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.
Hydraulic Coal Mining the underground working of coal deposits in which the coal is excavated transported and lifted to the surface by using the energy of a water jet. The source is usually underground water flowing into the mine. The first experimental operations with hydraulic coal mining were carried out in 1935-36 by V. S. Muchnik in the Kizel
Coal structure directly correlates to permeability and hydraulic fracturing effects. Underground coal mining indi es that a single coal section generally contains multiple coal structures in superposition making how to recognise the coal structure combination and predict its influence on coal permeability a challenging problem. Based on well-drilling sampled cores the geological strength

T ypical example s of this type of mining are the larger tonna ge coal mining operations in Mpumulanga. Favour able conditions are: Relatively thin overburden 0- 50 m maximu m otherwise stripping
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 developed from ancient Roman techniques that used water to excavate soft underground deposits.
According to the method in the process of removing the hydraulic support 1 for solid filling coal mining the roof of the support removing space of the work surface is stable so that the hydraulic supports on the work surface of solid filling coal mining are ensured to be safely and efficiently removed and meanwhile it is guaranteed that the moving of overlying strata on the finishing cut
