Denbighshire 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. History The shallower parts of the Denbighshire Coalfield were worked extensively in the early nineteenth century, most of the coal being used in the iron industry. In the mid-nineteenth century, much deeper pits were established and a network of railways was built in the Wrexham area to transport the coal. A report on the North Wales Coalfield in the 1950s found that the reserves of coal were running low and that in the Denbighshire Coalfield, the geology of the coal-bearing strata dipped rapidly rendering it unlikel ...

Stratum
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Coal Mining Regions In Wales
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bettisfield Formation
Bettisfield ( cy, Llys Bedydd; ''standardised'': Bettisfield) is a village of about 150 dwellings in Wrexham County Borough, Wales and stands on the Wales-England border, and in the community of Maelor South. It lies south of the Llangollen Canal on the border with Shropshire, England within the historic English Maelor region which was formerly part of the historic county of Flintshire. The village lies close to Fenn's, Whixall and Bettisfield Mosses, an area of peat bog which was declared a national nature reserve in 1996 because of its importance for wildlife. The English market towns of Whitchurch, Ellesmere and Wem each lie about 6 miles distant to the northeast, west and southeast respectively. It is described in the Domesday book Domesday Book () – the Middle English spelling of "Doomsday Book" – is a manuscript record of the "Great Survey" of much of England and parts of Wales completed in 1086 by order of King William I, known as William the Conqueror.

Coal Seam
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to th ...

Bersham Colliery
Bersham Colliery was a large coal mine located near Rhostyllen in Wrexham County Borough, Wales. The mine accessed seams found in the Denbighshire Coalfield. History The Wrexham area in the 19th Century was highly industrialised. At the peak there were 38 different collieries operating in the area, each producing coal totalling over 2.5 million tonnes annually to the numerous brickworks and steelworks in the area, including Brymbo Steel Works and Shotton Steel Works. 19th century When the colliery first opened it was named Glan-yr-Afon ( en, Riverside) Colliery. Operated by Bersham Coal Company, the first shaft was sunk in 1864 on the site of a brickworks immediately adjacent to the Shrewsbury to Chester railway line, however due to difficulties the pit did not reach the main coal seams and the site was left abandoned until 1871 when the pit was deepened by new owners, the Barnes family of Liverpool; coal production started in 1874 with two shafts; No.1 at a diameter of 10 fe ...

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. History In north Wales, the Flintshire manors of Ewloe, Hopedale, and Mostyn and the Denbighshire manor of Brymbo were recorded as making profits from trading coal during the 14th and 15th centuries. By 1593, coal was exported from ports on the Dee estuary. Trade developed swiftly and by 1616, the principal collieries were at Bagillt, Englefield, Leaderbrook, Mostyn, Uphfytton and Wepre. Most were horizontal adits or shallow bell pits, although a few were sufficiently large to have accumulations of water and ventilation problems. In the Denbighshire Coalfield, the areas of ...

Flintshire Coalfield
The Flintshire Coalfield in north-east Wales is one of the smaller Great Britain, British coalfields. It is in the county of Flintshire and extends from the Point of Ayr in the north, along the Dee Estuary through Connah's Quay to Caergwrle in the south. A small part extends onto the Wirral Peninsula, Wirral i.e. England, English coast of the estuary at Neston, Cheshire which was the site of a coalmine for a period. The coal-bearing stratum, strata continue southwards of Caergwrle as the Denbighshire Coalfield. Together the two coalfields are known as the North Wales Coalfield. Geology Several coal seams are named in the sequence. Some seams are absent in the northern part of the coalfield and are labelled as (S) whilst the others occur across the coalfield as a whole. The Chwarelau Seam which appears only in the north actually occurs within the underlying Millstone Grit sequence rather than the Coal Measures proper. The seams are listed stratigraphically with the uppermost (young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oswestry
Oswestry ( ; ) is a market town, civil parish and historic railway town in Shropshire, England, close to the Welsh border. It is at the junction of the A5, A483 and A495 roads. The town was the administrative headquarters of the Borough of Oswestry until that was abolished in 2009. Oswestry is the third-largest town in Shropshire, following Telford and Shrewsbury. At the 2011 Census, the population was 17,105. The town is five miles (8 km) from the Welsh border and has a mixed English and Welsh heritage. Oswestry is the largest settlement within the Oswestry Uplands, a designated natural area and national character area. Toponym The name ''Oswestry'' is first attested in 1191, as ''Oswaldestroe''. This Middle English name transparently derives from the Old English personal name Ōswald and the word ''trēow'' ('tree'). Thus the name seems once to have meant 'tree of a man called Ōswald'.A. D.

Shropshire
Shropshire (; alternatively Salop; abbreviated in print only as Shrops; demonym Salopian ) is a landlocked historic county in the West Midlands region of England. It is bordered by Wales to the west and the English counties of Cheshire to the north, Staffordshire to the east, Worcestershire to the southeast, and Herefordshire to the south. A unitary authority of the same name was created in 2009, taking over from the previous county council and five district councils, now governed by Shropshire Council. The borough of Telford and Wrekin has been a separate unitary authority since 1998, but remains part of the ceremonial county. The county's population and economy is centred on five towns: the county town of Shrewsbury, which is culturally and historically important and close to the centre of the county; Telford, which was founded as a new town in the east which was constructed around a number of older towns, most notably Wellington, Dawley and Madeley, which is today th ...
