Overview

Twin collieries in the Ebbw valley near Abercarn — Celynen South, sunk from 1874, and Celynen North, sunk from 1913 — worked by the same company, eventually linked underground with the neighbouring Oakdale Colliery, and closed within months of each other at the end of 1985. Celynen South's long, accident-prone history earned it the grim nickname 'the Blood-Tub.'

History

Celynen South was sunk from 1874 by the Newport Abercarn Black Vein Steam Coal Company, with the first coal raised on 16 August 1876 from three shafts reaching between 357 and 410 yards. By 1900 the colliery employed 1,700 men and 200 horses, producing around 10,000 tons of coal a week. Its long history of fatal accidents earned it the grim local nickname 'the Blood-Tub.' The same company began sinking Celynen North in 1913, on mineral rights leased from the Llanover Estate, raising its first coal in 1916. During sinking, on 9 May 1914, pump operator William Tedstone, aged 32, suffocated 75 yards underground when a steam joint blew into his lodge room under 160 lb of pressure. Both collieries passed to Partridge, Jones and John Paton and Co. in the 1930s and were nationalised together under the National Coal Board in 1947. In 1982 Celynen North was linked underground with the nearby Oakdale Colliery complex (see MineArchive's own record). Celynen South, by then supplying high-quality coking coal to the Llanwern steelworks, closed in 1985; Celynen North's workforce was transferred to Oakdale that December as it too closed, ending Newport Abercarn's original sinking company's presence in the valley after well over a century.

Geology

South Wales Coal Measures worked through the Nine-Feet (Black Vein) and Five-Feet/Gellideg seams, the two collieries' shafts ranging from around 357 yards (Celynen South No. 1) to over 500 yards (Celynen North).

Workings

Two separate multi-shaft collieries — Celynen South (three shafts) and Celynen North (two shafts, downcast and upcast) — worked by the same company from adjoining ground, later connected underground with the neighbouring Oakdale Colliery in 1982.

Closure

Celynen South closed in 1985 after continuous working since the 1870s; Celynen North closed in December 1985, its workforce transferring to the linked Oakdale Colliery.

Abandoned workings can be dangerous — unstable ground, uncapped shafts, flooding and bad air are common even where a site looks safe from the surface. This entry describes history and general location only; it is not an access guide.
