Betteshanger Colliery

Overview

The biggest of Kent's four coalfield collieries, whose militant workforce made it the only Kent pit to strike during the Second World War, and the last colliery standing when Kent coal mining ended in 1989.

History

Kent's coal industry began almost by accident, discovered in 1890 when disused borings from the abandoned first Channel Tunnel project were used to investigate the local geology. The specific coal that became Betteshanger, near Deal, was found in the Lydden valley on 12 December 1912, and Pearson & Dorman Long Ltd developed the site as the last of Kent's four viable collieries, cutting the first shaft on 19 May 1924. Its 24-foot-diameter shafts, the largest of any Kent pit, took three years rather than the usual one to sink owing to serious flooding, managed using the cementation process to seal the shaft walls; first coal was raised in 1927.

The colliery drew around 1,500 miners and their families to the Deal area, many settling three miles away at Mill Hill after an initially hostile reception from Deal itself, where lodging houses and shops put up signs reading 'no miners'. Pithead baths, opening in April 1934, later let the workforce return home clean. Betteshanger drew in many of the hard-line union men blacklisted from their home coalfields after the 1926 General Strike, giving its workforce a reputation as the most militant in Kent; a 1938 strike over the treatment of pit boys was an early sign of this, and the colliery went on to employ 2,033 workers by 1945, at its peak producing up to a million tons of coal a year.

That reputation was cemented in January 1942, when around 1,600-2,000 miners struck over a new, unusually narrow coalface where management had set a production quota the men said was unachievable; the strike defied wartime Order 1305, which made strikes illegal without Ministry of Labour approval, and became the only coal strike of the Second World War. Three union branch leaders, including local Justice of the Peace Tudor Davies, were imprisoned and over a thousand miners fined, but a fortnight of hostile press coverage and government pressure gave way to negotiations at Maidstone Prison that produced an almost complete concession to the miners' original demands; the imprisoned men received royal pardons on 2 February 1942, and the government eventually remitted all the fines in July 1943. A 1968 Royal Commission later cited the episode as evidence that banning strikes by law was counterproductive.

A miner named Cephas was killed in 1934 when a loosened lump of rock fell and crushed him while he was hewing coal, one of a number of individual fatal accidents recorded over the colliery's working life. Betteshanger workers occupied the pit during the 1984-85 miners' strike and were the last in Kent, and among the last in Britain, to return to work; those who had taken part in the occupation were later dismissed and never reinstated. The colliery finally closed on 26 August 1989, ending nearly a century of coal mining in Kent.

Geology

Betteshanger worked seams of the Kent Coalfield, discovered in 1890 when disused borings from the abandoned first Channel Tunnel project were used to investigate the local geology; the specific seam that became Betteshanger itself was found in the Lydden valley near Deal on 12 December 1912.

Workings

Coal was raised via twin 24-foot-diameter shafts, the largest of any Kent colliery, the first cut on 19 May 1924; sinking took three years rather than the usual one owing to serious flooding, managed using the cementation process to seal the shaft walls.

Closure

Betteshanger closed on 26 August 1989, the last of Kent's coal mines to close and the end of coal mining in the county.

What remains

The former colliery's spoil tip has been transformed into Betteshanger Country Park (also known as Fowlmead), 250 acres of restored parkland opened in 2007 by the naturalist David Bellamy, its reshaped shale surface mixed with recycled green waste and some 130,000 shrubs and trees planted; it now draws around 100,000 visitors a year. A dedicated Kent Mining Museum opened within the park on 2 April 2022. Under more recent private ownership, planning permission for a large hotel and surf lagoon on part of the site was granted in 2024 but has faced legal challenge and remains on hold.

Little of the working colliery survives above ground; the site is now a country park.
