Australia, as they influence radon releases, is presented. An extensive compilation of the available radon release data is then assembled for the various projects, including a comparison to predictions of radon behaviour where available. An analysis of cumulative radon releases is then developed and compared to the UNSCEAR approach. The implications for the various assessments of long-term releases of radon are discussed, including aspects such as the need for ongoing monitoring of rehabilitation at uranium mining and milling sites and life-cycle accounting.

Regulating for the long term: SMCRA and acid mine drainage
With the passage of the Surface Mining Control and Reclamation Act of 1977 (SMCRA), regulators and industry representatives expected to solve the problem of pollution of the Nation`s waterways caused by acidic discharges from coal mines. Eighteen years after the passage of SMCRA, hard issues of predicting, regulating and treating acid mine drainage remain. Acid mine drainage is most common in the coal seams of the Midwest and Appalachia: Pennsylvania, West Virginia, Maryland, Ohio, Illinois, and Tennessee. This article discusses regulation of coal mines and acid mine drainage for the long term.

4D seismic data acquisition method during coal mining
In order to observe overburden media changes caused by mining processing, we take the fully-mechanized working face of the BLT coal mine in Shendong mine district as an example to develop a 4D seismic data acquisition methodology during coal mining. The 4D seismic data acquisition is implemented to collect 3D seismic data four times in different periods, such as before mining, during the mining process and after mining to observe the changes of the overburden layer during coal mining. The seismic data in the research area demonstrates that seismic waves are stronger in energy, higher in frequency and have better continuous reflectors before coal mining. However, all this is reversed after coal mining because the overburden layer has been mined, the seismic energy and frequency decrease, and reflections have more discontinuities. Comparing the records collected in the survey with those from newly mined areas and other records acquired in the same survey with the same geometry and with a long time for settling after mining, it clearly shows that the seismic reflections have stronger amplitudes and are more continuous because the media have recovered by overburden layer compaction after a long time of settling after mining. By 4D seismic acquisition, the original background investigation of the coal layers can be derived from the first records, then the layer structure changes can be monitored through the records of mining action and compaction action after mining. This method has laid the foundation for further research into the variation principles of the overburden layer under modern coal-mining conditions.

Surface mining environmental monitoring and reclamation handbook
The Surface Mining Environmental Monitoring and Reclamation Handbook has been expressly designed to meet the statutory requirements of surface coal mining and reclamation. It sets forth a range of monitoring techniques in a manner that is most likely to be of direct, practical, and cost-effective use to the widest expanse of mining-reclamation situations. A literature review identifies and evaluates those published sources of information that are most applicable to the needs of handbook users. This is supplemented by identifying other sources of pertinent information with particular attention paid to local, state, and federal agencies that can supply data required for mining and reclamation efforts. Attention is then directed toward the means whereby regulatory requirements can be satisfied. An effort has been made to identify those areas likely to present special problems. And, finally, where appropriate, modeling techniques are described and the extent of their utility delineated. Throughout, the handbook has maintained a practical focus. It attempts to provide surface coal mine operators with the tools and techniques needed to meet legal environmental and monitoring requirements without an unnecessary and costly overexpenditure of time and money. The provision of a range of alternatives to meet various obligations, the stress on using existing resources whenever possible, and the careful differentiation of means and ends are all directed toward the best ways to meet regulatory requirements.

Noise exposures in US coal mines
Mine Safety and Health Administration (MSHA) inspectors conduct full-shift environmental noise surveys to determine the occupational noise levels to which coal miners are exposed. These noise surveys are performed to determine compliance with the noise standard promulgated under the Federal Mine Safety and Health Act of 1977. Data from over 60,000 full-shift noise surveys conducted from fiscal year 1986 through 1992 were entered into a computer data base to facilitate analysis. This paper presents the mean and standard deviation of over 60,000 full-shift noise dose measurements for various underground and surface coal mining occupations. Additionally, it compares and contrasts the levels with historical noise exposure measurements for selected coal mining occupations that were published in the 1970`s. The findings were that the percentage of miners surveyed that were subjected to noise exposures above 100%, neglecting personal hearing protectors, were 26.5% and 21.6% for surface and underground mining, respectively. Generally, the trend is that the noise exposures for selected occupations have decreased since the 1970`s.

An integrated system to utilize the waste coal mine methane (CMM) at the Federal No. 2 Coal Mine in West Virginia was designed and built. The system includes power generation, using internal combustion engines, along with gas processing equipment to upgrade sub-quality waste methane to pipeline quality standards. The power generation has a nominal capacity of 1,200 kw and the gas processing system can treat about 1 million cubic feet per day (1 MMCFD) of gas. The gas processing is based on the Northwest Fuel Development, Inc. (NW Fuel) proprietary continuous pressure swing adsorption (CPSA) process that can remove nitrogen from CMM streams. The two major components of the integrated system are synergistic. The byproduct gas stream from the gas processing equipment can be used as fuel for the power generating equipment. In return, the power generating equipment provides the nominal power requirements of the gas processing equipment. This Phase III effort followed Phase I, which was comprised of a feasibility study for the project, and Phase II, where the final design for the commercial-scale demonstration was completed. The fact that NW Fuel is desirous of continuing to operate the equipment on a commercial basis provides the validation for having advanced the project through all of these phases. The limitation experienced by the project during Phase III was that the CMM available to operate the CPSA system on a commercial basis was not of sufficiently high quality. NW Fuel's CPSA process is limited in its applicability, requiring a relatively high quality of gas as the feed to the process. The CPSA process was demonstrated during Phase III for a limited time, during which the processing capabilities met the expected results, but the process was never capable of providing pipeline quality gas from the available low quality CMM. The NW Fuel CPSA process is a low-cost ''polishing unit'' capable of removing a few percent nitrogen. It was never intended to process CMM streams containing high levels of nitrogen, as is now the case at the Federal No.2 Mine. Even lacking the CPSA pipeline delivery demonstration, the project was successful in laying the groundwork for future commercial applications of the integrated system. This operation can still provide a guide for other coal mines which need options for utilization of their methane resources. The designed system can be used as a complete template, or individual components of the system can be segregated and utilized separately at other mines. The use of the CMM not only provides an energy fuel from an otherwise wasted resource, but it also yields an environmental benefit by reducing greenhouse gas emissions. The methane has twenty times the greenhouse effect as compared to carbon dioxide, which the combustion of the methane generates. The net greenhouse gas emission mitigation is substantial.

Influence of lithology on longwall mining subsidence
The US Bureau of Mines assessed the geological effects on the ratio of maximum subsidence and extraction thickness, known as the subsidence factor, to develop a simple method for predicting the maximum subsidence. This study is restricted to the Northern Appalachian Coal Basin where data were collected from 13 coal mines. A model previously developed to relate the subsidence factor with the lithology and with the width and depth of working panels was used in the assessment. The result shows the possibility of determining maximum subsidence without resorting to a rigorous method.

Reduction of fire hazards on large mining equipment
Although standards and regulations are in place to prevent large mining equipment fires, recent analyses of mine accident data show that mining equipment fires still occur with alarming frequency and grave consequences, particularly at all surface mines and in underground metal/nonmetal mines. Recently technological advances in fire protection, combined with the statistical data on equipment fires, led NIOSH to reinvestigate this and to improve operator safety. NIOSH demonstrated that newly developed technologies, such as dual cab fire inerting systems and engine compartment fire barriers, can greatly enhance operator safety and lessen the damage of property during large mobile equipment fires. 10 refs., 5 figs.

Nano-imprinting lithography of P(VDF�TrFE�CFE) for flexible freestanding MEMS devices
Thermoplastic nano-imprinting lithography (T-NIL) has been used for the first time as a method of creating freestanding smooth and patterned membranes of micron scale thickness using poly (vinylidene fluoride�trifluoroethylene�chlorofluoroethylene) [P(VDF�TrFE�CFE)]. PVDF and its copolymers and terpolymers cannot be processed using classical lithography techniques because it is incompatible with most solvents and photoresist developers. In this work, patterning at micron scale resolution and creating freestanding layers is facilitated by means of a hydrophobic dodecyltrichlorosilane layer deposited on the silicon (Si) prior to imprinting. This surface treatment reduces the adhesion between the polymer and Si substrate or stamp, aiding with mould release. A sacrificial layer beneath a spin-coated layer of P(VDF�TrFE�CFE) is presented as an alternative method of creating freestanding membranes. The latter method was used in conjunction with exploiting the thermoplastic properties of P(VDF�TrFE�CFE) during T-NIL to improve the quality of the patterned freestanding layers. The cured membrane thicknesses ranged from 0.4�5.8�?m with diameters of centimeters order of magnitude. The processes presented here comprise a basis for integrating P(VDF�TrFE�CFE) as an active material in three dimensional electro-active polymeric microelectromechanical system (MEMS) devices.

Development of surface mine cost estimating equations
Cost estimating equations were developed to determine capital and operating costs for five surface coal mine models in Central Appalachia, Northern Appalachia, Mid-West, Far-West, and Campbell County, Wyoming. Engineering equations were used to estimate equipment costs for the stripping function and for the coal loading and hauling function for the base case mine and for several mines with different annual production levels and/or different overburden removal requirements. Deferred costs were then determined through application of the base case depreciation schedules, and direct labor costs were easily established once the equipment quantities (and, hence, manpower requirements) were determined. The data points were then fit with appropriate functional forms, and these were then multiplied by appropriate adjustment factors so that the resulting equations yielded the model mine costs for initial and deferred capital and annual operating cost. (The validity of this scaling process is based on the assumption that total initial and deferred capital costs are proportional to the initial and deferred costs for the primary equipment types that were considered and that annual operating cost is proportional to the direct labor costs that were determined based on primary equipment quantities.) Initial capital costs ranged from $3,910,470 in Central Appalachia to $49,296,785; deferred capital costs ranged from $3,220,000 in Central Appalachia to $30,735,000 in Campbell County, Wyoming; and annual operating costs ranged from $2,924,148 in Central Appalachia to $32,708,591 in Campbell County, Wyoming.

Presently the mining of Florida phosphate requires the movement of over a 100-ton of materials (overburden, sand, clay) for every ton of phosphate concentrate recovered. Not only is this energy intensive, but it also causes significant stress on the environment. In 2003, the Department of Energy solicited ideas for innovative mining ideas that could significantly improve the efficiency of mining. An award was made to the University of Florida Engineering Research Center to evaluate the in situ mining of phosphates using an aqueous CO{sub 2} solution. Tests were carried out in a 15.2 cm (6-inch) diameter column, 1.83 meter (6 feet) long at pressures up to 117.2 kg/cm{sup 2} (40 psi). Results to date demonstrate that initially the MgO is leached from the ore and then the phosphate. While the tests are continuing, so far they have not demonstrated P{sub 2}O{sub 5} concentrations that are economically attractive.

Selective mining and beneficiation at Grootegeluk coal mine Waterberg Coalfield, South Africa
Grootegeluk Coal Mine, situated in the Waterberg Coalfield in the Northern Province of South Africa, ranks among the largest open pit coal mines in the world in terms of run of mine tonnage. Commissioned in 1980 to provide steel producer Iscor with coking coal, Grootegeluk currently produces 53 Mt of coking coal per annum. At present Iscor consumes 1.2 Mt of coking coal while Matimba, the world's largest direct dry cooled PowerStation consumes an additional 12.6 Mt. Fine washing and screening plants currently beneficiate the run of mine feed from this multi-seam multi-product mine. Although the Waterberg Coalfield contains approximately 50% of South Africa's coal reserves, Grootegeluk is the only operating mine in this coalfield. The coal seams of the Waterberg Coalfield occur in the Volksrust and Vryheids formations of the Karoo Sequence. Numerous coal seams ranging from a few millimeters up to 8 meters occur over a stratigraphic thickness of at least 120 meters. These coal seams are grouped into eleven coal bearing zones that can be correlated across the coalfield. The coal- and coalbearing strata in the Waterberg are of late Paleozoic to early Mesozoic age. Coal from the Volksrust formation is autochthonous while the coal from the Vryheid formation is allochthonous. To ensure that sufficient geological and analytical data are obtained from exploration boreholes an extensive sampling procedure was established with washability data ranging from 1,35 to 2,20 g/cc. The analyses indicated that certain parts of the coalbearing strata is not suitable for the production of coking coal due to the high phosphorus content or the poor coking properties. This resulted in an open pit with 11 mining benches. The upper parts of the deposit is extracted by conventional shovel and truck operations while the coal seams of the lower part of the deposit are mined selectively with hydraulic shovels. At Grootegeluk down the hole geophysics (natural gamma) are used for grade control and also to quantify the effect of over- or undermining on the various mining benches. Reconciliation between the run of mine material dispatched to the various plants and their resulted yields/qualities are done regularly.

Aluminum Nitride Micro-Channels Grown via Metal Organic Vapor Phase Epitaxy for MEMs Applications
Aluminum nitride (AlN) is a promising material for a number of applications due to its temperature and chemical stability. Furthermore, AlN maintains its piezoelectric properties at higher temperatures than more commonly used materials, such as Lead Zirconate Titanate (PZT) [1, 2], making AlN attractive for high temperature micro and nanoelectromechanical (MEMs and NEMs) applications including, but not limited to, high temperature sensors and actuators, micro-channels for fuel cell applications, and micromechanical resonators. This work presents a novel AlN micro-channel fabrication technique using Metal Organic Vapor Phase Epitaxy (MOVPE). AlN easily nucleates on dielectric surfaces due to the large sticking coefficient and short diffusion length of the aluminum species resulting in a high quality polycrystalline growth on typical mask materials, such as silicon dioxide and silicon nitride [3,4]. The fabrication process introduced involves partially masking a substrate with a silicon dioxide striped pattern and then growing AlN via MOVPE simultaneously on the dielectric mask and exposed substrate. A buffered oxide etch is then used to remove the underlying silicon dioxide and leave a free standing AlN micro-channel. The width of the channel has been varied from 5 �m to 110 �m and the height of the air gap from 130 nm to 800 nm indicating the stability of the structure. Furthermore, this versatile process has been performed on (111) silicon, c-plane sapphire, and gallium nitride epilayers on sapphire substrates. Reflection High Energy Electron Diffraction (RHEED), Atomic Force Microscopy (AFM), and Raman measurements have been taken on channels grown on each substrate and indicate that the substrate is influencing the growth of the AlN micro-channels on the SiO2 sacrificial layer.

Marine clathrate mining and sediment separation
A method and apparatus for mining of hydrocarbons from a hydrocarbon-containing clathrate such as is found on the ocean floor. The hydrocarbon containing clathrate is disaggregated from sediment by first disrupting clathrate-containing strata using continuous mining means such as a rotary tilling drum, a fluid injector, or a drill. The clathrate-rich portion of sediment thus disrupted from the sea floor strata are carried through the apparatus to regions of relative lower pressure and/or relative higher temperature where the clathrate further dissociates into component hydrocarbons and water. The hydrocarbon is recovered with the assistance of a gas that is injected and buoys the hydrocarbon containing clathrate helping it to rise to regions of lower pressure and temperature where hydrocarbon is released. The sediment separated from the hydrocarbon returns to the ocean floor.

This project evaluated the technical, economic and environmental feasibility of filling abandoned underground mine voids with coal combustion byproducts. Success was measured in terms of technical feasibility of the approach (i.e. % void filling), cost, environmental benefits (acid mine drainage and subsidence control) and environmental impacts (noxious ion release). Phase 1 of the project was completed in September 1995 and was concerned with the development of the grout and a series of predictive models. These models were verified through the Phase II field phase and will be further verified fin the large scale field demonstration of Phase III. The verification allows the results to be packaged in such a way that the technology can be easily adapted to different site conditions. Phase II was successfully completed with 1000 cubic yards of grout being injected into Anker Energy's Fairfax mine. The grout flowed over 600 feet from a single injection borehole. The grout achieved a compressive strength of over 1000 psi (twice the level that is needed to guarantee subsidence control). Phase III was a full scale test at Anker's eleven acre Longridge mine site. The CCB grout replaced what was an open mine void with a solid so that the groundwater tends to flow around and through the pillars rather than through the previously mined areas. The project has demonstrated that CCBs can be successfully disposed in underground mines. Additionally, the project has shown that filling an abandoned underground mine with CCBs can lead to the reduction and elimination of environmental problems associated with underground mining such as acid mine drainage and subsidence. The filling of the Longridge Mine with 43,000 cubic yards of CCB grout resulted in a 97% reduction in acid mine drainage coming from the mine.

Capture and Use of Coal Mine Ventilation-Air Methane
Capture and use of Coal Mine Capture and use of Coal Mine Ventilation - air Methane Background Methane emissions from coal mines represent about 10 percent of the U.S. anthropogenic methane released to the atmosphere. Methane-the second most important non-water greenhouse gas-is 21 times as powerful as carbon dioxide (CO 2 ) in its global warming potential. Ventilation-air methane (VAM)-the exhaust air from underground coal mines-is the largest source of coal mine methane, accounting for about half of the methane emitted from coal mines in the United States. Unfortunately, because of the low methane concentration (0.3-1.5 percent) in ventilation air, its beneficial use is difficult. However, oxidizing the methane to CO 2 and water reduces its global warming potential by 87 percent. A thermal

Design of coal mine roof support and yielding pillars for longwall mining in the Appalachian coalfield
In this thesis, the existing Geomechanics Classification (Bieniawski, 1979) was modified for use in underground coal mines through the introduction of adjustment modifiers for strata weathering, horizontal stress, and roof support. Sixty-two roof case histories were collected from two mines exploiting the Pittsburgh and Lower Kittanning coal seams. Geologic and material property variables were examined with respect to supported stand-up time, while survival and regression analyses were used in deriving the adjustment multipliers. Guidelines for roofspan selection and roof support design were an integral facet of the modified classification scheme. Tentative design guidelines for chain pillars are provided on the basis of a field investigation and numerical modeling of longwall chain pillar behavior. A longwall chain pillar was instrumented with vibrating wire stressmeters to quantify the change in stress distribution as longwall mining proceeded out by the pillar. A sonic probe was used to conduct a velocity profile across the pillar before and after mining to delineate the failed and stable regions of the pillar. Velocity profiles across the pillar were supplemented by an examination of changes in the dynamic modulus and the shear wave frequency. The main contributions of the research lies in: (i) modifications introduced to the Geomechanics Classification (RMR System), (ii) the correlation between changes in pillar stress and the extent of the yield zone surrounding a longwall chain pillar, and (iii) the proposal of design procedures involving coal mine roof support and chain pillars. Numerical examples obtained from mine case histories are provided to illustrate the use of the design procedures.

Land reclamation and strip-mined coal production in appalachia
This study quantifies the short-run impacts of reclamation on strip mining costs, coal prices, production, and employment in Appalachia. A process analysis model is developed and used to estimate short-run strip-mined coal supply functions under conditions of alternative reclamation requirements. Then, an econometric model is developed and used to estimate coal demand relations. Our results show that full reclamation has rather minor impacts. In 1972, full reclamation would have increased strip-mined coal production costs an average of $0.35 per ton, reduced strip-mined coal production by 10 million tons, and cost approximately 1600 jobs in Appalachia.

Sugarbush system: a post-mining land use alternative
Viable, potentially-profitable, post-mining options for high elevation sites in the Appalachian coal fields are limited. Sugar maple groves designed for long term profitable system operation seems to be one such option. This is a design document for a sugarbush system with equations for optimizing the system, subject to local constraints. Mine land reclamation specialists may consider and explore options using an available computer program (IBM-PC BASIC). Creating a sugarbush may suggest the long term interest of some mined-land owners in their land and it may represent an acceptable post-mining alternative on some sites to conventional reclamation practices. 20 references, 2 figures, 2 tables.

Atomistic modeling of nanowires, small-scale fatigue damage in cast magnesium, and materials for MEMS.
Lightweight and miniaturized weapon systems are driving the use of new materials in design such as microscale materials and ultra low-density metallic materials. Reliable design of future weapon components and systems demands a thorough understanding of the deformation modes in these materials that comprise the components and a robust methodology to predict their performance during service or storage. Traditional continuum models of material deformation and failure are not easily extended to these new materials unless microstructural characteristics are included in the formulation. For example, in LIGA Ni and Al-Si thin films, the physical size is on the order of microns, a scale approaching key microstructural features. For a new potential structural material, cast Mg offers a high stiffness-to-weight ratio, but the microstructural heterogeneity at various scales requires a structure-property continuum model. Processes occurring at the nanoscale and microscale develop certain structures that drive material behavior. The objective of the work presented in this report was to understand material characteristics in relation to mechanical properties at the nanoscale and microscale in these promising new material systems. Research was conducted primarily at the University of Colorado at Boulder to employ tightly coupled experimentation and simulation to study damage at various material size scales under monotonic and cyclic loading conditions. Experimental characterization of nano/micro damage will be accomplished by novel techniques such as in-situ environmental scanning electron microscopy (ESEM), 1 MeV transmission electron microscopy (TEM), and atomic force microscopy (AFM). New simulations to support experimental efforts will include modified embedded atom method (MEAM) atomistic simulations at the nanoscale and single crystal micromechanical finite element simulations. This report summarizes the major research and development accomplishments for the LDRD project titled 'Atomistic Modeling of Nanowires, Small-scale Fatigue Damage in Cast Magnesium, and Materials for MEMS'. This project supported a strategic partnership between Sandia National Laboratories and the University of Colorado at Boulder by providing funding for the lead author, Ken Gall, and his students, while he was a member of the University of Colorado faculty.

Sustainable heat extraction from abandoned mine tunnels: A numerical model
Abandoned mines are often associated with enduring liabilities which involve significant costs for decades after the decommissioning of the mine. Using a decommissioned mine as a geothermal resource can offset the environmental costs by supplying green heat to the communities living in and around the mine area. In this paper a numerical assessment of geothermal heat extraction from underground mine workings using an open loop geothermal system is carried out. In this study our focus is on fully flooded mines where the heat flow from the rock mass to the mine cavities is dominantly controlled by conduction in the rock mass. The sustainable heat flux into the mine workings is assessed using a transient two-dimensional axisymmetric heat transfer model. Finite volume method is applied to solve the model and simulate the transient temperature fields in the rock mass and within the water (flowing through cavities). The model is capable of controlling the rate of heat extraction through continuous adjustment of the rate of water flow through the mine. Sustainable rate of heat extraction is calculated for seasonally varied heat loads and for different project life cycles. It is shown that with proper resource management each kilometre of a typical deep underground mine tunnel can produce about 150?kW of usable heat in a sustainable manner. The model is validated by comparing its results with other published models and realistic data available from Springhill mine Nova Scotia Canada. It is found that the sustainable heat extraction is controlled dominantly by virgin rock temperature thermal conductivity of the rock mass and seasonal heat load variations.

WebUser: mining unexpected web usage
Web usage mining has been much concentrated on the discovery of relevant user behaviours from web access record data. In this paper, we present WebUser, an approach to discover unexpected usage in web access log. We present a belief-driven method for extracting unexpected web usage sequences, where the belief system consists of a temporal relation and semantics constrained sequence rules acquired with respect to prior knowledge. Our experiments show the effectiveness and usefulness of the proposed approach. Furthermore, discovered rules of unexpected web usage can be used for web content personalisation and recommendation, site structure optimisation and critical event prediction.

Inflatable partition for fighting mine fires
The seal is a lightweight, inflatable, bag which may be inflated by a portable air generator and is used to seal a burning mine passage. A collapsible tube-like aperture extends through the seal and allows passage of high expansion foam through the seal in a feed tube. The foam fills the passageway and extinguishes the fire. In other embodiments, the feed tubes incorporate means to prevent collapse of the aperture. In these embodiments a shroud connects the feed tube to a foam generator. This seal allows creation of a high expansion foam fire fighting barrier even in upward sloping passages.

Case study of groundwater impact caused by underground mining
An investigative methodology is presented to assist mining and regulatory personnel in determining the effect underground mining can have on local aquifers in the Appalachian coal region. The impact of underground mining on groundwater may be more extensive than first realized by the mining industry and regulatory agencies. The primary reason for this possible under-assessment of deep mining's influence on groundwater is the methods used to calculate groundwater movement. Since groundwater calculations are based on primary hydraulic conductivity, i.e. the conductivity through solid rock measured from rock core samples, erroneous results may be expected. In many cases, groundwater flow times and the corresponding areas of influence are much greater than those assumed since water is rapidly moved through fractured zones that commonly occur throughout Appalachia. A case study illustrating this phenomenon is drawn from underground mining operations in Pike County. A survey of 144 wells was conducted to determine if any loss of water supply and/or quality was found. This was correlated to the extent and time progression of underground mining operations. Other parameters qualified are water level fluctuations, groundwater quality, precipitation, seasonal effects, geology, and mine dewatering. The analysis includes a comprehensive compilation of a well inventory of domestic water supplies. The case study draws conclusions regarding cause and effect relationships.

Mining API Error-Handling Specifications from Source Code
Abstract. API error-handling specifications are often not documented, necessitating automated specification mining. Automated mining of error-handling specifications is challenging for procedural languages such as C, which lack explicit exception-handling mechanisms. Due to the lack of explicit exception handling, error-handling code is often scattered across different procedures and files making it difficult to mine error-handling specifications through manual inspection of source code. In this paper, we present a novel framework for mining API errorhandling specifications automatically from API client code, without any user input. In our framework, we adapt a trace generation technique to distinguish and generate static traces representing different API run-time behaviors. We apply data mining techniques on the static traces to mine specifications that define correct handling of API errors. We then use the mined specifications to detect API error-handling violations. Our framework mines 62 error-handling specifications and detects 264 real error-handling defects from the analyzed open source packages. 1 1

Radio-Ecological Situation in the Area of the Priargun Production Mining and Chemical Association - 13522
'The Priargun Production Mining and Chemical Association' (hereinafter referred to as PPMCA) is a diversified mining company which, in addition to underground mining of uranium ore, carries out refining of such ores in hydrometallurgical process to produce natural uranium oxide. The PPMCA facilities are sources of radiation and chemical contamination of the environment in the areas of their location. In order to establish the strategy and develop criteria for the site remediation, independent radiation hygienic monitoring is being carried out over some years. In particular, this monitoring includes determination of concentration of the main dose-forming nuclides in the environmental media. The subjects of research include: soil, grass and local foodstuff (milk and potato), as well as media of open ponds (water, bottom sediments, water vegetation). We also measured the radon activity concentration inside surface workshops and auxiliaries. We determined the specific activity of the following natural radionuclides: U-238, Th-232, K-40, Ra-226. The researches performed showed that in soil, vegetation, groundwater and local foods sampled in the vicinity of the uranium mines, there is a significant excess of {sup 226}Ra and {sup 232}Th content compared to areas outside the zone of influence of uranium mining. The ecological and hygienic situation is as follows: - at health protection zone (HPZ) gamma dose rate outdoors varies within 0.11 to 5.4 ?Sv/h (The mean value in the reference (background) settlement (Soktui-Molozan village) is 0.14 ?Sv/h); - gamma dose rate in workshops within HPZ varies over the range 0.14 - 4.3 ?Sv/h. - the specific activity of natural radionuclides in soil at HPZ reaches 12800 Bq/kg and 510 Bq/kg for Ra-226 and Th-232, respectively. - beyond HPZ the elevated values for {sup 226}Ra have been registered near Lantsovo Lake - 430 Bq/kg; - the radon activity concentration in workshops within HPZ varies over the range 22 - 10800 Bq/m{sup 3}. The seasonal dependence of radon activity concentration is observed in the air of workshops (radon levels are lower in winter in comparison with spring-summer period). - in drinking water, intervention levels by gross alpha activity and by some radionuclides, in particular by Rn-222, are in excess. Annual effective dose of internal exposure due to ingestion of such water will be 0.14-0.28 mSv. (authors)

Because specific reclamation guidelines did not exist at the time, the overburden was not replaced and the mined site was simply planted to grass or trees, without performing grading or reclamation. After 1972, the Ohio Mineland Reclamation Act mandated that mined sites be graded to restore their original topography and

Economic environment of coal mining operations in Appalachia, United States
Appalachia is a mountainous coal region, in the United States, where the small mining operation dominates. The large number of small coal operations makes the coal industry in that area very competitive, the industry concentration ratio being low. The vast majority of the small coal operations are contractors and nonunionized. There are various circumstances under which a large company will elect to supplement their coal production from their, usually larger, coal mines. The size of the coal mine is generally dictated by the size and location of the coal reserves. The optimum rate of coal extraction, and hence the life of the mine, is a factor of the size of the coal reserves and the contribution margin (coal price less variable cost). Large companies tend to have better safety records than smaller companies due to greater numbers of professional engineers and better management. Small mines have the advantage of closer supervision.

Geologic considerations in underground coal mining system design
Geologic characteristics of coal resources which may impact new extraction technologies are identified and described to aid system designers and planners in their task of designing advanced coal extraction systems for the central Appalachian region. These geologic conditions are then organized into a matrix identified as the baseline mine concept. A sample region, eastern Kentucky, is next analyzed, using both the new baseline mine concept and traditional geologic investigative approach. The baseline mine concept presented is intended as a framework, providing a consistent basis for further analyses to be subsequently conducted in other geographic regions. The baseline mine concept is intended as a tool to give system designers a more realistic feel of the mine environment and will hopefully lead to acceptable alternatives for advanced coal extraction system.

JGI - Why Sequence Euryarchaeota in Acid Mine Drainage?
Euryarchaeota in Acid Mine Drainage? Euryarchaeota in Acid Mine Drainage? Acid mine drainage (AMD) is a major worldwide environmental problem associated with the mining of energy resources (coal and uranium) and metals (eg., iron and copper), thus of direct DOE relevance. The processes that underpin AMD formation can be harnessed for bioleaching and bioremediation. Many scientific and industrial groups are studying various aspects of the biogeochemistry of AMD generation. Random shotgun sequencing of an extremely acidic (pH <0.9) chemolithotrophic subsurface AMD biofilm community (from the Richmond Mine in Iron Mountain, California) recovered a genome fragment from a novel euryarchaeon, named WTF-1. This novel lineage was previously missed by common broad-specificity primers used for PCR-based surveys. Further study

Gasoline and Diesel Fuel Update (EIA)
Industrial Industrial International Energy Outlook 2010 Industrial Sector Energy Consumption Worldwide industrial energy consumption increases by 42 percent, or an average of 1.3 percent per year, from 2007 to 2035 in the IEO2010 Reference case. Ninety-five percent of the growth occurs in non-OECD nations. Overview The world's industries make up a diverse sector that includes manufacturing, agriculture, mining, and construction. Industrial energy demand varies across regions and countries, depending on the level and mix of economic activity and technological development, among other factors. Energy is consumed in the industrial sector for a wide range of activities, such as processing and assembly, space conditioning, and lighting. Industrial energy use also includes natural gas and petroleum products used as feedstocks to produce non-energy products, such as plastics. In aggregate, the industrial sector uses more energy than any other end-use sector, consuming about one-half of the world's total delivered energy.
Correlation cross sections along the international border
The Manitoba-North Dakota (Canada-US) stratigraphic correlation project is a joint study between the Petroleum Branch of Manitoba Energy and Mines and the North Dakota Geological Survey. It is an attempt to correlate the differing stratigraphic terminologies established in the two jurisdictions by providing a reference cross section across the international boundary. The study involves the subsurface correlation of logs of the Paleozoic and Mesozoic sequences in the Manitoba and North Dakota portions of the Williston basin. The Paleozoic and Mesozoic sequences are subdivided for presentation into the following stratigraphic intervals: (a) Cambrian-Ordovician-Silurian, (b) Devonian, (c) Mississippian, (d) Jurassic, and (e) Cretaceous. Wireline logs show the actual stratigraphic correlations. A nomenclature chart is also presented from each sequence. In addition, the sections include a generalized description of lithologies, thicknesses, environments of deposition, and petroleum potential for each geographic area.

Aquatic Ecosystem Enhancement at Mountaintop Mining Sites Symposium
Welcome to this symposium which is part of the ongoing effort to prepare an Environmental Impact Statement (EIS) regarding mountaintop mining and valley fills. The EIS is being prepared by the U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, U.S. Office of Surface Mining, and U.S. Fish and Wildlife Service, in cooperation with the State of West Virginia. Aquatic Ecosystem Enhancement (AEE) at mountaintop mining sites is one of fourteen technical areas identified for study by the EIS Interagency Steering Committee. Three goals were identified in the AEE Work Plan: 1. Assess mining and reclamation practices to show how mining operations might be carried out in a way that minimizes adverse impacts to streams and other environmental resources and to local communities. Clarify economic and technical constraints and benefits. 2. Help citizens clarify choices by showing whether there are affordable ways to enhance existing mining, reclamation, mitigation processes and/or procedures. 3. Ide identify data needed to improve environmental evaluation and design of mining projects to protect the environment. Today�s symposium was proposed in the AEE Team Work Plans but coordinated planning for the event began September 15, 1999 when representatives from coal industry, environmental groups and government regulators met in Morgantown. The meeting participants worked with a facilitator from the Canaan Valley Institute to outline plans for the symposium. Several teams were formed to carry out the plans we outlined in the meeting.

Natural radioactivity and radiation exposure at the Minjingu phosphate mine in Tanzania
In this paper the results of studies on activity and ambient radiation background around the Minjingu phosphate mine in Tanzania are presented. The outdoor dose rate in air and the activity levels of samples from and outside the mine were determined by thermoluminiscent dosimeters and a gamma spectrometer system with a Hyper Pure germanium detector system respectively. The determination of activity was made for the 226 Ra, 228 Ra, 228 Th and 40 K radionuclides. High concentrations of radium-226 were observed in phosphate rock (5760�107 Bq kg-1 ), waste rock (4250�98 Bq kg-1 ), wild leaf vegetation (650�11 Bq kg-1 ), edible leaf vegetation (393�9 Bq kg-1 ), surface water (4.7�0.4 mBq l-1 ) and chicken feed (4�0.1 Bq kg-1 ) relative to selected control sites. These findings suggest a radiation health risk particularly when the samples are ingested, because the internal exposure may give rise to an effective dose exceeding 20 mSv which is the annual limit of intake of natural radionuclides recommended by the ICRP. On the other hand, the radiation dose from ambient air over five years at the phosphate mine ranges from 1375 to 1475 nGy h-1 with an average of 1415 nGy h-1 . The average is about 28 times that of the global average background radiation from terrestrial sources, and about 12 times the allowed average dose limit for public exposure over five consecutive years. Future investigations on the occupancy factor, external dose rate and radon and radon progeny exposure in drinking water, buildings and activity content in the locally grown foodstuffs are proposed, for the realistic quantification of the overall exposure of workers and public at Minjingu, and remedial measures for future radiation safety.

US uranium mining industry: background information on economics and emissions
A review of the US uranium mining industry has revealed a generally depressed industry situation. The 1982 U/sub 3/O/sub 8/ production from both open-pit and underground mines declined to 3800 and 6300 tons respectively with the underground portion representing 46% of total production. US exploration and development has continued downward in 1982. Employment in the mining and milling sectors has dropped 31% and 17% respectively in 1982. Representative forecasts were developed for reactor fuel demand and U/sub 3/O/sub 8/ production for the years 1983 and 1990. Reactor fuel demand is estimated to increase from 15,900 tons to 21,300 tons U/sub 3/O/sub 8/ respectively. U/sub 3/O/sub 8/ production, however, is estimated to decrease from 10,600 tons to 9600 tons respectively. A field examination was conducted of 29 selected underground uranium mines that represent 84% of the 1982 underground production. Data was gathered regarding population, land ownership and private property valuation. An analysis of the increased cost to production resulting from the installation of 20-meter high exhaust borehole vent stacks was conducted. An assessment was made of the current and future /sup 222/Rn emission levels for a group of 27 uranium mines. It is shown that /sup 222/Rn emission rates are increasing from 10 individual operating mines through 1990 by 1.2 to 3.8 times. But for the group of 27 mines as a whole, a reduction of total /sup 222/Rn emissions is predicted due to 17 of the mines being shutdown and sealed. The estimated total /sup 222/Rn emission rate for this group of mines will be 105 Ci/yr by year end 1983 or 70% of the 1978-79 measured rate and 124 Ci/yr by year end 1990 or 83% of the 1978-79 measured rate.

A waterjet mining machine for use in room and pillar mining operations. [Final report
A new mining machine is constructed for use in room and pillar mining operations. This machine uses the action of computer controlled, centrally located high pressure cutting lances to cut deep slots in a coal face. These slots stress relieve the coal ahead of the machine and outline blocks of coal. The movement forward of the machine then wedges up the lower block of coal. This wedging action is assisted by the gathering arms of the loader section of the machine, and by underlying oscillating waterjets which create a slot ahead of the loading wedge as it advances. Finally the top section of coal is brought down by the sequential advance of wedge faced roof support members, again assisted by the waterjet action from the central cutting arms. The machine is designed to overcome major disadvantages of existing room and pillar mining machines in regard to a reduction in respirable dust, the creation of an immediate roof support, and an increase in product size, with concomitant reduction in cleaning costs.

Assessing the land use suitability of mined areas in Appalachia
The Land Use Decision Methodology (LUDM) is a planning framework for mined area land use planning. The LUDM was developed to consider the range of institutional and environmental factors that impact reclamation and land use planning for mined lands. The LUDM was developed as a generalized planning framework rather than a complex/rigid methodology. A matrix that supports the detailed site analysis component of the LUDM was also developed. The matrix has utility for illustrating the impacts that a number of mining related conditions/environmental problems can exert on the environmental feasibility and economics of alternative reclamation plans.

Directional drilling techniques for exploration in-advance of mining
In-seam directionally drilled horizontal boreholes have provided effective solutions in underground coal mines for methane and water drainage and inherently provide an excellent tool for coalbed exploration. Directionally drilled methane drainage boreholes have identified rapid changes in coalbed elevation, coalbed thickness and faults. Specific directional drilling and coring procedures for exploration in-advance of mining are reviewed in this paper, and also other directional drilling applications including in-mine horizontal gob ventilation boreholes, identification of abandoned workings, and water drainage boreholes.

LER Data Mining Pilot Study Final Report
LERs consist of a one page standard form with a standard header and free text data, followed by additional continuation pages of free text data. Currently this LER data is analyzed by first inputting the heading and text data manually into a categorical relational database. The data is then evaluated by enumeration of data in various categories and supplemented by review of individual LERs. This is labor intensive and makes it difficult to relate specific descriptive text to enumerated results. State of the art data mining and visualization technology exists that can eliminate the need for manual categorization, maintain the text relationships within each report, produce the same enumerated results currently available, and provide a tool to support potentially useful additional analysis of the informational content of LERs in a more timely and cost effective manner.

Mining scientific data archives through metadata generation
Data analysis and management tools typically have not supported the documenting of data, so scientists must manually maintain all information pertaining to the context and history of their work. This metadata is critical to effective retrieval and use of the masses of archived data, yet little of it exists on-line or in an accessible format. Exploration of archived legacy data typically proceeds as a laborious process, using commands to navigate through file structures on several machines. This file-at-a-time approach needs to be replaced with a model that represents data as collections of interrelated objects. The tools that support this model must focus attention on data while hiding the complexity of the computational environment. This problem was addressed by developing a tool for exploring large amounts of data in UNIX directories via automatic generation of metadata summaries. This paper describes the model for metadata summaries of collections and the Data Miner tool for interactively traversing directories and automatically generating metadata that serves as a quick overview and index to the archived data. The summaries include thumbnail images as well as links to the data, related directories, and other metadata. Users may personalize the metadata by adding a title and abstract to the summary, which is presented as an HTML page viewed with a World Wide Web browser. We have designed summaries for 3 types of collections of data: contents of a single directory; virtual directories that represent relations between scattered files; and groups of related calculation files. By focusing on the scientists` view of the data mining task, we have developed techniques that assist in the ``detective work `` of mining without requiring knowledge of mundane details about formats and commands. Experiences in working with scientists to design these tools are recounted.

In-situ, Real-Time Monitoring of Mechanical and Chemical Structure Changes in a V2O5 Battery Electrode Using a MEMS Optical Sensor
This work presents the first demonstration of a MEMS optical sensor for in-situ, real-time monitoring of both mechanical and chemical structure evolutions in a V2O5 lithium-ion battery (LIB) cathode during battery operation. A reflective membrane forms one side of a Fabry-Perot (FP) interferometer, while the other side is coated with V2O5 and exposed to electrolyte in a half-cell LIB. Using one microscope and two laser sources, both the induced membrane deflection and the corresponding Raman intensity changes are observed during lithium cycling. Results are in good agreement with the expected mechanical behavior and disorder change of the V2O5 layers, highlighting the significant potential of MEMS as enabling tools for advanced scientific investigations.
