South Yorkshire Coalfield

The South Yorkshire Coalfield is defined by a triangle lying between Barnsley, Doncaster and Sheffield, though a few mines within the coalfield lie outside this area. It is part of the larger Midland coal field which stretches from Nottingham in the south to Bradford and Leeds in the north. Its western boundary is defined by the outcropping of the coal seams in the foothills of the Pennines and in the east by the descent of the coal-bearing strata under overlying rocks as they approach the North Sea.

Since the creation of the county of South Yorkshire the name can be somewhat misleading as the coalfield itself stretches into much of West Yorkshire and parts of North Yorkshire.
