Hydraulic borehole mining (Conference) OSTI.GOV

The borehole hydraulic coal mining system accesses the coal seam through a hole drilled in the overburden. The mining device is lowered through the hole into the coal seam where it fragments the coal with high-pressure water jets. The fragmented coal is pumped to the surface as a slurry by a jet pump located in the center of the mining device.

Borehole Mining - Kinley Exploration : Kinley Exploration

Borehole Mining No longer a science project, borehole mining is proving itself as a workable technology that can be applied to a number of industries. Hydraulically jet-cutting a cavern of rock 20 feet in diameter from a drilled bore hole allows this system to recover resources previously uneconomical for open pit or underground mining operations.

Borehole mining - Wikipedia

Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking).This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre-drilled boreholes.
