What are the environmental impacts of mining?

2020-4-6  What are the environmental impacts of mining? Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.

How Does Mining Affect the Environment?

2016-12-3  Different types of mining have various impacts on land. For example, strip mining results in the clearing of trees, plants and topsoil [2]. One effect of this type of mining on the environment is the pervasive problem of soil erosion, which in turn leads to the pollution of waterways.. Another destructive type of mining is underground coal mining.

Underground mining has severe environmental impacts

New geologic studies suggest that underground mining of coal may cause more environmental damage over long periods of time than surface strip mining followed by proper reclamation, according to the U.S. Geological Survey (USGS). While underground mining initially disturbs only a small portion of the surface above a mined area, long-term effects
