inserts a rectangular pushbeam (screw-conveyor segment) into the center section of the machine between the Powerhead and the cutterhead. The pushbeam system can penetrate nearly (proven in 2015 till today) into the coal seam. One patented highwall mining system uses augers enclosed inside the pushbeam that prevent the mined coal from being contaminated by rock debris during the conveyance process. Using a video imaging and/or a gamma-ray sensor and/or other geo-radar systems like a coal-rock interface detection sensor (CID), the operator can see ahead projection of the seam-rock interface and guide the continuous miner's progress. Highwall mining can produce thousands of tons of coal in contour-strip operations with narrow benches, previously mined areas, trench mine applications, and steep-dip seams by utilizing a controlled water-inflow pump system and/or a gas (inert) venting system. Recovery with tunneling shape of drives used by highwall miners is much better than round augering holes, but the mapping of areas that have been developed by a highwall miner are not mapped as rigorously as deep mined areas. Very little soil is displaced in contrast with mountaintop removal; however, it is comparatively more expensive to own and operate a highwall miner. Mapping of the outcrop, as well as core hole data and samples taken during the bench-making process, are taken into account to best project the panels that the highwall miner will cut. Obstacles that could be potentially damaged by subsidence and the natural contour of the highwall mine are taken into account, and a surveyor points the highwall miner in a line (theoretical survey plot-line) mostly perpendicular to the highwall. parallel lines represent the drive cut into the mountain (up to deep (2015 records), without heading or corrective steering actuation on a navigation azimuth during mining results in missing a portion of the coal seam and is a potential danger of cutting in pillars from previous mined drives due to horizontal drift (roll) of the pushbeam-cuttermodule string. Recently highwall miners have penetrated more than (2015 ongoing records into the coal seam, and today's models are capable of going farther, with the support of gyro navigation and not limited anymore by the amount of cable stored on the machine. The maximum depth would be determined by the stress of further penetration and associated specific-power draw (torsion and tension in screw transporters string), but today's optimized screw-transporters conveying embodiments (called pushbeams) with visual product development and discrete element
