Borehole Mining, Underground Mining, Mining Techniques

2021-7-15  Borehole mining consists of two pipes one for pumping down high pressure water and another that delivers slurry back to the surface. A BHM tool consists of water jet pump, hydro monitor section, an extension section and a hub. The tool is lowered into a well until the hydro monitor reaches the depth of the hole where the borehole mining is started.

Applications of Geomatics in Surface Mining IOPscience

2017-12-1  In terms of method of extracting mineral from deposit, mining can be classified into: surface, underground, and borehole mining. Surface mining is a form of mining, in which the soil and the rock covering the mineral deposits are removed. Types of surface mining include mainly strip and open-cast methods, as well as quarrying.

Borehole mining SpringerLink

Borehole mining is a general term for any process in which the wanted mineral or metal values of a deposit are fluidized in place by some means and removed from the deposit via borehole. Researchers have proposed (Shock and Conley, 1974; Anon., 1974a) that it should supplant the accepted, but narrower, term chemical mining, which implies that the wanted values are dissolved in a reagent that

Hydraulic borehole mining for pitching coal seams. Final

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.
