Coal mining legacy problems

Coal mining problems

Potential problems can include:

  • collapse of shallow coal mine workings
  • collapse of, or risk of entry into, mine entries (shafts and adits)
  • gas emissions from coal mines including methane and carbon dioxide
  • spontaneous combustion or ignition of coal which may lead to the production of carbon monoxide
  • transmission of gases into adjacent properties from underground sources through ground fractures
  • coal mining subsidence
  • water emissions from coal mine workings
