- Coal is mined by two main methods surface or 'opencast' mining and underground mining.
Surface mining, especially mountaintop removal, produces the most environmental damage. Miners and people living in coal mining communities are most at risk for health problems, but air pollution from burning coal affects individuals and ecosystems far removed from the actual power plant.
Surface Coal Mining and Reclamation. Surface coal mining involves disturbing overlying rock layers (overburden) to expose and extract coal reserves using the area mining method wherein the overburden above the uppermost coal seam and the innerburden between the lower coal seams are removed in parallel strips (pits) across the coalfield until the area is mined.
coal mining, physical extraction of coal resources to yield coal; also, the business of exploring for, developing, mining, and transporting coal in any form. Strip mining is the process in which the overburden (earth and rock material overlying the coal) is removed to expose a coal seam or coal bed.
