What are the main methods of mining? American

There are four main mining methods underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other

Uranium How is it Mined?

Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft).

Room and Pillar Mining an overview ScienceDirect Topics

Long wall mining is a mostly automated process whereby long-wall mining machines are used to extract blocks of deposits as wide as the face of the equipment, and potentially kilometers long. Cutters are then used to cut the deposits from the face of the equipment. Room and pillar mining is a common underground mining method for mining oil shale.

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper- uranium mines can reach 6,500 feet, or 2 kilometers.
