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

Strip mining is considered very harmful to the environment. Proponents of strip mining cite its better efficiency, cost, and safety as compared with traditional underground mining techniques. The recovery rate of materials is higher with strip mining, with approximately 80% to 90% of the material being recovered, as opposed to only approximately 50% with tunnel mining.

An Introduction To Surface Mining

Strip Mining. Strip mining is the process of removing a thin strip of overburden above the deposit and then dumping the waste behind it; continuing along the length of the deposit. Once the resource under this strip has been exploited, another parallel strip is started, with the waste dumped on top of the first strip

Plundering Appalachia - The Tragedy of Mountaintop

2010-7-16  Mountaintop removal is strip-mining on steroids. Massive dump trucks, huge bulldozers, and ten-story-high draglines can undo in months what geological processes took millions of years to build. Typically, multiple coal seams are exposed as a mountaintop-removal operation dismantles the landscape, piece by piece.
