Tynewydd Colliery was opened by J. Brogden and Sons late in 1865 to work the No. 3 Rhondda seam, a bituminous coking and house coal seam; domestic coke was manufactured in nearby coke ovens. For a short period, the fireclay and shale produced during the working of the coal seam were processed and burnt for brick making in nearby beehive type brick kilns.
The colliery was worked with naked lights and, originally, with furnace ventilation which was replaced by a steam driven fan in its later years.
During its lifetime the colliery was owned by:
T. Thomas, John Brogden and Sons (The Llynvi and Tondu Iron and Coal Co. Ltd.)
The Llynvi, Tondu and Ogmore Coal & Iron Company Ltd.
and North’s Navigation Collieries (1889) Ltd.
Tynewydd Colliery was abandoned on the 10th January 1905.
