Bedwellty Pits

Overview

A colliery south of Tredegar, one of the pits of the Tredegar ironmasters' coal operations, which appears three times on the roll of Welsh mining disasters. An explosion in June 1865 killed twenty-seven, six of them boys under sixteen, and was reported with engravings in the Illustrated London News; a further explosion in March 1880 killed six more.

History

Bedwellty Pits lie south of Tredegar, in the Sirhowy valley where the Tredegar Iron Company — founded in 1800 by Samuel Homfray with Richard Fothergill and Matthew Monkhouse on a lease from the Tredegar Estate — developed the coal that fed its furnaces. The company ceased making iron in 1891 but went on developing coal mines and working pits until nationalisation. On 16 June 1865 an explosion killed twenty-seven men and boys (see Disasters, below). It was reported nationally: the Illustrated London News of 1 July 1865 carried two engravings, one of the colliery as the scene of the explosion and one of the funeral of the colliers killed. A second explosion on 10 March 1880 killed six more — Thomas Ball, 34; John Williams, 27; Thomas John Roberts, 27; Robert Cooper, 23; Charles Pugh, 19; and Henry Anthony, 29. A winding wheel survives at Bedwellty Pits as a memorial to the colliery.

Geology

The colliery worked the Coal Measures of the Sirhowy valley, on the eastern side of the South Wales Coalfield — the coal that the Tredegar ironworks were built on and that the Tredegar Iron and Coal Company went on working long after it had stopped making iron. No seam is named for this colliery in the sources read.

Workings

The colliery is recorded in the Welsh disaster rolls under the name Bedwellty Pits; no account of its shafts, seams or working arrangements has been found in the sources read.

Closure

No closure date has been found for the colliery.

What remains

A winding wheel stands at Bedwellty Pits as a memorial. The settlement of Bedwellty Pits and its railway houses survive south of Tredegar.
