    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 the coal; (6) processing the coalLongwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates, feasible only in relatively flatlying, thick, and uniform coal beds A highpowered cutting machine (the shearer) is passed across the exposed face of coal, shearing away broken coal, which is continuously hauled away by a floorlevel conveyor system (Appendix E: Coal Mining and Processing Methods | CoalCoal mining is the process of locating and removing underground coal depositsThe coal mining industry refers to the publicly and privately owned companies in various countries that are involved in this processSurface mining, most commonly in the form of socalled strip mining, and underground mining, when tunnels are dug far below the surface, are the twoVarious Process Of Coal Mining
