Administrative / Biographical History
Glanamman Colliery was situated at Glanamman in the Amman Valley. The mine was being worked by 1913 but there is no record of its exact start date. Glanamman was an anthracite slant mine and was owned by Amman Valley Collieries Ltd. of London. In 1929, the Colliery was taken over and expanded by Glanamman Anthracite Collieries Ltd.
After nationalisation in 1947, Glanamman Colliery was placed in the National Coal Board's South Western Division, No. 1 (Swansea) Area. This Area produced huge losses which were noticably more than any other NCB Area. The NCB decided to re-organise the Collieries in order to make the Area more productive and profitable. This resulted in the closure of many Collieries, including Glanamman, during 1948.
