1 Mining Methods Traditional mining methods fall into two broad categories based on locale: surface or underground. 1) Surface mining: includes i) Mechanical excavation methods; such as Open-pit and Strip mining. ii) Aqueous methods; such as placer and solution mining. 2) Underground mining: is usually classified in three categories of methods: ...Get Price
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.Get Price
mining - mining - Surface mining: It has been estimated that more than two-thirds of the world’s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.Get Price

Strip mining is a mineral-extraction process in which a layer or seam of undesired material (called “overburden”) is removed from the surface of an area to allow efficient access to a desired material existing underneath the layer being stripped. As the process suggests, it is a form of surface mining, and it is primarily used to extract ...Get Price
