The Coalbrookdale Coalfield is a coalfield in Shropshire in the English Midlands. It extends from Broseley in the south, northwards to the Boundary Fault which runs northeastwards from the vicinity of The Wrekin past Lilleshall. The former coalfield has been built on by the new town of Telford.
Coal-mining in the area is believed to have been undertaken by the Romans, as the coalfield lay on Watling Street. [1] Mining activity was first documented in the 13th and 14th centuries, when the monks at Buildwas Abbey were granted the right to coal and ironstone by Phillip de Benthall. [2] Although the coalfield only covers an area of 20 square metres (220 sq ft), [3] it has been noted as being historically significant on account of its location with the ironstone seams, that allowed Abraham Darby I, in 1708 to make iron more efficiently using coke, rather than charcoal, thereby starting the Industrial Revolution. [4] The River Severn also allowed for delivery of goods made in his works in Coalbrookdale. [5]
During the late 16th and early 17th centuries, the Coalbrookdale Coalfield was second only to the North East Coalfield in terms of volume and it was producing 95% of the coal in the Shropshire area. [6]
By 1896, the Coalbrookdale Coalfield had over 80 mines operating in the district; whilst most of these worked coal, some also worked the bands of fireclay too. [7] Some of the fireclay was of such quality that it was used for the manufacture of pottery and clay tobacco pipes. [8] Not all of the mines were very deep, some were described as surface mines, but the deep-mining industry in the coalfield peaked in the mid-19th century, [9] with the last coal mine, Granville, being closed in 1979. [10] Surface mining (opencasting), has been more prevalent in the western edge of the coalfield around Lawley, Little Wenlock and north of the River Severn at Ironbridge. [11]
Coal-bearing strata are to be found across three synclines; the Donnington, Madeley and Coalport synclines whilst the majority of the coalfield is subject to intense faulting. [12]
The following coal seams are recognised: [13] [13]
The coalfield extends from Broseley in the south west of the region to Lilleshall in the north east and is described as being roughly in a triangular shape. [14] Whilst it is thought that the coalfield extends towards, and into, the Staffordshire Coalfield, no mining for coal was undertaken east of the village of Shifnal. [15]
With most of the coal mines worked out by the 1960s, the idea of a new town was born, and although it was originally called Dawley New Town, Telford sprang up over the old coalfield. [16] Mining continued into the 21st century, but was all of an opencasting nature. [17] The site at Granville Colliery was transformed into Granville Country Park. [18]
Ironbridge is a riverside village in the borough of Telford and Wrekin in Shropshire, England. Located on the bank of the River Severn, at the heart of the Ironbridge Gorge, it lies in the civil parish of The Gorge. Ironbridge developed beside, and takes its name from, The Iron Bridge, a 100-foot (30 m) cast iron bridge that was built in 1779.
Telford is a town in Shropshire, England. It is the administrative centre of Telford and Wrekin borough, a unitary authority which covers the town, its suburbs and surrounding settlements. The town is close to the county's eastern boundary, and near the River Severn.
The Ironbridge Gorge is a deep gorge, containing the River Severn in Shropshire, England. It was first formed by a glacial overflow from the long drained away Lake Lapworth, at the end of the last ice age. The deep exposure of the rocks cut through by the gorge exposed commercial deposits of coal, iron ore, limestone and fireclay, which enabled the rapid economic development of the area during the early Industrial Revolution.
Coalbrookdale is a village in the Ironbridge Gorge and the Telford and Wrekin borough of Shropshire, England, containing a settlement of great significance in the history of iron ore smelting. It lies within the civil parish called the Gorge.
Donnington is an area / housing estate located in the borough of Telford and Wrekin and ceremonial county of Shropshire, England. The population of Donnington Ward was 6,883 at the 2011 census.
Broseley is a market town in Shropshire, England, with a population of 4,929 at the 2011 Census and an estimate of 5,022 in 2019. The River Severn flows to its north and east. The first iron bridge in the world was built in 1779 across the Severn, linking Broseley with Coalbrookdale and Madeley. This contributed to the early industrial development in the Ironbridge Gorge, which is now part of a World Heritage Site.
Madeley is a constituent town of Telford and a civil parish in the borough of Telford and Wrekin, Shropshire, England. The parish had a population of 17,935 at the 2001 census.
Abraham Darby III was an English ironmaster and Quaker. He was the third man of that name in several generations of an English Quaker family that played a pivotal role in the Industrial Revolution.
The geology of Shropshire is very diverse with a large number of periods being represented at outcrop. The bedrock consists principally of sedimentary rocks of Palaeozoic and Mesozoic age, surrounding restricted areas of Precambrian metasedimentary and metavolcanic rocks. The county hosts in its Quaternary deposits and landforms, a significant record of recent glaciation. The exploitation of the Coal Measures and other Carboniferous age strata in the Ironbridge area made it one of the birthplaces of the Industrial Revolution. There is also a large amount of mineral wealth in the county, including lead and baryte. Quarrying is still active, with limestone for cement manufacture and concrete aggregate, sandstone, greywacke and dolerite for road aggregate, and sand and gravel for aggregate and drainage filters. Groundwater is an equally important economic resource.
The Iron Bridge is a cast iron arch bridge that crosses the River Severn in Shropshire, England. Opened in 1781, it was the first major bridge in the world to be made of cast iron. Its success inspired the widespread use of cast iron as a structural material, and today the bridge is celebrated as a symbol of the Industrial Revolution.
Seatearth is a British coal mining term that is used in the geological literature. As noted by Jackson, a seatearth is the layer of sedimentary rock underlying a coal seam. Seatearths have also been called seat earth, "seat rock", or "seat stone" in the geologic literature. Depending on its physical characteristics, a number of different names, such as underclay, fireclay, flint clay, and ganister, can be applied to a specific seatearth.
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 Shropshire Canal was a tub boat canal built to supply coal, ore and limestone to the industrial region of east Shropshire, England, that adjoined the River Severn at Coalbrookdale. It ran from a junction with the Donnington Wood Canal ascending the 316 yard long Wrockwardine Wood inclined plane to its summit level, it made a junction with the older Ketley Canal and at Southall Bank the Coalbrookdale (Horsehay) branch went to Brierly Hill above Coalbrookdale; the main line descended via the 600 yard long Windmill Incline and the 350 yard long Hay Inclined Plane to Coalport on the River Severn. The short section of the Shropshire Canal from the base of the Hay Inclined Plane to its junction with the River Severn is sometimes referred to as the Coalport Canal.
The Manchester Coalfield is part of the South Lancashire Coalfield, the coal seams of which were laid down in the Carboniferous Period. Some easily accessible seams were worked on a small scale from the Middle Ages, and extensively from the beginning of the Industrial Revolution in the early 19th century until the last quarter of the 20th century. The Coal Measures lie above a bed of Millstone Grit and are interspersed with sandstones, mudstones, shales, and fireclays. The Lower Coal Measures occupy the high ground of the West Pennine Moors above Bolton and are not worked in the Manchester Coalfield. The most productive of the coal measures are the lower two thirds of the Middle Coal Measures where coal is mined from seams between the Worsley Four Foot and Arley mines. The deepest and most productive collieries were to the south of the coalfield. The coalfield is affected by the northwest to southeast aligned Pendleton Fault along the Irwell Valley and the Rossendale Valley anticline. The Coal Measures generally dip towards the south and west. Numerous other smaller faults affect the coalfield. The Upper Coal Measures are not worked in the Manchester Coalfield.
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 Bristol Coalfield is a geologically complex coalfield in the west of England. Comprising the coal-bearing rocks arranged around the Coalpit Heath Syncline and Kingsdown Anticline, it extends beneath the eastern parts of the city of Bristol and northwards through southern Gloucestershire. The coalfield is sometimes referred to together with the Somerset Coalfield, which lies to its south, as the Bristol and Somerset Coalfield. There are also two outlying coal-mining areas, the Severn Coalfield and the Nailsea Basin which are described below.
The Fife Coalfield was one of the principal coalfields in Scotland. Over fifty collieries were in operation at various times between the middle of the nineteenth century and the closure of the last pit in 1988. The coalfield extended across the southern part of Fife where rocks of the Coal Measures Group occur and was one of a series of coalfields throughout the Midland Valley from which coal was won by both deep workings and opencasting methods. It is traditionally divided into the West Fife, Central Fife and East Fife coalfields with Kirkcaldy having been a particularly important area. Some of the mines extended beyond Fife under the Firth of Forth following the seams which occupy the Leven Syncline which extends to the south shore of the firth at Musselburgh and beyond.
The coal industry in Wales played an important role in the Industrial Revolution in Wales. Coal mining in Wales expanded in the 18th century to provide fuel for the blast furnaces of the iron and copper industries that were expanding in southern Wales. The industry had reached large proportions by the end of that century, and then further expanded to supply steam-coal for the steam vessels that were beginning to trade around the world. The Cardiff Coal Exchange set the world price for steam-coal and Cardiff became a major coal-exporting port. The South Wales Coalfield was at its peak in 1913 and was one of the largest coalfields in the world. It remained the largest coalfield in Britain until 1925. The supply of coal dwindled, and pits closed in spite of a UK-wide strike against closures. Aberpergwm Colliery is the last deep mine in Wales.
Hapton Valley Colliery was a coal mine on the edge of Hapton near Burnley in Lancashire, England. Its first shafts were sunk in the early 1850s and it had a life of almost 130 years, surviving to be the last deep mine operating on the Burnley Coalfield.
The Cinderloo Uprising took place at Old Park in the Coalbrookdale Coalfield on 2 February 1821, when the South Shropshire Yeomanry confronted a crowd of 3,000 mostly striking workers who had gathered to protest the continued lowering of their pay.
