The impact of mining can be on five components of environment: Land- land surface degradation is the most common impact of mining. Open cast mining is greatly responsible for deforestation of agricultural and forest area. Underground mining leads to weakening of the above surface and thus it limits the use of area for infrastructure.
These physical impacts cause degradation of riparian and aquatic biota and may lead to the undermining of bridges and other structures. Continued extraction may also cause the entire streambed to degrade to the depth of excavation. Sand mining generates extra vehicle traffic, which negatively impairs the environment.
