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:

What Is Subsurface Mining?

 · Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and require the drilling of vertical or horizontal shafts for access. The shafts are reinforced with supports before workers access the tunnels.

Coal Types, Formation and Methods of Mining

When retreat mining is completed, the mined area is abandoned. There are two types of room and pillar mining–conventional mining and continuous mining. Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars.
