Aberaman Colliery

Overview

A steam-coal colliery in the Aberdare valley, opened in the 1840s as part of Crawshay Bailey's Aberaman estate and sold with the whole estate to the Powell Duffryn Steam Coal Company in 1867 for £123,500. Under the National Coal Board it became more than a pit: a training centre, a road transport depot, a property repair depot and the site of a central workshop and central stores. It closed on 23 November 1962 with its reserves exhausted, the men going to Deep Duffryn, Abercynon and Fforchaman.

History

The Aberaman estate south of Aberdare was bought by the ironmaster Crawshay Bailey from the executors of Anthony Bacon II by indenture of 17 February 1837. It was several years before he began speculating for coal; by 1845, in partnership with Josiah John Guest, he had built the Aberdare Railway, and around the same time the Aberaman Ironworks and a number of collieries with it were opened. Aberaman Colliery itself is dated to 1843. Bailey's colliery activities were profitable but the depression in the iron trade meant the enterprise as a whole disappointed him, and he decided to sell up and return to Monmouthshire. By indenture of 2 February 1867 he disposed of the entire Aberaman estate — collieries, ironworks, brickworks and private railway — to the Powell Duffryn Steam Coal Company for £123,500, and retired to Abergavenny. Powell Duffryn had been registered on 28 July 1864 to buy out the Powell interests, and was in the middle of nine years of litigation over the exact underground extent and value of the collieries it had bought; it did not enter full possession until November 1873. Bailey closed the Aberaman ironworks in 1875, they having run at a loss for some time. Powell Duffryn held the colliery until nationalisation, and under the National Coal Board Aberaman took on functions well beyond winding coal: it served as a training centre, a road transport depot and a property repair depot, and housed a central workshop and central stores for the area. It was closed by the Board on 23 November 1962 because its coal reserves were exhausted, and the men were transferred to Deep Duffryn, Abercynon and Fforchaman.

Geology

The Aberdare valley worked the steam coals of the South Wales coalfield, the seams that made the district's name with the Admiralty and the world's navies. The valuable steam-coal seams on the neighbouring Blaengwawr estate began to be exploited around 1843, the same date given for Aberaman, which is the point at which the valley turned from iron to coal as its principal business.

Workings

A steam-coal colliery originally worked as part of an integrated estate: Crawshay Bailey's Aberaman holding combined the collieries with an ironworks, a brickworks and a private railway, and the Aberdare Railway he built with Josiah John Guest by 1845 was what let the coal reach a market. Under the National Coal Board the surface became a service centre for the wider area rather than simply a pit head.

Closure

Aberaman was closed by the National Coal Board on 23 November 1962 because its coal reserves were exhausted. Its men were transferred to Deep Duffryn, Abercynon and Fforchaman rather than paid off, which was the Board's usual practice where neighbouring pits still had life in them.

What remains

The colliery is gone. Aberaman is now a village whose working population largely travels to Cardiff and the M4 corridor or to Aberdare and Pontypridd; most of the industry that created it has disappeared.
