Durham Coalfield

The Durham Coalfield is a coalfield in north-east England. It is continuous with the Northumberland Coalfield to its north. It extends from Bishop Auckland in the south to the boundary with the county of Northumberland along the River Tyne in the north, beyond which is the Northumberland Coalfield.

The two contiguous coalfield areas were often referred to as the Durham and Northumberland Coalfield(s) or as the Great Northern Coalfield.
