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

    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.
