DisgrifiadTwo shafts were sunk at the site between 1954 and 1956, to form a new 'super pit' and exploit an area of anthracite of over 500 square km. It was later planned to be the site of the proposed Carway Fawr Drift mine, but closed in 1989. The colliery was served by the Llanelly and Mynydd Mawr Railway (nprn 411059), which had been cut back from its original Cross Hands terminus in 1966; it closed at the same time as the colliery.
