Borehole mining tool and technology principle schematic. 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 ...
Soft ground drilling can be undertaken using a rotary auger or wash boring techniques, while rock drilling often use methods such as NMLC which allow for recovery of a core of material which can be examined to determine the strength, degree of weathering, understanding of any how intact the rock is and identify any discontinuities or other ...
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 hammer and pick, two basic tools traditionally used in mining for breaking rock, together form a main heraldic symbol of mining and miners. It is also used to mark the location of mines on maps. In other locations, the pickaxe and shovel fill the same purpose. The following outline is provided as an overview of and topical guide to mining:
The U.S. now ranks second to last in the time it takes to develop a new mine—roughly 29 years. Only Zambia is worse.
44% of mining facilities in the United States are located in forests. Large-scale mining in areas of Latin America, like Brazil, release pollutants detrimental to neighboring rainforests. [38] Copper mining efforts in the Carajas Mineral Province in Brazil result in 6,100 km of deforestation every year. [38]
