#0183;#32;Research on One Borehole Hydraulic Coal Mining System XIA Bairu, ZENG Xiping, MAO Zhixin School of Engineering and Technology, China University of Geosciences (Beijing), Beijing 100083, China Abstract: The Borehole Hydraulic Coal Mining System (BHCMS) causes fragmentation of coal seams and removes coal slump through a drilled hole using highpressure water jet.
#0183;#32;As borehole magnetic resonance is specifically tuned to sense the fluidfilled structure and coal matrix nanopores only, the accuracy of the measurement is completely unaffected by matrix composition; BMR does not need to be calibrated for coal type, grade or ash content.

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