Stability of a coal pillar for strip mining based on an elastic

2016-9-1  At present, the mining methods under “three-body” are strip mining, backfilling mining method, room and pillar mining, grouting of bed separations, harmonic mining, etc. 1 As for strip mining, coal reserve is divided into regular strips that are mined one in every other strip. The strips left behind, called strip pillars, are designed to

The research results show that in the process of strip-filling bodies replacing coal pillars the strip-filling bodies work as bridge piers. The supporting strength, size and filling methods are designed reasonably to control the movement range of the key layers and to realize the steady transferring of mine ground pressure and effective control of overlying strata’s movement.

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.
