Hydraulic mining method (Patent) | 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.

Hydraulic mining - Wikipedia

Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining originated out of ancient Roman techniques that used water to excavate soft underground ...

Hydraulic Mining - an overview | ScienceDirect Topics

Hydraulic mining is also likely to find good application with our friable and moderately soft coals. The advantages of hydraulic mining are – winning of coal is not hindered by bringing of face support, the system is not very sophisticated to warrant complexity of adoption, higher output per working face results with steeply inclined seams.
