⛏ Chisnall Hall Colliery

Chisnall Hall Colliery was a coal mine in Coppull in Lancashire, England. It was the largest coal mine on the Lancashire Coalfield north of Wigan. The colliery on Coppull Moor was owned by Pearson and Knowles Coal and Iron Company in 1896 when it employed 135 underground and 48 surface workers. The colliery appeared on maps in 1908 as a coal mine with two shafts and railway sidings connecting its 1.5-mile mineral railway to the London and North Western Railway's West Coast Main Line. In 1930, Pearson & Knowles merged with the Wigan Coal and Iron Company and others and their collieries became the property of the Wigan Coal Corporation. More than 1,000 people were employed there in 1933 and more than 300,000 tonnes of coal were produced annually.
