Open-pit coal mining in the United Kingdom

Open-pit coal mining in the United Kingdom is in decline. Output has fallen every year since 2010. In 2010, the United Kingdom was forecast to produce about ten million tonnes (9,800,000 long tons; 11,000,000 short tons) of coal a year from open-pit mines. Most came from Scotland, with the largest operator there being the Scottish Coal subsidiary of Scottish Resources Group. Actual production in 2010 was over 13 million tonnes but this has declined to less than 8 million tonnes in 2014.

Statistics on open-pit coal mining are compiled by the British Geological Survey from information provided by local planning authorities. Open-pit coal mines usually last four or five years at extraction rates of up to a quarter-million tons a year.

Hargreaves plc still operates some sites in Scotland and is committed to maintaining its Scottish operations until May 2016. The sites include:

Banks Mining applied in October 2015 for planning permission to extract about three million tonnes of coal and other minerals from the Highthorn site in Northumberland.

The following information relates mainly to 2010 and earlier.

Miller Argent run the Ffos-y-fran Land Reclamation Scheme in eastern Merthyr Tydfil, which involves mining the coal from under 367 hectares of land made derelict by earlier coal-mining operations; the coal will be provided to the Aberthaw Power Station on the Glamorgan coast. The project started in 2007 and is expected to last 17.5 years.

The deep mine at Tower Colliery closed in 2008, but there is a plan to build an 80-hectare 165-metre open-pit mine to extract a remaining 6Mton reserve of anthracite, for which a planning application was registered in July 2010.

Energybuild Ltd operates an opencast site here; it was estimated to have 450 kton of recoverable coal in 2006, which has mostly been excavated between 2006 and 2009. The overburden was sold as road stone.

The site was approved in 1995 but operation was delayed until 1997. Celtic Energy operate a mine at Selar in the Neath Valley. Planning permission was granted to extend the extraction by 800,000 tonnes in 2013 which will keep the mine operational until 2020.

Miller Argent planned to extract 6m tonnes of coal at Nant Llesg, near Rhymney. Their application was rejected by Caerphilly county borough council on 7 August 2015. The company is considering an appeal.
