The Diglake Colliery Disaster (also known as the Audley Colliery Disaster), was a coal-mining disaster at what was Audley Colliery in Bignall End, north Staffordshire, on 14 January 1895. A flood of water rushed into the mine and caused the deaths of 77 miners. Only three bodies were recovered, with efforts to retrieve the dead hampered by floodwater. 73 bodies are still entombed underground.
