Harworth Colliery

Overview

Harworth Colliery was a Bassetlaw coal mine sunk from 1913, whose Barnsley-seam coal fuelled the LNER's Flying Scotsman on its record-breaking 1932 run. It closed in 2006 after 86 years of production and was demolished a decade later for housing.

History

Work began sinking Harworth Colliery's shaft in 1913, when the Northern Union Mining Company was set up with German investment; the First World War halted construction, and in 1917 the pit was bought by Barber, Walker & Co. for £80,100. Sinking resumed in 1921, and both shafts reached the Barnsley seam, at 848 metres, on 29 October 1923, after underground faults had complicated the work. A 4.2 km railway connection to the East Coast Main Line, including a 256-foot viaduct over the River Ryton, was completed in 1924, and a further connection to the South Yorkshire Joint Railway followed in 1928 to handle a forecast 5,000 tons of coal a day. Harworth's coal was graded by depth, the upper layers suited to steaming and the lower to house and coking use, and the colliery's output supplied railway companies including the LNER -- its coal was used by the Flying Scotsman on its celebrated record-breaking run in 1932. Concrete headgears, built in the late 1950s, were themselves replaced by new headgears in 1989 (No. 1 Shaft) and 1994 (No. 2 Shaft), and the colliery reached a production capacity of one million tonnes a year by 1993, with later output supplying the Drax and Cottam power stations via the South Yorkshire Joint Railway. UK Coal warned the pit's roughly 400 workers in 2002 that it faced closure amid annual losses of £8 million, and by 2005-06, with around 450 employees, a further £50 million investment would have been needed to access a new seam offering perhaps 25 more years of reserves; the colliery closed instead. A 2008 proposal to reopen Harworth, backed by restoration work on underground roadways, ultimately came to nothing, and the colliery was demolished in April 2016 to make way for housing.

Workings

Worked the Barnsley and Parkgate seams via two shafts, connected by rail to both the East Coast Main Line (1924) and the South Yorkshire Joint Railway (1928).

What remains

The colliery was demolished in April 2016; the site has been redeveloped for retail, industrial and residential use, including the 'Simpson Park' housing development named for the cyclist Tom Simpson.

Redevelopment

Redeveloped by the Harworth Group (successor to UK Coal) as 'Simpson Park', comprising around 1,200-1,300 homes and a primary school, named after the cyclist Tom Simpson.
