An Introduction To Surface Mining

There are 5 main types of surface mining, which are used in various degrees and for different resources. These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource.
