Administrative/Biographical history: The Bargoed Colliery (Glamorgan) was sunk by the Powell Duffryn Steam Coal Company between 1887 and 1901. The first coal was produced in 1901. The colliery consisted of three shafts, the North and South (Steam Coal at 705 and 625 yards deep respectively) and the Brithdir house coal, which was sunk in 1903. This colliery broke the world record for production of coal in a single shift when 4,020 tons were produced here in 1909. Coal production ceased at the Brithdir in 1949 but it was then used for many years as a training centre. In addition to porducing coal, processing on-site took place to convert the coal to cokee, and a range of by-products were extracted, including benzole, naphthalene and tar, marketed as "Synthaprufe", "Synthacold", and "Synathaflex". The mine was nationalised in 1947, and came under the control of the National Coal Board. The old coke ovens were replaced in 1949-1950. Bargoed colliery closed in 1977.
