Mountaintop Removal 101 Appalachian Voices

What is the process of mountaintop removal coal mining? CLEARING. Before mining can begin, all topsoil and vegetation must be removed. Because coal companies frequently are responding to short-term fluctuations in the price of coal, the trees are often not used commercially, but instead are burned or sometimes illegally dumped into valleys.

Strip Mining A Destructive Way of Coal Extraction

Mar 12, 2017The process of strip mining also lowers groundwater levels around the mine. In order to remove the coal, vast quantities of groundwater are pumped out of the mine and as a result, surrounding ecosystems and farmland may become drier, and erosion may start to change the landscape. Strip mining also uses significant amount of water to suppress dust.
