Chemical mining of coal to avoid stripping. Full Record; Other Related Research; Abstract. If steamoxygen mixtures replace the more customary air or oxygen feed gases for underground coal gasiflcation, then the coal energy can be recovered with minimal enviromnental damage. Such chemical mining looks like an attractive alternative to strip mining. (auth) Authors: Elliott, G Publication

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. Sulphuric acid mine runoff can be produced when pyrite is exposed to water and oxygen,, acid mine drainage. This can have severe detrimental effects

Coal is burned in the presence of atmospheric oxygen. This increased temperature allows a chemical reaction between the fuel (carbon in the coal) and the oxygen in the atmosphere to occur which forms Carbon dioxide (CO 2). Since coal also contains hydrogen atoms the combustion will form some water vapour as a product (H 2 O).
