Open Cut and Underground Mining | iMINCO

When minerals and deposits are found close to the surface and spread across a large distance, the best way to mine is to use the open cut mining method. In this process, the area is cleared of all topsoil and vegetation, this material is stockpiled and used later when rehabilitating the area once mining is finished.

Mining Processing. Coal in Wyoming is uncovered and removed by large machines in a process called surface mining. Before the coal can be removed from the ground, the topsoil and dirt above it is removed using scrapers. This soil is usually removed ahead of the pit and carried behind to place on top of reclaimed areas or backfill.

Openpit mining SourceWatch

For minerals that occur deep below the surface—where the overburden is thick—underground mining methods are commonly used. The process begins with the top layers of the land being removed. After that, layer after layer is taken away until the coal is visible. The coal is taken out, processed, and sold.

In room and pillar mining, the most common type of underground coal mining, coal seams are mined by a continuous miner that cuts a network of "rooms" into the seam. As the rooms are cut, the continuous miner simultaneously loads the coal onto a shuttle or ram car, from which it will eventually be placed on a conveyor belt that will move it to the surface.
