The Cannock Chase Coalfield lies just to the north of the South Staffordshire Coalfield, from which it is separated by the Bentley Fault. The seams under Cannock Chase are much deeper than those in South Staffordshire, being around 1,600 feet (490 m) near Rugeley, compared to around 800 feet (240 m) in South Staffordshire.[2]
By 1890, the coalfield was producing 3 million tons of coal per year,[2] and by 1933 this had risen to over 5 million tons.[3]
Historical records of Cannock Chase Colliery Company Limited, established in 1859, are held at the Cadbury Research Library (University of Birmingham).[5]
