Overview
A Bryndu company pit at Cefn Cribbwr, near Kenfig Hill, sunk from 1900, which proved the Six Feet seam in 1908 and employed 253 men by 1910 but closed in 1913 because of bad geological conditions.
History
The Bryndu Colliery Company began sinking the Mill Pit at Cefn Cribbwr, near Kenfig Hill, in 1900. In spring 1908 the sinkers struck the Six Feet seam, 5 feet 8 inches thick in two beds with four inches of shale between, of excellent bituminous coal: the second seam proved there, under the management of D. J. Rees and Richards, on land of the Margam estate. The company planned to develop it and lay down extensive sidings.
The pit employed only 80 men in 1908, but 253 by 1910, working the Two Feet Nine, Six Feet, Esgyn, Rock, Crow Foot and Red Vein seams. After a short life it was closed in 1913 because of bad geological conditions, the year in which, by one account, Bryndu itself closed.
