Six Bells Colliery was a colliery located in Six Bells, Abertillery, Gwent, Wales. On 28 June 1960 it was the site of an underground explosion which killed 45 of the 48 miners working in that part of the mine. It is now the site of the artistically acclaimed Guardian memorial to those events, designed by Sebastian Boyesen; although the memorial primarily commemorates those who died at Six Bells, it is dedicated to all mining communities wherever they may be. Sinking The colliery was originally opened as Arael Griffin on the site of an earlier balance shaft which had been sunk in 1863 by Thomas Phillips Price at Hafod Van. In 1892 John Lancaster and Co. began sinking two shafts on the opposite side of the Ebbw Fach River. On 9 February 1895 four men lost their lives during the shaft sinking, when the bowk (large barrel) in which they were riding capsized, and they fell to the shaft bottom. Private operation: 1896-1947 By 1896 it was owned by Partridge Jones and Co., when there were 173 men employed in the sinking, including 101 on the surface. Coal winding began at Six Bells in 1898, and was transported south to Newport on the Newport and Pontypool Railway, later part of the Great Western Railway. Hafod Van slope was opened in 1909, and employed 122 men by 1910. It closed in 1914 due to a lack of manpower, when the colliery employed 2,857 men. A New Hafod Van slope was opened in 1922, and was worked until 1928. By 1923, there were 859 men employed at No.4 pit, working the Big Vein and Three Quarter seams. At No.5 there were 1,529 men employed, working the Black and Meadow Vein seams. Due to the economic downturn, Six Bells was mothballed in 1930 for several years because of lack of trade. John Paton took over the mine in 1936 until nationalisation in 1947, when there were 1,534 men employed. Nationalisation The neighbouring Vivian Colliery closed in 1958 and for some years the Vivian's shaft was used as a downcast for Six Bells. By the beginning of 1960, the colliery was producing 338,000 tonnes of coal and employed 1,291 men.
