Collieries Betteshanger Standing to the northwest of Deal, this colliery was served by a branch off the Minster to Dover line. The colliery opened in 1924, the first coal was raised in 1927. In 1945, the workforce was 2,033, with 1,594 being employed sub-surface and 439 above. Betteshanger was infamously the location of the 1942 Betteshanger miners' strike, the only such action during World War II, which raised much public contempt despite justification. Betteshanger was the last pit to return to work after the 1984–85 Miners' Strike and it closed on 26 August 1989. A few of the buildings survive today. Shafts sunk No. 1. No. 2. Chislet Work began at Chislet in 1914, and the colliery produced its first coal in 1918. The fact that its owners, the Anglo-Westphalian Kent Coalfield Ltd., had German connections caused questions to be asked in Parliament. The company changed its name to the North Kent Coalfield Ltd., and later to Chislet Colliery Ltd. The colliery was served by the Ashford to Minster railway, and a halt was built to serve the miners. In 1945, the workforce was 1,350, with 1,023 being employed sub-surface and 327 above. In 1963-4 a 550V.dc railway was built into the south eastern area of the mine. It had formerly used battery locomotives. The colliery closed on 25 July
