Durham Coalfield
The Durham Coalfield is a coalfield in north-east England.[1] 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.[2]
The two contiguous coalfield areas were often referred to as the Durham and Northumberland Coalfield(s) or as the Great Northern Coalfield.[3]

Future developments
[edit | edit source]With the development of modern technology to produce energy and capture carbon dioxide by carbon capture and storage (CCS)[5] there is renewed interest in the exploitation[6] of the Durham Coalfield reserves by underground coal gasification. This is strategically important to local energy-intensive industries, such as the commodity chemical and steel members of the Northeast of England Process Industry Cluster (NEPIC).[7]
