· Since most coal mining is done underground by digging up the precious rocks, it has a major effect on the lithosphere, the crust and the upper mantle of Earth. Once they make contact with the air and water, acid is produced which contaminates …
· Surface mining – also known as opencast or opencut mining – is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited – 90% or more of the coal can be recovered.

As for mining processes, they are quite variable. The most productive underground method is known as longwall. A block of coal 200 to 300 meters wide and up to 10 kilometers long is defined by a set of tunnels. A cutting machine is then employed to cut the coal which is removed by conveyers.

· Process And Machinery Required To Extract The Openpit mining WikipediaOpenpit, opencast or open Process And Machinery Required To Extract The Mineral From The Lithosphere cut mining is a surface mining technique of extracting rock or minerals .
The underground method is suitable for extraction of deeper coal seams, whereas opencast method is suitable for shallow coal seams. However, due to less production cost, mechanisation, and less wastage, opencast method dominates in India (93.26% of the total production in the financial year 2016-17).
Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when:
mining - mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on …
Underground coal mining is more common east of the Mississippi River, particularly in Appalachia. Some of the largest underground coal mines, each producing around 10 million tons annually, are located in Pennsylvania and West ia. The largest underground

Underground mining in perspective. Paul Daniel, [email protected] Dr Nicola Careddu, [email protected] . Building stone has been extracted from underground in certain parts of Europe for centuries. In the 20th century, stricter legislation has sometimes restricted opencast quarrying with the result that under favourable geological ...
What is the difference between opencast mining and shaft mining. In open cast miniing the earth surface is simly dug out to take minerals which are shallow shaft mining we should put bores to take minerals which are deep under the earth. Read more.
Open cast mining is the removal of rocks or sediments that contains minerals, with economically important elements. The advantages of open cast mining: • More cost effective, than shaft mining. • The working conditions are safe for miners, there is no risk of toxic gases or cave ins.

Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth''s surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal …

underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required. In ...
Mining of coal is undertaken broadly using two methods: surface and underground. In the case of underground mining, losses are high compared with those of opencast mining; the main causes of these losses are enumerated in the following subsections. 3.6.4.1
Open pit mining has far larger impacts on the environment than underground mining. Open pits are giant holes in the ground, while underground mines mostly impact what''s underground. For an open pit, vast amounts of rock with no value is removed, usually it''s about 3 to 10 times the amount of the ore that is processed.

Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes. The mineral exposed is completely extracted.
