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

In-situ leach mining involves pumping of a lixiviant into the ore body via a borehole, which circulates through the porous rock dissolving the ore and is extracted via a second borehole. The lixiviant varies according to the ore deposit: for salt deposits the leachate can be fresh water into which salts can readily dissolve.
The British sinologist and historian Michael Loewe states that borehole sites could reach as deep as 600 metres (2,000 ft). [3] K.S. Tom describes the drilling process: "The Chinese method of deep drilling was accomplished by a team of men jumping on and off a beam to impact the drilling bit while the boring tool was rotated by buffalo and oxen."
Shaft mining, mining vertically; Slope mining, mining at an inclined angle Stoping is the process of extracting out the ore from underground, leaving a hole called a stope; Room and pillar; Longwall mining; Retreat mining; Fire-setting, a method used in stoping by setting fires to timber and letting the resulting collapse break up the rock
Borehole drilling has a long history. Han dynasty China (202 BC – 220 AD) used deep borehole drilling for mining and other projects. Chinese borehole sites could reach as deep as 600 m (2,000 ft). [1]
The Hard Rock Miner's Handbook is a reference book that deals with the underground hard-rock mining industry. It was written by engineer Jack de la Vergne as a non-profit publication. [1] The first edition was published in 2000 by McIntosh Engineering, a mining engineering consulting company. [2]
There are two principal phases of underground mining: development mining and production mining. Development mining is composed of excavation almost entirely in (non-valuable) waste rock in order to gain access to the orebody. There are six steps in development mining: remove previously blasted material (muck out round), scaling (removing any unstable slabs of rock hanging from the roof and ...
