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 ...

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
Electric discharge – The methods utilizing electric discharge are based on long-term experience gained in other application areas. Electrical plasma – is based on crushing by irradiation of plasma with high temperature up to 20 000°C
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."
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 ...
A drilling rig is used to create a borehole or well (also called a wellbore) in the earth's sub-surface, for example in order to extract natural resources such as gas or oil. During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of ...
