Possibly one of the scariest environmental effects of coal mining is the threat of acid rain. The high acidity of AMD remains in the water supply even through evaporation and condensation, which enables it to stay in the atmosphere and eventually return in the form of "acid rain," thus perpetuating the cycle of pollution. #2 Radiation

Coal Mining and the Environment: Surface Coal Extraction In open pit mining, the "overburden" or the soil over the coal seem is taken away. Then heavy equipment is used to remove the coal. In mountaintop removal, the top part of a mountain is removed and the coal is taken after that. This has been commonly used in Appalachia. Surface mining is less dangerous for miners than underground mining ...

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
Coal mining | World Coal Association
In room-and-pillar mining, coal deposits are mined by cutting a network of rooms into the coal seam and leaving behind pillars of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam - although this coal can sometimes be recovered at a later stage.
