chemical reactions in coal mining

Surface and groundwaters associated with mines are often affected by acidification. Acid mine drainage AMD is recognised as one of the most important environmental side effects of mining. Coal mines can have the most severe acidification problems, as some coal seams contain pyrite, which has high concentrations of sulphur.

    Pyrite problems in the coal mining industry

    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 nitratefuel oil ANFO explosives are used, result from pyrite oxidation. Pyrite oxidizes exothermically in the presence of air and moisture to f
