Originally sunk in 1870 by Thomas and Griffiths to reach the higher bituminous coal levels, further shafts were sunk to the steam coal levels in 1878. The mine was subsequently owned by Cory Brothers and Co, who held it until Nationalisation in 1947.

By 1908 the workforce numbered 777 (steam coal pit) and 128 (house coal pit). The latter pit closed by 1945 and the steam coal pit in 1962. Large but very heavily overgrown tips still remain.
