Regulation of Coal Strip Mining

domestic coal production was derived from surface mining, up from 19 percent immediately following World War II and 38 percent in 1969. The relative expansion of surface mining has occurred in all regions of the country, but has been most pronounced in the West.

Strip Mining A Destructive Way of Coal Extraction

Mar 12, 2017 Surface or strip mining damages and pollutes ecosystems to a great degree. This is because by definition the process of strip mining involves striping away trees, plants and topsoil so that the coal can be accessed underneath. This means that surface mining destroys mountain tops, landscapes, forests and wildlife habitats.
