Cwmaman Colliery

Overview

Shepherd's Pit, sunk in 1849 in the Aman valley above Aberdare and known locally by the founder's name for the rest of its life. It worked steam coal for eighty-six years, employed over a thousand men, and closed in 1935; the pub on the corner is still named after him.

History

Cwmaman was sunk in 1849 to the Gellideg seam by Thomas Shepherd in partnership with H. J. Evans, about five hundred yards west of Fforchaman, and the coal was found in December of that year. The village called it Pwll Shepherd — Shepherd's Pit — and went on calling it that. The downcast shaft went 232 yards to the Four-Feet seam and the upcast 218 yards to the Two-Feet-Nine; ventilation was by furnace at first and the winding by water balance. From 1873 Thomas Shepherd worked the colliery alone with Griffith Thomas as his manager, until the Cwmaman Coal Company was formed on 13 January 1882 to acquire the belongings of John Hall and others. In 1886 the upcast was deepened to the Gellideg and a Waddle fan thirty feet across was installed in place of the furnace. It was a big pit by the 1890s. The Inspector of Mines list for 1896 gives 1,078 men producing steam coal, and 1,012 were employed in 1908. By 1918 Cwmaman had been integrated with the Fforchwen and Trewen collieries under D. R. Llewellyn, the three employing 1,836 men between them; a list of 1923 gives 924 at Cwmaman itself, working coal and ironstone from the Nine Feet, Bute, Nos. 1 and 2 Yard, Red and Seven Feet seams. By 1930 it was held by the Bwllfa and Cwmaman Collieries Limited, a company incorporated in 1891. The pit killed children as readily as men. Thomas Howells, aged twelve, died under a fall of roof on 4 July 1885; Joseph Howells, also twelve, was crushed by trams on 19 April 1886, the day after Thomas Evans, aged sixty-one, went the same way. The colliery closed in 1935.

Geology

The colliery worked the steam coal seams of the Aberdare district in the eastern South Wales coalfield. The shafts were sunk to the Four-Feet and Two-Feet-Nine and later deepened to the Gellideg; the 1923 return names the Nine Feet, Bute, Nos. 1 and 2 Yard, Red and Seven Feet, with ironstone raised alongside the coal.

Geological setting: Sedimentary Beds and Seams (well documented example)

Workings

Two shafts sunk in 1849: a downcast 232 yards to the Four-Feet seam and an upcast 218 yards to the Two-Feet-Nine, with furnace ventilation and water-balance winding at first. In 1886 the upcast was deepened to the Gellideg and a Waddle fan thirty feet in diameter replaced the furnace.

Closure

Closed in 1935.

What remains

No account of the colliery site as it is now was found. The village stands; the Shepherds Arms on the corner of Fforchaman Road and Pwllfa Road, which dates from 1850 and is named after the colliery's founder, is still there.

No account of surviving remains was found in the sources read.
