Hopkinstown was the scene of one of Wales' long, sad list of mining disasters, which occurred at the Great Western Colliery on 11th April 1893 and resulted in the deaths of 63 men and boys. In the worst of all, at Senghenydd on 14th October 1913, 439 miners and one rescuer died. The company and their manager were thought to have been negligent and the inquiry found that they had committed numerous breaches of the Coal Mines Act, which had been passed in 1911 partly as a result of an earlier explosion at the same colliery which had killed 81 men. The company was fined £10 and the manager £24.
