Jan 12, 2021 There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.

Dec 04, 2019 Strip mining is done only when the ore body is in close proximity to the surface. Open-pit mining Open-pit mining is the method in which minerals or rocks are extracted from the Earth via an open pit or borrow. Mountaintop removal mining Mountaintop removal mining (MTR) is done by mining coal seams underneath mountaintops. This method is often considered safer, as well, and doesnt require extensive electricity rigging and water piping. Strip Mining.

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 environments. the mining technologies currently in use on Federal leases and the potential for commer-cial mining technologies to extract Federal coal reserves from deep underground seams.
