Selby Coalfield

Selby coalfield (also known as the Selby complex, or Selby 'superpit') was a large scale deep underground mine complex based around Selby, North Yorkshire, England, with pitheads at Wistow Mine, Stillingfleet Mine, Riccall Mine, North Selby Mine, Whitemoor Mine and at Gascoigne Wood Mine; all coal was brought to the surface and treated at Gascoigne Wood, being distributed onwards by rail. The primary purpose of the pit was to supply coal for electrical power generation; much of it was used in the nearby Aire valley power stations.

Mining peaked in 1993–4 at 12 million tonnes. The mines were acquired by RJB Mining in 1997 after the privatisation of the coal industry; loss of subsidy, geological problems, and low UK coal prices made the pits unprofitable by the 21st century. Closure was announced in 2002, and mining completely ceased by 2004.
