Negative Effects of Coal Mining The World Counts

The effects of mining coal on the environment. There are 2 ways to mine coal Strip Mining and Underground Mining both ways have their own impact to the environment and health. We know it but coal is such a cheap energy source that we don’t want to let go of it. The negative effects of coal mining cannot be disputed:get price

How Does Coal Mining Affect the Environment? Reference

Coal mining affects the environment in several ways: underground coal mining introduces toxins such as methane gas into waterways and the atmosphere, and surface coal mining contributes to deforestation and erosion. Coal mining displaces large amounts of water, which in turn alters local water tables.get price

12 Environmental Effects of Coal Mining Environment 911

EnvironmentCausesEffectsSafetyToxicityOne 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. Another environmental effect of coal mining is \"mine subsidence\" -- the earth sinking as a result of a disturbance to its foundation. This occurs when the coal deep below our planet's surface is rem

Environmental impact of the coal industry Wikipedia
