MineArchiveMines in Rhondda Cynon Taf
Rhondda Cynon Taf's coal industry produced two of the South Wales Coalfield's most significant collieries: Lewis Merthyr, which grew to employ around 5,000 people, and Merthyr Vale, once the biggest colliery in the entire coalfield, whose waste tips collapsed onto the village of Aberfan in 1966 in one of Britain's worst mining disasters.
