Prospecting is the first stage of the geological analysis (second – exploration) of a territory. It is the physical search for minerals, fossils, precious metals or mineral specimens, and is also known as fossicking.. Prospecting is a smallscale form of mineral exploration which is an organised, large scale effort undertaken by commercial mineral companies to find commercially viable ore ...
May 17, 2019· (b) The state should also promote the application of CBM exploration and the development of advanced techniques, to improve multiusage techniques, such as surface drainage technology, depressure drainage at coal mines, and the reuse of wells in goaf areas to provide preliminary guidance to decrease the difficulties of the CBM industry.
technology in coal exploration. The geophysical well logging techniques provide detailed records of lithological units encountered in the boreholes, thus identifying the coal seams and thickness of each horizon correlation is useful; in coal exploration or related formation, which continues to be present in
Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th

Most advanced exploration for coal and minerals uses a combination of diamond and reverse circulation drilling. RC drilling is similar to water bore drilling and the latest rigs are mounted on a 4WD vehicle Diamond drilling produces core of rock which is logged by a geologist with samples sent to a laboratory for analysis
Moreover, the coming up of new coal mines in the occurrences verified the probability of potential targets and calls for systematic exploration. With this informative Newera has vested its potential and resource in looking for potential sites that can be systematically explored with the aid of advanced techniques.

Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties.
(1) exploration, (2) well development, (3) production, and (4) site abandonment. Exploration involves the search for rock formations associated with oil or natural gas deposits, and involves geophysical prospecting and/or exploratory drilling.. Well development occurs after exploration has located an economically recoverable field, and involves the construction of one or more wells from the ...
