Opened in 1926, the Taff Merthyr Colliery was one of the last collieries to be sunk in Wales by a private company – the Powell Duffryn Steam Coal Company. It was also one of the most controversial.
The two shafts of the Taff Merthyr Colliery were sunk between 1922 and 1924 to approximately 1900 feet and were 21 feet in diameter, but the development of the colliery took place during the 1926 General Strike. The pit officially opened just after the end of the strike, but the owners of the company insisted that no members of the South Wales Miners’ Federation could be employed at this new pit and they set up a company union, the South Wales Miners Industrial Union, which the miners were expected to join in order to work.
Throughout the 1920s and early 1930s the pit, together with others in the South Wales valleys became major trouble spots in the struggle for democratic representation with torchlight processions, stay down strikes and mass meetings, culminating in the strike of 1934/5. Taff Merthyr ‘strike breakers’ went into the mine under police protection and fought with the stay-down strikers resulting in 40 men being injured in the battle.
The anger felt by miners and their wives towards the ‘scab’ workforce often spilled into the streets with physical violence and other forms of intimidation. Crowds would assemble on the streets and as this labour-force passed silence was observed with doffing of caps and caps until they passed out of sight (taken from the Western Mail 1935). This resentment was to remain in the village for many years.
During the peak years of the early 1930’s however, the pit employed more than 1,600 men and produced an annual tonnage of over 600,000. With the outbreak of the Second World War, Bevin Boys were employed at the colliery, and in 1945 it was reported that 1,119 men were employed at the colliery.
The colliery was nationalised in 1947, and at that time it employed 153 men on the surface and 874 underground.
During the early seventies, 735 men were employed and they produced 340,000 tons of coal annually from the seven feet coal seam. £ 8 million was invested in the colliery in the mid-seventies and the work was completed in August 1978 and it involved deepening shafts to 640 meters and building a new coal preparation plant and MGR dispatch system.
In 1992 Taff Merthyr was amongst 31 pits scheduled for closure, despite protests and the widely held opinion that there were at least 10 years reserves of coal. Safety and maintenance work continued during a review, but it seemed inevitable that 368 coal workers would lose their livelihood when tons of rubble and other material for filling the shafts were delivered before the review was even concluded. The final shift was worked on 11 June 1993. There was talk of a miners buy out but it never materialised and the winding gear was demolished by explosion on 22 July 1994.
