Pros and Cons of Strip Mining APECSEC

25-02-2015  2. Strip Mining Is Faster. Most other mining techniques require the digging of tunnels, which adds additional time to the process. Strip mining does not rely on the digging of tunnels and since the route to the surface is much shorter, this also cuts down on the amount of time spent.

What Are the Pros and Cons of Strip Mining? (with pictures)

Strip mining is safer for workers than tunnel mining. The cost of mining with this method is also lower. This helps to defray production costs and thus, theoretically, the final cost of the material. Strip mining is also safer than underground mining, which can be hazardous due to collapsing tunnels and toxic air.

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.
