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.

Can biochar reclaim coal mine spoil? ScienceDirect

2020-10-15  1. Introduction. Surface coal mining activities completely destroy vegetation cover, soil and biodiversity. These post-mining fallow lands are degraded, devoid of the basic pedological properties and are potential source of contamination (Frouz et al., 2008).Mining industry is temporary user of land unlike other industries, so there are ample opportunities to reclaim mine degraded land to
