    Types of Surface Mining American Mine Services

    This type of mining makes sense when the mineral is near the surface. If the ore is too far under the surface, the process of strip mining becomes impractical and needlessly damaging to the terrain. Two types of strip mining exist, depending on the amount of ore under the surface, and the surrounding terrain. They are
