Coal mining in the United Kingdom dates back to Roman times and occurred in many different parts of the country. Britain's coalfields are associated with Northumberland and Durham, North and South Wales, Yorkshire, the Scottish Central Belt, Lancashire, Cumbria, the East and West Midlands and Kent. After 1970, coal mining quickly collapsed and practically disappeared in the 21st century.[1] The consumption of coal – mostly for electricity – fell from 157 million tonnes in 1970 to 18 million tonnes in 2016. Of the coal mined, 77% of supplies were imported[2] from Colombia, Russia and the United States. Of the coal mined in the UK in 2016 all was from open-cast coal mines. Employment in coal mines fell from a peak of 1,191,000 in 1920 to 695,000 in 1956, 247,000 in 1976, 44,000 in 1993, and to 2,000 in 2015.[3]
Almost all onshore coal resources in the UK occur in rocks of the Carboniferous age, some of which extend under the North Sea. Bituminous coal is present in most of Britain's coalfields and is 86% to 88% carbon. In Northern Ireland, there are extensive deposits of lignite which is less energy-dense based on oxidation (combustion) at ordinary combustion temperatures (i.e. for the oxidation of carbon - see fossil fuels).[4]
The last deep coal mine in the UK closed on 18 December 2015. Twenty-six open cast mines still remain open [5] and Banks Mining said in 2018 they planned to start mining a new site in County Durham.[6]

Extent and geology[edit]
The United Kingdom's onshore coal resources occur in rocks of the Carboniferous age, some of which extend under the North Sea.[7] The carbon content of the bituminous coal present in most of the coalfields is 86% to 88%.[8] Britain's coalfields are associated with Northumberland and Durham, North and South Wales, Yorkshire, the Scottish Central Belt, Lancashire, Cumbria, the East and West Midlands and Kent.
