National Coal Board, Records

Scope and Content

Records of the National Coal Board (NCB) and the British Coal Corporation, South Wales Area. Records are arranged by the creating department, with records concerning a variety of subjects found across the different series, such as colliery planning and development schemes, capital expenditure, colliery closures, strikes and industrial relations (particularly material on the 1984/1985 Miners’ Strike), industrial disease, accidents, compensation, NCB property, public relations (including colliery profile leaflets and press statements), accounts, welfare (including plans of pithead baths), the Aberfan disaster and Tribunal, tip control (including a set of tip plans) and opencast operations. Within the Mining Department papers there are plans showing underground workings across the south Wales coalfield and at individual collieries. Other plans within the collection include those relating to machinery and engineering.

There is a substantial photographic print and negative collection which includes images of collieries across the south Wales coalfield. The collection includes (but is not limited to) images of individual collieries (above and below ground), disasters, strikes, royal visits, groups of workmen, general studies of ‘valley life’, colliery horses, coal face work, pithead baths, medical centres, people, machinery, buildings, ancillary works, scientific equipment, exhibitions and staff training.

Records created at individual collieries also feature within the collection and include accident and compensation registers, pay books, rent books and a horse purchase book. Some of this material was in use by pre-vesting colliery companies and continued by the NCB.

Alongside records created by the NCB, the collection includes pre-vesting date records kept by the NCB. This material comprises records relating to coal mining and associated industries before nationalisation. This series includes (but is not limited to) papers of The Monmouthshire and South Wales Coal Owners' Association (including a set of press digests covering the period immediately before the nationalisation of the coal industry), a set of newspaper cutting volumes and terms of settlement papers.

The NCB also deposited the pre-nationalisation records of individual colliery companies. See the related collections field for a list of these collections.

Administrative / Biographical History

In 1945 the newly-elected Labour government announced its intention to nationalise the British coal industry. The Coal Industry Nationalisation Act was passed on 12 July 1946 and it provided for the establishment of a National Coal Board (NCB) in which all the assets of the coal industry would be vested. The NCB would be responsible for running the whole industry, split into the following eight Divisions: No.1 Scottish; No.2 Northern; No.3 North-Eastern; No.4 North-Western; No.5 East Midland; No.6 West Midland; No.7. South-Western; No.8 South-Eastern.

On the vesting date, 1 January 1947, the NCB’s South Western Division consisted of 220 collieries and over 100 small privately owned mines. The Division was sub-divided into the following areas; No.1 Swansea, No.2 Maesteg, No.3 Rhondda, No.4 Aberdare, No.5 Rhymney, No.6 Monmouthshire and Severn (Forest of Dean, Somerset, Bristol).

In the early 1940s there had been a great demand for coal and many pits had been kept open although operating at a loss. This great demand continued after nationalisation, but the NCB embarked on a policy of distributing the available finances to the collieries that they believed would have the best returns. In the period 1947 to 1959 this led to the closure of 76 collieries. However, alongside the closures, the NCB also started to invest heavily in new ventures, redeveloping collieries such as Mardy and Fernhill in the Rhondda and Llanharan and Nantgarw near the southern outcrop.

The closure policy had the desired effect of improving the output per manshift at collieries, but ultimately it failed in its attempts to stem the huge losses that the Division was running up. The mergers of pits continued in the 1960s; Wyndham and Western Collieries were merged in 1965, and Tower and Fernhill Collieries in 1966, with Merthyr Vale and Deep Navigation collieries receiving major investments.

The 1960s also saw the occurrence of one of the worst disasters in the history of the British coal industry. On 21 October 1966, 144 people, 116 of them children, were killed when a tip of coal waste slid onto the welsh village of Aberfan. On 26 October 1966, the Secretary of State for Wales, appointed a Tribunal to inquire into the causes of, and circumstances relating to, the Aberfan disaster. The NCB accepted the lessons and recommendations set out in the Report of the Tribunal and gave the Minister of Power an immediate account of what they were doing to remedy the shortcomings. Comprehensive information about all NCB tips was assembled (for the first time) and policies were devised for controlling them. A tip safety committee was established by the NCB, and a programme of inspection, investigation and remedial work was installed.

In order to make the south Wales coalfield more efficient, and to meet the demand for coal, more mergers of collieries were carried out during the 1970s, including the mergers of Lady Windsor and Abercynon in 1975, Nantgarw and Windsor in 1974 and Garw and Ffaldau in 1975.

By the late 1970s, the pit closures had started contributing to an industrial depression in south Wales. With a rise in unemployment, people became increasingly concerned not only with the loss of jobs, but also the effect that unemployment would have on the mining communities as a whole. In 1984 the National Coal Board declared that it wished to close 20 pits across Britain, with the loss of 20,000 jobs. On 12 March 1984, Arthur Scargill, President of the NUM, called a national strike against the pit closures. Many miners were involved in picketing and protesting, including miners from 28 pits in the south Wales coalfield. The strike lasted for nearly a year, with the miners conceding defeat on 3 March 1985.

On 1 January 1987, the NCB became the British Coal Corporation. Over the next few years more collieries were closed and mining operations in Wales, under the British Coal Corporation, came to an end in 1994, with the closure of Tower No.4, the last British Coal Corporation deep mine in the south Wales coalfield.

With the passing of the Coal Industry Act 1994, the industry wide administrative functions of British Coal were transferred to the Coal Authority and its economic assets were privatised. The British Coal Corporation was wound up in 1997.


Where identifiable, records have been listed by the creating department within the National Coal Board. Notable exceptions are the individual collieries, photographic collection and pre-vesting material, for which an artificial arrangement has been created based on subject and type of record.

Appraisal Information

Appraisal has taken place retrospectively, with all records which meet the collection policy of the Glamorgan Archives having been retained. Duplicates destroyed.

Custodial History

DNCB comprises records deposited and presented by the National Coal Board and the British Coal Corporation in the period 1957 to 1997. Many records were deposited or presented following the British Coal Corporation's review of their records leading up to the time of privatisation, however accession data for much of the material deposited by the British Coal Corporation is limited. At that time the British Coal Corporation was faced with the disposal of some 45 miles of records which had accumulated since the nationalisation of the industry in 1947.

A number of records that were deposited by the National Coal Board and the British Coal Corporation were those of pre-vesting private colliery companies that were not integrated with NCB administration. This material has been separated from the National Coal Board (DNCB) collection and new fonds have been created for each colliery company. Where pre-vesting date records were not clearly associated with a particular colliery company, these records have been retained within the DNCB collection. See the related records field for a list of the records of pre-vesting private coal companies that have been separated from the National Coal Board collection.

The collection was previously listed under references attributed at the time of deposit, with no clear cross referencing between each individual set of records. Archival appraisal of the deposits had not been undertaken due to the scale of the collection, staffing and storage limitations. Since deposit, some work had been undertaken to re-catalogue material, including work to catalogue pre-vesting date material, however the amount of material and complexity of the records still meant that some parts of the collection were not listed in detail. A cataloguing project, funded by the Wellcome Trust in 2016-2019, enabled the collection to be fully surveyed, appraised and catalogued.


Accruals are not expected.
