cambrian collieryとは 意味・読み方・使い方

The Cambrian Colliery was a large coal mine that operated between 1872 and 1967 near Clydach Vale in the Rhondda Valley, south Wales. It is notable for its huge production and for two infamous explosion disasters, in 1905 and 1965, in which a total of 64 miners were killed. Its owners sank the first pits into a rich coal seam in the 1870s from which, within 20 years, over 700 tons were being extracted daily. The complex was connected to the Taff Vale Railway and had room in its sidings for over 840 wagons. The colliery's workforce, which numbered over 4,000 in 1913, was prominently involved in the Tonypandy Riot of 1910.
