Strip mining Britannica

Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for both techniques consists of vegetation clearing, soil removal, drilling and blasting of

Strip Mining an overview ScienceDirect Topics

Andrew P. Schissler, in Encyclopedia of Energy, 2004. 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.

Environmental justice and coal mining in Appalachia

Early attempts to regulate strip-mining on the state level were largely unsuccessful due to lax enforcement. The Appalachian Group to Save the Land and the People was founded in 1965 to stop surface mining. In 1968, Congress held the first hearings on strip mining. Ken Hechler introduced the first strip-mining abolition bill in Congress in 1971

3 Technologies in Exploration, Mining, and Processing

Strip mining is commonly used for mining coal seams and phosphate beds. In hilly terrain the mining of the overburden and the deposit (usually a coal seam) follows the contour around the hill and into the hillside up to the economic limits; hence it is called contour mining. In dredging, a suction device (an agitator and a slurry pump) or other
