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.

Fracture Mechanics Of Mining Dragline Booms

· The Australian coal mining industry operates a large dragline fleet such as is shown in Figure 1. The draglines generally work 24 hours a day, 364 days a year. The productivity of each dragline is generally estimated to be around $8000/hour and thus the cost of any unscheduled down time is very significant for the operation.
