Abertridwr, Caerphilly
Abertridwr (Welsh: the mouth of the three waters) is a village in the county borough of Caerphilly, Wales, situated three miles north-west of Caerphilly town.
Like many villages and towns in the area, Abertridwr was a coal mining community within the South Wales coalfield.
[edit] Windsor Colliery
The sinking of two shafts of the Windsor Colliery commenced in 1895 by the Windsor Colliery Co. Ltd., to a depth of around 2,018 feet. The first coal was raised in 1902,[1] with the workings connected underground to the Universal Colliery located in Senghenydd for ventilation purposes.
On 1 June 1902, a platform collapsed in the mine, tipping nine men into 25 feet of water, which had gathered in the sump. Three managed to escape drowning by clinging onto floating debris, but the other six lost their lives.[1]
The colliery was nationalised, and became part of the National Coal Board in 1946. During 1976, it became linked underground with the Nantgarw colliery, and both collieries were worked as one unit, with coal winding and processing via Nantgarw. From 1976, production was concentrated at Nantgarw, with Windsor kept open for ventilation, methane extraction, and an emergency way out.[2]
The whole Nantgarw/Windsor unit closed on the 6 November 1986. Tyn y Parc (Welsh: house on the park) housing estate now occupies the site.
