Consequences of Coal Mining in India’ during November 19-21, 2007 at New Delhi. including soil erosion, dust, noise and water pollution, and impacts on local biodiversity. Mine subsidence can be a problem with underground coal mining, whereby the ground level lowers as a result of coal having been mined beneath. Steps are taken in modern mining operations to minimise these impacts. Good
Land Degradation . The surface coal mining operations and all their associated activities degrade the land to considerable limits. The land damage caused due to coal mining was studied. 70 Large areas of land are excavated during open cast mining operations in order to extract mineral ore. 59 Significant amounts of forest is lost along with the rich top soil during pre-mining overburden

Soil is the earth’s fragile skin that anchors all life on Earth. It is comprised of countless species that create a dynamic and complex ecosystem and is among the most precious resources to humans. Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. The transition to agriculture from natural vegetation often cannot
Mining leads to a massive habitat loss for a diversity of flora and fauna ranging from soil microorganisms to large mammals. Endemic species are most severely affected since even the slightest disruptions in their habitat can result in extinction or put them at high risk of being wiped out. Toxins released through mining can wipe out entire populations of sensitive species.
Due to the surface mining at Makrana, the flora, hydrological relations and soil biological systems are drastically disturbed. In Makrana the main cause of environmental pollution is marble mining dust particulates and stone crusher dust. Analysis of the samples showed that the soil of Makrana is saline sodic because of high pH value and excess sodium presence. The agricultural field near
Although soil erosion is a natural process, human activities have greatly accelerated it. The agents of soil erosion are the same as of other types of erosion: water, ice, wind, and gravity. Soil erosion is more likely where the ground has been disturbed by agriculture, grazing animals, logging, mining, construction, and recreational activities.
22.07.2012· Costa Rica loses about 860 million tons of valuable topsoil every year, while the Great Red Island, Madagascar, loses so much soil to erosion (400 tons/ha) that its rivers run blood-red, staining the surrounding Indian Ocean.

Mining operations with degradation of the land largely . contribute to the corrosion of soil—a phenomenon that can. be seen more in the surface mining activities (Sengupta. 1993). Mine waste can
Active acidity (or soil-water pH) is due to the presence of H+ ions in the soil solution. Active acidity will indicate a need for lime. Potential acidity (or buffer pH) is the amount of Al3+ and H+ ions that are adsorbed on soil particles (negatively charged cation exchange sites) and can be desorbed from these exchange sites to the soil solution (buffering the soil) when liming materials are
