The Cwmllynfell and Ystradowen Coal Mining Heritage Trust exists to preserve and promote the interest in the coal mining history, of Cwmllynfell and surrounding areas.

Cwmllynfell Colliery [1820-1959].


1820. Cwmllynfell Colliery [was known locally as the Clink] it had a long mining history which can be traced back through the centuries to the first official mention of mining in this area the Colliery was an anthracite drift mine and commenced operations in that year.

1825. Unfortunately, five years later fifty-nine men were killed in an explosion at the mine. [There is no recorded information that can substantiate this as being a true fact].

1849/53, to illustrate local wage levels, at Cwmllynfell colliery a collier earned between 17 shillings and £2.4.3d per fortnight, an overman £1..8...0 per week, a labourer 1/10d a day and a boy with horse 1/0d a day.

The amount of coal was ascertained by placing a weighing machine near the pit mouth. Checkweighers, paid for by the miners, checked the weights, but they were not allowed to interfere with the working of the mine.

‘The Cambrian dated 9th April 1909.


The notices received by the workmen of the Cwmllynfell collieries expired on Saturday, and the tools were brought out. The friction has been very great lately and culminated in legal proceedings. 

The men were informed that operations would not be resumed unless the men agreed to abandon the crop workings, to abolish the stint, or the restriction the men have on the number of trains being filled per man per day; also, that Mabon's Day as a holiday be abolished, and that the width of the stalls is to be increased up to 8 yards wide, and also only huge coal to be filled out. 

The two sides met on Monday to discuss the matter in dispute. "

James and Aubrey worked the colliery for a long period.

1909. Rees, Thomas, 12 Nov 1909, aged 45, Assistant pitman, in a shaft; while engaged in releasing pulley-block ropes which had been used in lowering a steam pump from the surface to shaft bottom, the deceased was in a bowk disentangling a rope from the water column, when the rope due to its weight was drawn over the pulley at the top and fell down the shaft.

1914. Harris, William, 23 Jul 1914, aged 34, Hitcher, He appears to have been carried up 5 or 6 yards by the ascending cage and crushed between it and the woodwork. It is thought the automatic catch, for holding trams in cage, failed to act, and in trying to right it before the cage went away, and after he had given the signal, he was carried up.

1917. The colliery was managed by the Colliery Investment Trust Limited.

1918. The colliery employed a total of 155.

1921. Coal mining was a harsh, dangerous occupation. Poverty and hardship were rife. Mine workers were strongly unionised. They had already gone on strike against wage reduction April 1921 but failed in their demands and were forced back to work on lower pay.

1923. Cwmllynfell pit sunk.

1923. The colliery had a workforce of 285, producing anthracite coal from the big vein. 

1925. 30 June 1925, the mine owners demanded a further wage cut and an extra hour on the working day as coal was being produced at a loss.

1925. The colliery closed the ‘Big Vein’.

In 1926 they reached the Lower Seam having only worked the Big Seam.

There was a stoppage here in 1934

In 1932 Penry Davies was the previous manager, and Dan Bowen had replaced him - later on it was Dick Davies (20Mem)

In 1926 they reached the Lower Seam having only worked the Big Seam.

1926. General Strike.

On the 3 May 1926, the Trades Union Congress (TUC) called a general strike across Britain to start at one minute before midnight - the purpose of the General Strike was to obtain justice for the miners, miners had been locked out for refusing to accept wages of £1 11s 7½d.

The response of union members was fantastic: all ceased work when called upon, and practically none returned to work until the strike was over.

Coal miners had been locked out and after a long-running dispute with the government and with the mines’ private owners, who wanted them to work longer shifts for reduced pay. The miners' lock-out dragged on through the months of 1926 and was really petering-out when the decision came to end it.

St. Mary’s church hall, Ystradowen occupies the site of an old hut which was used as a soup kitchen for local miners and their families during the 1926 General Strike.

The bitter General Strike lasted 9 days and ended in betrayal and defeat of the miners. It divided Britain, brought the country to a standstill, and saw sporadic disturbances, vandalism and 9,000 arrests.

In October 1926 hardship forced men to begin to drift back to the mines. 

By the end of November most miners had reported back to work. Hardship forced men to begin to drift back to the mines.

 Many miners found they had no jobs to return to as many coal-owners used the eight-hour day to reduce their labour force while maintaining productions levels. Victimisation was practised widely.

Militants were often purged from payrolls. Blacklists were drawn up and circulated among employers; many energetic trade unionists never worked in a pit again after 1926. 

Following months of existence on poor lockout payments and charity, many miners' families were sucked by unemployment, short-term working, debts, and low wages into abject poverty.

Cwmllynfell Colliery had a poor industrial relations history (hearsay) but reopened 14.1.1929 after being idle fourteen months the men agreed to return to work on reduced pay due to the colliery being idle for 13 months.

By 1932 it was in the hands of Henderson's Welsh Anthracite Collieries Limited which was by that time a subsidiary of the Amalgamated Anthracite Collieries&nbsp Limited. Penry Davies was the previous manager, and Dan Bowen had replaced him - later on it was Dick Davies.  

1934. The Colliery closed in March 1934 and there is a reference "During the 1934 stoppage at Cwmllynfell Colliery....miners went up to the Black Mountain Colliery, it had closed some years before, but we entered the drift .... used a donkey to carry the coal down as far as Llwynrhitie where it was put on a cart pulled by a horse".  

1934. Work resumed on 21. Nov. 1934 after a lapse of eight months.

1935. The colliery employed 45 men on the surface & 170 men working underground on the middle & lower vein.

1951. On the 07th of June 1951 a fire in the middle vein stopped the colliery working and nearly closing it. The water pumps were turned off, which resulted in water reaching up to an inch from the ceiling in the coalface.

Eighty-Two [82] fully equipped rescue men sealed the district off until the fire had subsided.

It was established that the fire had extended 86 yards from the coalface and down the supply road, the fire was due to ‘Shot firing’.

1951. The colliery restarted work on the 12th of June 1951 and 350 men were. producing 250 tonnes of coal a day.

1955. saw the colliery employ 363 men, of which 165 worked on the coal face. These figures dropped to 313/142 respectively, by the following year and stabilised to 145 men at the coal faces the year before it closed.

1955. Colliery Yearbook shows the Managers Post as vacant. Manpower of 315 underground and 67 on the surface producing just 46,874 tonnes Saleable.

The number of men who lost their jobs were 253 men underground and 41 men on the surface.
