Impact of Underground Mining on Environment: Environment is affected as a result of underground mining in the following way: (1) Land Damage: Underground mining results in acid mine drainage which causes land damage by subsidence over mined out areas. The abandoned mine pillars undergo deteriorations and failure. Underground mining of coal lowers the surface, breaks and damages the
Get PriceMining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Get PriceA rapid increase in underground mining in a semi-arid area of China has led to serious concerns about the health of vegetation overlying these coal seams. However, there have been no empirical studies to illustrate the response and persistence of surface vegetation in these underground mining areas. A combination of field assessments with remote sensing was used to examine vegetation patterns
Get PriceMining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on

Get PriceThere are many advantages over underground mining, including the fact that it is both more cost-effective and involves less lead time. Highwall mining is also safer than other types of mining, and when, it occurs at the surface, it often produces the same amount of output as mining underground does. Smaller blocks of coal can be accessed with high wall mining, and operations can take place

Get PriceThe impact of mining is leading to the major issues, like a threat to the entire environment and also damaging the health of all life on Earth. Mining procedures generally require a larger and vast area of land. Deforestation is a by-product of mining and the build up of the mining areas requires constructing roads and residences for the mine employees and often vegetation farms are abolished.
