(BHM) (also referred to as jet-boring) is a remote operated method of extracting (mining) mineral resources through boreholes by means of high pressure water jets. This process can be carried-out from land surface, open pit floor,underground mine or floating platform or vessel through pre-drilled boreholes.
Advantages of BHM
The main advantages of BHM include its low capital cost, mobility, selectivity, ability to work in hazardous and dangerous conditions and low environmental impact. The method has been used in mining of such natural resources and industrial materials as: uranium, iron ore, quartz sand, gravel, coal, poly-metallic ores, phosphate, gold, diamonds, rare earths,amber and several more. Borehole mining is also used in exploration, oil, gas and water stimulation, underground storage construction and drainage.
