The Coalbrookdale Coalfield is a coalfield in Shropshire in the English Midlands. It extends from Linley in the south, northwards to the Boundary Fault which runs northeastwards from the vicinity of The Wrekin. Coal-bearing strata are to be found across three synclines; the Donnington, Madeley and Coalport synclines whilst the majority of the coalfield is subject to intense faulting. The Coalfield produced coal from both deep pits and opencasts over a long period starting in Roman times.
