surface by the Eductor. In a collecting pond or tank, the slurry is separated and clarified water is re-circulated. While extracting rocks and ores, different-shaped caverns can be created. Their shape depends on the BHM tool manipulation while mining which obviously consist of the tool rotation, sliding it up and down and combination of these two. Borehole mining is applied from vertical, horizontal and deviated wells. Advantages of BHM The main advantages of the method include its low capital and operating cost, mobility, selectivity, ability to work in hazardous and dangerous conditions, low environmental impact and several more. The method is used in mining of such natural resources and industrial materials as: uranium, iron ore, quartz sand, fine gravel, coal, poly-metallic ores, phosphate, gold, diamonds, manganese, rare earths, phosphate, amber and several more. Borehole mining is also used in exploration, oil, gas and water stimulation, underground storage construction, environmental applications and a few more.
