The Midgeholme Coalfield is a coalfield in Midgeholme,〔http://www.dmm.org.uk/colliery/m039.htm〕 on the border of Cumbria with Northumberland in northern England. It is the largest of a series of small ''coalfields'' along the south side of the Tyne Valley and which are intermediate between the Northumberland and Durham Coalfields to the east and the Cumberland Coalfield to the west. Like the other small coalfields to its east, this small outlier of the Coal Measures here at Midgeholme occurs on the Stublick-Ninety Fathom Fault System, a zone of faults which defines the northern edge of the Alston Block otherwise known as the North Pennines. It is recorded that coal was being mined here in the early seventeenth century and coal trains were being hauled from Midgeholme Colliery along the Brampton Railway by Stephenson's Rocket, the famous locomotive, in the 1830s.〔Michael R. Bailey, John P. Glithero, 2000, ''The engineering and history of Rocket: a survey report'', Science Museum, London〕 The early workings have left a legacy of spoil heaps, bell pits, shafts and adits. There is no current coal production.〔http://www.northumberlandnationalpark.org.uk/understanding/geology/geologicalhistory/carboniferousrocks/carboniferoussuccession/penninecoalmeasuresgroup.htm〕〔British Geological Survey 2007 ''Bedrock geology: UK North'' 1:625,000 scale geological map, BGS, Keyworth, Notts〕 However in January 2014, Northumberland County Council gave planning permission for the open cast extraction of 37,000 tonnes of coal at Halton Lea Gate. 〔 Hexham Courant 10 January 2014 'Villagers admit defeat after 15 years battling opencast'〕 This may open the way for other applications to mine the coalfield. In 1990 a proposal to mine reserves of 60,000 tonnes of good quality coal at Lambley, Northumberland was rejected, but the prospect for a successful application has now changed, since the Planning Inspector allowed the development to proceed at Halton Lea Gate on appeal.〔 The Planning Inspectorate Inquiry 15 May 2012 Decision 7 August 2012 Appeal ref APP/P2935/A/11/2164056 〕 The following coal seams are recognised from the Pennine Lower Coal Measures within this coalfield. The list is organised stratigraphically, with the uppermost seam first:〔Stone P. et al. 2010.
