locomotives load coal from the already closed Abernant Colliery, 1989 Production started two years later, with coal extracted along the
Amman Valley branch of the former
Llanelly Railway and Dock Company, and on to the mainline at
Pantyffynnon. In 1962, the colliery developed access to the Red Vein seam, resulting in the abandonment of the lower Peacock seams from 1963. The result was that during the 1970s, 900 men produced an average of 300,000 tonnes of coal per annum, from a system that covered with over of roadway. The colliery was one of the first NCB pits to deploy retreat mining, whereby roadways were driven to the limit of the coal reserves, and then the
coal faces then worked towards the pit bottom. ==Closure==
