Jan 25, 2018· In case of strip mining, coal seams are reached by removing the surface above them. The surface, which is referred to as overburden, is removed in long strips in this coal mining technique. The overburden taken out from the first strip is deposited outside the mining place. This process is referred to as outofpit dumping. The void resulting ...

process of mining coal

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting ...

Mine Mining Basics Open Cut Coal

Open cut or surface mining in coal is a suitable choice when coal seams are closer to the natural surface. It is an effective method of retrieving a higher proportion of coal when compared to underground mining. The basic process involves: 1) Exploration 2) Geological Modelling 3) Mine Design 4) Top Soil Stripping 5) Drilling Blasting

One of the methods used in underground mining is called room and pillar, and is often used for mining coal. Part of the mine is open to the surface and part of it is underground. The coal face is dug out, but pillars of coal are left behind to keep the tunnels open and support the roof. Machines called continuous miners are used to remove the coal.

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and ...

Mining coal . Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, while others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

process of mining coal

Dec 11, 2018· Coal mining (also called colliery) is the process of extracting coal from the ground’s surface or from deep underground. Coal miners literally raze entire mountain ranges to feed our insurmountable desire for cheap energy. There’s something brutally simple about coal mining.

Coal mining | World Coal Association

Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining …

Appendix E: Coal Mining and Processing Methods | Coal ...

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...
