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 ...
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
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
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] Mining also results in a loss of biodiversity. Deforestation as well as the release of toxic chemicals to ...
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.
A water resources borehole into the chalk aquifer under the North Downs, England at Albury. Engineers and environmental consultants use the term borehole to collectively describe all of the various types of holes drilled as part of a geotechnical investigation or environmental site assessment (a so-called Phase II ESA).
Tricone rock bit. Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.
