Coal Mining and Processing Surface mining can be used when the coal is buried less than 200 feet underground In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replantedThe Mining Process | Introduction | underground COAL,The Mining Process The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc – see Access to Seam from surface section for these terms) Once access has been gained into the coal seam, workings are developed by mining a series of roadways (or " headings ")Coal Mining and Processing - The National Academies Press,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)
