Cwrt Herbert Colliery

Overview

A steam-coal colliery just east of Neath Abbey, near workings the Parsons family began in 1793, whose village of Cwrt Herbert grew up around it. Its No. 1 shaft was sunk in 1870 to the Graigola seam at 154 yards through the Victoria seam. Under the Main Colliery Company it employed around three hundred men, and five colliers died in 1906 when gas reached a gob fire. It closed in January 1929.

History

Cwrt Herbert, or Court Herbert, lay a little east of Neath Abbey near earlier workings begun by Richard Parsons in 1793, and his son John Parsons owned the colliery in 1845. The Dynevor Coal Company held it by 1869. The No. 1 shaft, the upcast, was sunk in 1870, elliptical and 19 feet by 12, to the Graigola seam at 154 yards, passing through the Victoria seam at 125; a second shaft, 14 feet in diameter, went to 150 yards, and coal from both seams was wound from the lower landing in the Graigola. By 1880 the owners were the Dynevor Duffryn Colliery Company, and by 1894 the Main Colliery Company, which also worked Duffryn Main, Brithdir and other Neath pits under the manager Richard Thomas; Cwrt Herbert employed 246 that year and 283 in 1896, raising steam and manufacturing coal. On 1 June 1906 an accumulation of gas reached a gob fire, to which the colliery was prone, and exploded, killing five colliers (see Disasters, below). Employment reached 341 in 1910 and was 315 in 1918, and in 1923 the pit worked the Graigola and Victoria seams. It closed in January 1929.

Geology

Worked the Graigola seam and the Victoria seam above it, 125 yards down, in the western South Wales Coalfield; the Victoria was 4 feet 9 inches thick in 1888, worked by pillar and stall, and prone to gob fires.

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

Workings

Two shafts: No. 1, the upcast, elliptical, 19 by 12 feet and 154 yards deep to the Graigola; a second, 14 feet in diameter and 150 yards deep. Coal from both seams was wound from the Graigola landing.

Closure

The colliery closed in January 1929; the sources read give no reason.

What remains

The village of Cwrt Herbert, which grew up to serve the colliery, remains. No report of surviving colliery remains has been found.
