assessing the environmental impacts of coal mining

hard to assign economic values to all socio-economic impacts from UG and OC mining. This paper provides a methodology for comparison of the social and economic costs of UG and OC mining. Section 2 of this paper presents an overview of some potential impacts of coal mining on environmental, social and economic systems focusing on UG and OC mining.

Environmental impact assessment (EIA) is carried out to assess the effects of any project/activity on the environment. In a typical coal mining area, the mining activities disturb the flora and fauna of the region. Thus, air, water, soil, topography, land-use/land-cover (LULC) including vegetation patterns are affected severely. To assess the

Air quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining.

environmental consequences of open pit mining

Disadvantages of open pit mining. One of the main disadvantages of this type of mining operation is the environmental impact it causes. Since cyanide, mercury and sulfuric acid are used to remove the wastewater, groundwater and air are contaminated as toxic dust . This is absorbed by animals and plants.
