  • Surface Coal Mining and Reclamation | ArcNews

    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 minedIn surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting theAppendix E: Coal Mining and Processing Methods | CoalSurface mining is applied to create the majority of the coal within the United states of america mainly because it really is much less highpriced than underground mining Floor mining might be employed if the coal is buried much less than 200 feet underground In surface mining, big machines get rid of the top soil and layers of rock generallySurface mining and underground mining of coal
