The presence of pyrite (FeS2) in coal can cause or contribute to several problems for the coal mining industry. These problems, which include spontaneous combustion, roof falls, floor heave, and accidental explosions in coal surface mining when ammonium nitrate-fuel oil (ANFO) explosives are used, result from pyrite oxidation.

An example would be Acid Mine Drainage. Acidic water can flow out of abandoned coal mines. Mining has xposed rocks which contain the sulphur-bearing mineral, Pyrite. This mineral reacts to air and water to form sulphuric acid. When it rains, the diluted acid gets into rivers and streams and can even seep into underground sources of water.
