Mosley Common Colliery was a coal mine originally owned by the Bridgewater Trustees operating on the Manchester Coalfield after 1866 in Mosley Common, Greater Manchester, then in the historic county of Lancashire, England.[1] The colliery eventually had five shafts and became the largest colliery on the Lancashire Coalfield with access to around 270 million tons of coal under the Permian rocks to the south.[2]
