    What Are the Pros and Cons of Strip Mining with pictures

    Andrea Cross Strip mining is used to recover resources that are close to the surface. Strip mining is a form of surface mining that is usually employed for the recovery of materials such as coal and tar sand, which are relatively near the surface of the earth. Surface vegetation, soil, and rocks are removed in strips, often in conjunction with controlled explosions, to make removal more efficient.
