During the late 1890's the owners had become Lewis Merthyr Consolidated Collieries Limited and it had developed into a unit with four winding shafts (including Coedcae and Hafod), with a total weekly output averaging 20,000 tons. By 1908 there were 1,053 men employed at Bertie pit and 1,066 at the Trefor pit. The colliery was using the latest blast (compressed air) driven coal-cutting machinery in some seams well before the first world war and the annual output reached 1.500.000 tons per year. Closed in 1983
