SURFACE MINING Surface mining is done by removing(stripping) surface vegetation, dirt,and if necessary, layers of bedrock inorder to reach buried ore deposits.

Throughout history, coal has been a useful resource, It is thelargest source of energy for the generation of electricityworldwide, and is also used for industrial purposes, such asrefining metals.USES OF COALINDUSTRY DOMESTIC
Air Quality Water Pollution Noise Pollution Impact on Land
Large scale excavation. Removal of topsoil. Dumping of solid wastes. Creation of derelict land. Subsidence. Noise and vibrations.
Rapid population growth and skyrocketing demand forenergy. 70% of coal consumption expected to be in electric powersector. In 2003, coal-fired power plants consumed 5.0 quadrillion Btuof coal, representing 69% of India’s total coal demand. Coal-fired generating capacity projected to increase from 67GW in 2003 to 161 GW in 2030.
