Bergwerk Saar

The Duhamel shaft at Bergwerk Saar in Ensdorf was sunk to depth 868 metres in 1913. At the end of June 2012 the colliery closed, marking the end of hard coal mining in the Saarland after several centuries. At closure this shaft was being used for men and materials handling and was wound by a steam engine manufactured by Dingler'sche Maschinenfabrik in 1918.
