Strip Mining
Andrew P. Schissler, in Encyclopedia of Energy, 2004 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.
Ten technologies with the power to transform mining
· Mining is being increasingly carried out underground as open pits near the end of their mining life and new ore bodies are increasingly being identified deep underground. Constructing underground mines with the use of conventional shaft and tunnel boring machines, however, has proved to be technically challenging, expensive and sluggish.

Crushing in Mineral Processing
· In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wearresistant plate/surface.
