Graig Merthyr Colliery was sited near Pontardulais in the Amman Valley. The first pits were sunk during 1873 and is recorded to have been worked by the Graigola Colliery Company by 1913. In 1917 the owners changed their name to the Graigola Merthyr Co. Ltd. and became members of the Monmouthshire and South Wales Coal Owners Association.
