4 Coal Mining and Processing Coal: Research and

2021-5-6  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 coal if necessary; and (7) decommissioning the mine and releasing the property for post-mining use.

What is the process of mining coal? AskingLot

Coal Mining and Processing. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.
