Environmental Impact from Mining and Drilling - DustWatch CC

16/04/2020  Unfortunately, this strip or open-cast mining can have a significant impact on the ecosystem. When a strip mining operation occurs, the biologic life on the surface of the rock body is virtually eliminated. This loss of vegetation can cause soil erosion, especially in forested areas, since there's no vegetation to stabilize the rock layer.
