Consolidated Mines
Consolidated Mines, also known as Great Consolidated mine, but most commonly called Consols or Great Consols was a metalliferous mine about a mile ESE of the village of St Day, Cornwall, England. Mainly active during the first half of the 19th century, its mining sett was about 600 yards north–south; and 2,700 yards east–west, to the east of Carharrack. Although always much troubled by underground water, the mine was at times highly profitable, and it was the largest single producer of copper ore in Cornwall. Today the mine is part of the Cornwall and West Devon Mining Landscape World Heritage Site. Geology The country rock at the mine was killas and the mine's main produce was copper, though small amounts of black tin, arsenic, pyrite and zinc ore were also raised. There are about eight main lodes at the mine, crossed by elvan dykes. The most important lode was Virgin Lode which was stoped for over .Dines 1956, p.418 History to 1800 Although there had been mini ...

Wheal Maid
Wheal Maid (also Wheal Maiden) is a former mine in the Camborne-Redruth-St Day Mining District, 1.5 km east of St Day. Between 1800 and 1840, profits are said to have been up to £200,000. In 1852, the mine was amalgamated with Poldice Mine and Carharrack Mine and worked as St Day United mine. Throughout the 1970s and 1980s, the mine site was turned into large lagoons and used as a tip for two other nearby mines: Mount Wellington and Wheal Jane. There were suggestions that the mine could be used as a landfill site for rubbish imported from New York and a power plant that would produce up to 40 megawatts of electricity; the concept was opposed by local residents and by Cornwall County Council, with Doris Ansari, the chair of the council's planning committee, saying that the idea " idnot seem right for Cornwall". The site was bought from Carnon Enterprises by Gwennap District Council for a price of £1 in 2002. An investigation by the Environment Agency that concluded in ...

Stoping (mining Method)
Stoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided. The earliest forms of stoping were conducted with hand tools or by fire-setting; later gunpowder was introduced. From the 19th century onward, various other explosives, power-tools, and machines came into use. As mining progresses the stope is often backfilled with tailings, or when needed for strength, a mixture of tailings and cement. In old mines, stopes frequently collapse at a later time, leaving craters at the surface. They are an unexpected danger when records of underground mining have been lost with the passage of time. Stoping is considered "productive work", and is contrasted with "deadwork", the work required merely to access the mineral deposit, such as sinking shafts and winz ...

Devoran
Devoran ( kw, Deveryon) is a village in south Cornwall, England, United Kingdom. It is southwest of Truro at .Ordnance Survey: Landranger map sheet 204 ''Truro & Falmouth'' Formerly an ecclesiastical parish, Devoran is now in the civil parish of Feock (where the 2011 census population is included). The village is on the northeast bank of the Carnon River at its confluence with Restronguet Creek, a tidal creek which flows into Carrick Roads above Falmouth. Devoran is at the Normal Tidal Limit (NTL) of the creek but until the 20th-century the tidal limit stretched much further up the valley than now.Cornwall Industrial Settlements Initiative; Devoran PDF.

Redruth And Chasewater Railway
The Redruth and Chasewater Railway, (otherwise called the ''Redruth and Chacewater Railway'' using modern spelling), was an early mineral railway line in Cornwall, England, UK. It opened in 1825 and was built to convey the output from copper mines in the Gwennap area to wharves on Restronguet Creek (off the Fal Estuary) around Devoran, and to bring in coal to fuel mine engines; later it carried timber for pit props and also house coal. A little over long, it was built to a narrow gauge and used horse traction at first, later using steam locomotives. Solely dependent on the economy of the mines it served, it prospered when they did, and when they declined, the railway declined too; it finally closed in 1915. It never carried passengers. Much of its route can still be traced, and part of it forms the course of the Redruth and Chasewater Railway Trail, an outdoor leisure facility. History Antecedents Prior to the nineteenth century, much mineral extraction had taken place in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neath Abbey Ironworks
Neath Abbey ( cy, Abaty Nedd) was a Cistercian monastery, located near the present-day town of Neath in South Wales, UK. It was once the largest abbey in Wales. Substantial ruins can still be seen, and are in the care of Cadw. Tudor historian John Leland called Neath Abbey "the fairest abbey of all Wales." Neath Abbey is also the name of an area of Neath near to the abbey ruins. History Neath Abbey was established in 1129 AD when Richard I de Grenville (d.post 1142), one of the Twelve Knights of Glamorgan, gave of his estate in Glamorgan, Wales, to Savigniac monks from western Normandy. The first monks arrived in 1130. Following the assumption of the Savigniac order into the Cistercian order in 1147, Neath Abbey also became a Cistercian house. The abbey was ravaged by the Welsh uprisings of the 13th century. During the Dissolution of the Monasteries by King Henry VIII of England the last abbot, Lleision ap Thomas, managed to buy time through payment of a large fine in ...

Arthur Woolf
Arthur Woolf (1766, Camborne, Cornwall – 16 October 1837, Guernsey) was a Cornish engineer, most famous for inventing a high-pressure compound steam engine. As such he made an outstanding contribution to the development and perfection of the Cornish engine. Woolf left Cornwall in 1785 to work for Joseph Bramah's engineering works in London. He worked there and at other firms as an engineer and engine builder until 1811 experimenting with high pressure steam and a much improved boiler. Whereupon he returned to Cornwall. Michael Loam, inventor of the man engine, was trained by him. When he returned to Cornwall, beam engine designs were crude, shackled by outdated James Watt, Watt patents and poor engineering, struggling to compete with large water wheels, even used underground. He learned from Bramah that to move forward meant adopting much improved engineering techniques, for it was Bramah who invented quality control. Woolf was chief engineer to Harvey & Co of Hayle, the le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Taylor (civil Engineer)
John Taylor (22 August 1779, in Norwich – 5 April 1863, in London) was a British mining engineer. Life Taylor was the son of John and Susannah Taylor. He was the brother of Philip Taylor. Business interests Many of Taylor’s business interests were backed by the Martineau family. In 1796 he improvised a mechanised copper ore crusher at Wheal Friendship, a mine just outside Tavistock, Devon. This machine was improved over time and became widely adopted; it was known as the "Cornish rolls". Two years later, in 1798, when he was only 19 years old, he became the manager of this mine. Taylor’s sons and Peter Finch Martineau’s son and grandson were still active in its operations and oversight nearly a century later. From 1803 to 1817 Taylor oversaw the construction of the Tavistock Canal, which linked the town of Tavistock to Morwellham Quay on the River Tamar, where cargo was loaded into ships. In 1812 Taylor set up as a chemical manufacturer at Stratford, Essex. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Downs Mine
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parys Mountain
Parys Mountain ( cy, Mynydd Parys) is located south of the town of Amlwch in north east Anglesey, Wales. It is the site of a large copper mine that was extensively exploited in the late 18th century. Parys Mountain is a mountain in name only, being a hill with an elevation of barely 150m. History Parys Mountain was mined for copper ore in the early Bronze Age, as shown by sub-surface debris nearly 4,000 years old revealed during excavations in 2002. Since then access has been regained to the sealed underground workings of the Parys mine revealing further evidence for this ancient mining. Parys Mountain is thus one of the few sites in Britain where there is evidence for the prehistoric beginnings of the British metal mining industry. The 18th century miners recognised that they were following in the steps of much earlier workers, an observation that was then linked to the discovery locally of copper ingots bearing Roman inscriptions. In 1764 Charles Roe of Macclesfield was gran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winding Engine
A winding engine is a stationary engine used to control a cable, for example to power a mining hoist at a pit head. Electric hoist controllers have replaced proper winding engines in modern mining, but use electric motors that are also traditionally referred to as ''winding engines''. Early winding engines were hand, or more usually horse powered. The first powered winding engines were stationary steam engines. The demand for winding engines was one factor that drove James Watt to develop his rotative beam engine, with its ability continuously to turn a winding drum, rather than the early reciprocating beam engines that were only useful for working pumps. They differ from most other stationary steam engines in that, like a steam locomotive, they need to be able to stop frequently and also reverse. This requires more complex valve gear and other controls than are needed on engines used in mills or to drive pump A pump is a device that moves fluids (liquids or gases), or ...

Boulton And Watt
Boulton & Watt was an early British engineering and manufacturing firm in the business of designing and making marine and stationary steam engines. Founded in the English West Midlands around Birmingham in 1775 as a partnership between the English manufacturer Matthew Boulton and the Scottish engineer James Watt, the firm had a major role in the Industrial Revolution and grew to be a major producer of steam engines in the 19th century. The engine partnership The partnership was formed in 1775 to exploit Watt's patent for a steam engine with a separate condenser. This made much more efficient use of its fuel than the older Newcomen engine. Initially the business was based at the Soho Manufactory near Boulton's Soho House on the southern edge of the then-rural parish of Handsworth. However most of the components for their engines were made by others, for example the cylinders by John Wilkinson. In 1795, they began to make steam engines themselves at their Soho Foundry in ...
