'NC Bloody B': The National Coal Board in south Wales

Post War Britain

The dismal history of the coal industry between the world wars, government control during the Second World War and the need for coal in post-war Britain made nationalisation of the British coal industry almost inevitable after the election of a Labour government in 1945.

'Vesting Day', 1 January 1947, was largely welcomed in Welsh collieries when the south Wales coalfield became part of the South-Western Division of the National Coal Board (NCB). Assets taken over by the NCB in the UK included over 1,400 coal mines, 225,000 acres of farm land, 140,000 miners' houses, shops, offices, hotels, swimming baths, a holiday camp and a cycle track!

Investment and Disappointment

Nationalisation brought in considerable new investment for south Wales. Between 1948 and 1953, nearly £32 million was invested in the Cardiff region alone, with the reconstruction of Nantgarw Colliery cost £4.5 million. There was increased mechanisation at the coal face and drives to improve health and safety. However, by the mid-1950s, the NCB began to be seen as remote as any of the previous private coal owners. Investment had also often failed to bring results, with the expensive Nantgarw Colliery producing a disappointing 100,000 tons of coal a year.

Closures and disasters

Even from the early days of the NCB there was a tendency to close smaller, uneconomic pits and reorganise the larger ones. However, during the 1960s a deliberate rundown of the south Wales coalfield had begun. No other British coalfield suffered such closures - in 1960 there were 106,000 south Wales miners, by 1970 there were 60,000. The pace of closures only slackened off during the Middle East oil crisis of the mid-1970s.

1960, an explosion at Six Bells Colliery killed 45 miners, and on the morning of Friday, 21 October 1966, a large section of the spoil heap of Merthyr Vale Colliery slid down the hillside onto the village of Aberfan, killing 144 people including 116 children.

The 1960's

The 1960s saw the development of new 'super pits' at Abernant, Brynlliw and Cynheidre Collieries as well as the reorganisation of existing collieries such as Coegnant, Deep Navigation and Merthyr Vale.

The decade also saw all British mineworkers brought onto the same pay rate. Both management and trade unions broadly welcomed this agreement, although many men saw a substantial fall in their incomes.

The Agreement forged a greater sense of unity between UK coalfields, which paved the way for the national strikes of 1972 and 1974, which were fought over wages, the latter dispute bringing about the fall of the Conservative government.

The final years

By the early 1980s the British mining industry had become one of the safest and most efficient in Europe. However, a new Conservative government was in place and a new round of pit closures announced. The Welsh coalfields were especially vulnerable due to the age of the collieries and the difficult geology.

Although closures had been reluctantly accepted in the past, the lack of alternative employment led to calls for industrial action. The last great miners' strike began in March 1984 and lasted a year. The defeat of the miners paved the way for the final destruction of the Welsh coal industry.

The next ten years saw the end of coal as a nationalised industry. In 1994, Tower Colliery, the last remaining deep coal mine in Wales was closed by the NBC, (renamed British Coal). However, convinced that the mine was still economical, 239 miners bought the colliery with their own redundancy money and the mine remained operational until it's final closure on 25th January 2008, bringing to an end 200 years of deep coal mining in south Wales.

It would be interesting to see what coal filled the gap after the mines were closed down. Who owned the coal that came in back then, and that comes in now?

I don't know much about minng as i am 12, but had to research it for homework. Seems quite a dangerous job, and the landslide in 66 killed 116 kids. That wouldn't happen today. A kid can't even ride a bike without health and safety interfering. They should know that no kid has any awareness of health and safety today. Go us!!

It's not quite true to say that defeat of the Miner's Strike in 1984/5 "paved the way for the final destruction of the Welsh coal industry": the economics of closure were in place before the strike and would have followed strike or not. It is a shame that the interesting post-mining history isn't mentioned: the investment in reclamation works and continuing opencast industry are an important part of the story.
