Hydraulic Mining - an overview ScienceDirect Topics

CHARLES SIMEONS M.A., in Coal: its Role in Tomorrow's Technology, 1978. Hydraulic Cutting. This method has been described earlier under hydraulic mining, applicable to soft coals and those such as in Germany which are not easily accessible, or form steep seams.It has been practised in many countries – with particular success in some. In most instances pressures have been less than 5000 psi.

Hydraulic borehole mining for pitching coal seams. Final ...

2 天前  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.
