South Wales is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia.
The history of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today, but has begun to decline due to the strong contribution coal plays in global warming and environmental issues, which result in decreasing demand and in some geographies, peak coal.
The South Wales Valleys are a group of industrialised peri-urban valleys in South Wales. Most of the valleys run north–south, roughly parallel to each other. Commonly referred to as "The Valleys", they stretch from Carmarthenshire in the west to Monmouthshire in the east; to the edge of the pastoral country of the Vale of Glamorgan and the coastal plain near the cities of Swansea, Cardiff, and Newport.
The South Wales Coalfield extends across Pembrokeshire, Carmarthenshire, Swansea, Neath Port Talbot, Bridgend, Rhondda Cynon Taf, Merthyr Tydfil, Caerphilly, Blaenau Gwent and Torfaen. It is rich in coal deposits, especially in the South Wales Valleys.
The Somerset Coalfield in northern Somerset, England is an area where coal was mined from the 15th century until 1973. It is part of a larger coalfield which stretched into southern Gloucestershire. The Somerset coalfield stretched from Cromhall in the north to the Mendip Hills in the south, and from Bath in the east to Nailsea in the west, a total area of about 240 square miles (622 km2). Most of the pits on the coalfield were concentrated in the Cam Brook, Wellow Brook and Nettlebridge Valleys and around Radstock and Farrington Gurney. The pits were grouped geographically, with clusters of pits close together working the same coal seams often under the same ownership. Many pits shared the trackways and tramways which connected them to the Somerset Coal Canal or railways for distribution.
The geology of Wales is complex and varied; its study has been of considerable historical significance in the development of geology as a science. All geological periods from the Cryogenian to the Jurassic are represented at outcrop, whilst younger sedimentary rocks occur beneath the seas immediately off the Welsh coast. The effects of two mountain-building episodes have left their mark in the faulting and folding of much of the Palaeozoic rock sequence. Superficial deposits and landforms created during the present Quaternary period by water and ice are also plentiful and contribute to a remarkably diverse landscape of mountains, hills and coastal plains.
Mining in Wales provided a significant source of income to the economy of Wales throughout the nineteenth century and early twentieth century. It was key to the Industrial Revolution in Wales.
Cefn Coed Colliery Museum is a former coal mine, now operating as a museum. It is located at Crynant near Neath in the South Wales Valleys.
The South Yorkshire Coalfield is so named from its position within Yorkshire. It covers most of South Yorkshire, West Yorkshire and a small part of North Yorkshire. The exposed coalfield outcrops in the Pennine foothills and dips under Permian rocks in the east. Its most famous coal seam is the Barnsley Bed. Coal has been mined from shallow seams and outcrops since medieval times and possibly earlier.
The North Staffordshire Coalfield was a coalfield in Staffordshire, England, with an area of nearly 100 square miles (260 km2), virtually all of it within the city of Stoke on Trent and the borough of Newcastle-under-Lyme, apart from three smaller coalfields, Shaffalong and Goldsitch Moss Coalfields near Leek and the Cheadle Coalfield. Coal mining in North Staffordshire began early in the 13th century, but the industry grew during the Industrial Revolution when coal mined in North Staffordshire was used in the local Potteries ceramics and iron industry.
The Cheadle Coalfield is a coalfield in the United Kingdom. Centred on the town of Cheadle, Staffordshire and its outlying villages it lies to the east of Stoke-on-Trent and the much larger North Staffordshire Coalfield. The area has been mined for many years, with documentary evidence from Croxden Abbey citing coal mining in the 13th century.
Nantgarw Colliery was a coal mine and later developed Coking coal works, located in the village on Nantgarw, Mid Glamorgan, Wales located just north of Cardiff.
Coal mining in the United Kingdom dates back to Roman times and occurred in many different parts of the country. Britain's coalfields are associated with Northumberland and Durham, North and South Wales, Yorkshire, the Scottish Central Belt, Lancashire, Cumbria, the East and West Midlands and Kent. After 1972, coal mining quickly collapsed and had practically disappeared by the 21st century. The consumption of coal – mostly for electricity – fell from 157 million tonnes in 1970 to 18 million tonnes in 2016, of which 77% was imported from Colombia, Russia, and the United States. Employment in coal mines fell from a peak of 1,191,000 in 1920 to 695,000 in 1956, 247,000 in 1976, 44,000 in 1993, and to 2,000 in 2015.
The Pembrokeshire Coalfield in West Wales is one of the smallest British coalfields, but continuously worked from the 14th to 20th centuries. The main coalfield extends across south Pembrokeshire from Saundersfoot on Carmarthen Bay westwards to Broad Haven on St Brides Bay. A small detached portion of the field is centred on Newgale on St Brides Bay.
The Lancashire Coalfield in North West England was an important British coalfield. Its coal seams were formed from the vegetation of tropical swampy forests in the Carboniferous period over 300 million years ago.
The Ingleton Coalfield is in North Yorkshire, close to its border with Lancashire in north-west England. Isolated from other coal-producing areas, it is one of the smallest coalfields in Great Britain.
The Denbighshire Coalfield in the historic county of Denbighshire in north-east Wales is one of the smaller British coalfields. It extends from near Caergwrle in the north, southwards through Wrexham, Ruabon and Rhosllannerchrugog to Chirk in the south. A small part extends into Shropshire around Oswestry. Beyond Caergwrle the coal-bearing strata continue northwards as the Flintshire Coalfield. Together the two coalfields are known as the North Wales Coalfield.
The North Wales Coalfield comprises the Flintshire Coalfield in the north and the Denbighshire Coalfield in the south. It extends from Point of Ayr in the north, through the Wrexham area to Oswestry in Shropshire in the south. A much smaller area on Anglesey where coal was formerly mined is not usually considered to form a part of the coalfield, although it is geographically in the North Wales region.
The natural resources of Wales have contributed substantially to the economic wealth of the United Kingdom from pre-Roman times to the present. Wales has a complex and varied geology with a wealth of natural minerals. Although Wales has been strongly associated with the coal industry, it has also been the world's leading supplier of slate and of copper at different times. The country lies along the western side of Great Britain and is buffeted by the prevailing South-Westerly trade winds which bring year round rain and wind but also maintain an equable temperate climate. The combination of climate and physical geography and geology have given rise to many different types of landscape and biomes rich in species variety.
The industrial revolution in Wales was the adoption and developments of new technologies in Wales in the 18th and 19th centuries, resulting in increases in the scale of industry in Wales, as part of the wider Industrial Revolution.
