Strip mining process is most suitable for fairly flat shallow singleseam coal, lignite and other bedded deposits. The mineral layer is covered by an even thickness of overburden composed of soft topsoil and weathered rocks in succession. The soft and unconsolidated overburden can be stripped and removed either by dragline or shovel to expose a coal seam and certain metallic ores. The ...

· Coal remining occurs on mine lands and coal refuse piles that have been previously mined. Coal preparation plants remove waste material from coal by washing and concentrating. The plants may also sort and screen coal by size, and may crush the coal to facilitate handling and processing. The coal may be stored at several stages in the process of preparation and transport to the final customer.
