Environmental Risks of Mining

2012-12-11  Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.

12 Environmental Effects of Coal Mining Environment 911

One of the most obvious (albeit perhaps least harmful) environmental effects of coal mining is noise pollution. Coal mining is a loud, day- and night-long process that disrupts the lives of those in the surrounding communities, reduces the quality of life and can go on for decades. #11 Loss Of Wildlife. Coal mining requires a large expanse of
