Coal mining Coal mining Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic
There are several different ways to mine underground. You can build spiral tunnels that circle the deposit, sink vertical shafts adjacent to the ore, or create adits, which are horizontal excavations into the side of a hill or mountain. Unlike open pit, underground mining requires that you take into account a wide variety of added requirements

Coal is mined by two methods: s urface or ‘opencast’ mining or underground or ‘deep’ mining. The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.

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 exploited. This equipment can include the following: Draglines which
Coal is mined either by surface methods (open-cut or open-cast mining) or by underground techniques. In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 ).
Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities

Open Pit vs. Underground Mining Methods While most mineral deposits can be mined by either surface or underground methods, employee-hours for underground US coal mines in the last decade is three to four times higher than for surface mines. The difference between the injury rates per one million tons of coal production further demonstrates this point underground mining is less
