When coal seams are near the surface it may be economical to extract the coal using open cut also referred to as open cast open pit mountaintop removal or strip mining methods opencast coal mining recovers a greater proportion of the coal deposit than underground methods as more of the coal seams in the strata may be exploitedWhen coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploitedMar 25, 2018 While surface mining is used for coal that can be found anywhere from the surface to 200 feet below, underground mining is used for coal that is located lower. In surface mining, the top layer is removed which may include plants, soil rocks. This exposes the coal below the top layer. It is then excavated out. Once all the coal has been removing ...

Coal wash plant in Clay County, Kentucky. Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. 6 In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof.

Coal mining - Wikipedia, the free encyclopedia. The goal of coal mining is to obtain coal and sometimes other resources from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely ...
The opencast coal mining technique is used in areas were the coal reserves are scattered in shallow and thin seams and cannot be extracted by deep mining methods (Beynon et al., 2000). The opencast process starts with exploration activities to identify where there are deposits of coalThe E, A, and AU coal seams in the West block are amenable for open-cast mining. Shallow underground mining method involving drill and blast operations will be carried out to extract the G and K coal seams at a later stage. The extracted coal from the mine will be processed at an on-site single-stage wash plant, which will use dense medium ...Opencast mining for coal as we know it today started in 1942 as a wartime expedient. To boost vitally needed coal output, surface mining became the responsibility of the Mines Department of the Board of Trade and was carried on by the Ministry of Works until 1945, then by the Ministry of Fuel and Power.
