Bowithick Quarry
Bowithick Quarry is a disused nineteenth century open cast slate quarry situated in Trebarwith Valley on the outskirts of Tintagel in Cornwall, South West England. The quarry ceased operations in 1913. Location The quarry site lies in Trebarwith valley between the hamlets of Trewarmett and Penpethy and can be accessed from the B3263 road. History Bowithick quarry lies at the eastern end of the Prince of Wales Quarry and the two appear to have been worked in tandem. Slate from both quarries was dressed at Bowithick with the finished stone being hauled back across the valley using power from the Woolf Compound beam engine A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod.

Open-pit
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock (geology), rock or minerals from the earth from an open-air pit, sometimes known as a Borrow pit, borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in t ...

Tintagel
Tintagel () or Trevena ( kw, Tre war Venydh, meaning ''Village on a Mountain'') is a civil parish and village situated on the Atlantic coast of Cornwall, England. The village and nearby Tintagel Castle are associated with the legends surrounding King Arthur and in recent times has become a tourist attraction. Toponymy Toponymists have had difficulty explaining the origin of 'Tintagel': the probability is that it is Norman French, as the Cornish of the 13th century would have lacked the soft 'g' ('i/j' in the earliest forms: see also Tintagel Castle). If it is Cornish then 'Dun' would mean ''Fort''. Oliver Padel proposes 'Dun' '-tagell' meaning ''narrow place'' in his book on place names. There is a possible cognate in the Channel Islands named ''Tente d'Agel'', but that still leaves the question subject to doubt. The name first occurs in Geoffrey of Monmouth's ''Historia Regum Britanniae'' (c. 1136, in Latin) as ''Tintagol'', implying pronunciation with a hard sound as in ...

Cornwall
Cornwall (; kw, Kernow ) is a historic county and ceremonial county in South West England. It is recognised as one of the Celtic nations, and is the homeland of the Cornish people. Cornwall is bordered to the north and west by the Atlantic Ocean, to the south by the English Channel, and to the east by the county of Devon, with the River Tamar forming the border between them. Cornwall forms the westernmost part of the South West Peninsula of the island of Great Britain. The southwesternmost point is Land's End and the southernmost Lizard Point. Cornwall has a population of and an area of . The county has been administered since 2009 by the unitary authority, Cornwall Council. The ceremonial county of Cornwall also includes the Isles of Scilly, which are administered separately. The administrative centre of Cornwall is Truro, its only city. Cornwall was formerly a Brythonic kingdom and subsequently a royal duchy. It is the cultural and ethnic origin of the Cornish dias ...

Trewarmett
Trewarmett ( kw, Trewerman) is a small hamlet in Cornwall, England, United Kingdom. It lies within the civil parish of Tintagel, 3 miles (5 km) north-west of Camelford. To the west of Trewarmett is Trebarwith Nature Reserve. Trewarmett lies within the Cornwall Area of Outstanding Natural Beauty (AONB). There was formerly a Methodist church in Trewarmett; the Methodist cemetery is nearby. The Trebarwith valley nearby was used for slate mining in the 19th century. The Prince of Wales Engine House was built in 1871 to transport slate and water from the quarries towards Tintagel. The engine house fell into disrepair and was restored by the local Prince of Wales Engine House Society. In 2014, the Prince of Wales Prince of Wales ( cy, Tywysog Cymru, ; la, Princeps Cambriae/Walliae) is a title traditionally given to the heir apparent to the English and later British throne.

The Prince Of Wales Quarry
The Prince of Wales Quarry is a disused open cast slate quarry in Trebarwith Valley on the outskirts of Tintagel in Cornwall, South West England. The quarry is known for its engine house, the only one of its kind in North Cornwall. History The quarry was opened in 1871 but closed during the 1890s. It has now fallen into disrepair. The engine house was built in 1870 and is believed to have remained in operation until nearby Bowithick Quarry closed down in 1913. It was restored in 1976. The quarry pit is now flooded creating a small lake. The Engine House The dominant feature of the quarry is its stone engine house. Built in 1870, this served a dual purpose of pumping and winding. The engine house was built to accommodate a 50" Woolf Compound beam engine which pumped the large pit below and hauled large blocks of slate from the depths of the quarry workings to the headframe where it was sorted ready for splitting. The engine also hauled trucks across bridges from Bowthick q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Beam Engine
A beam engine is a type of steam engine where a pivoted overhead beam is used to apply the force from a vertical piston to a vertical connecting rod. This configuration, with the engine directly driving a pump, was first used by Thomas Newcomen around 1705 to remove water from mines in Cornwall. The efficiency of the engines was improved by engineers including James Watt, who added a separate condenser; Jonathan Hornblower and Arthur Woolf, who compounded the cylinders; and William McNaught, who devised a method of compounding an existing engine. Beam engines were first used to pump water out of mines or into canals but could be used to pump water to supplement the flow for a waterwheel powering a mill. The rotative beam engine is a later design of beam engine where the connecting rod drives a flywheel by means of a crank (or, historically, by means of a sun and planet gear). These beam engines could be used to directly power the line-shafting in a mill. They also c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine House
__NOTOC__ An engine house is a building or other structure that holds one or more engines. It is often practical to bring engines together for common maintenance, as when train locomotives are brought together. Types of engine houses include: * motive power depots (MPD), where locomotives are stored and maintained * Buildings that housed a steam engine on a mine. Many of these have survived in Cornwall, England, for example at Crown Mines * Buildings that housed a pumping engine for an atmospheric railway *House-built engines, where the engine ''is'' the house. A house-built engine is a large beam engine where the engine house itself forms the frame of the engine. *Fire stations, which hold fire engine trucks, are often termed engine houses, perhaps especially in United States. Examples Notable examples, not including fire stations, include: ;in Australia *Numerous historic sites listed on the Victoria Heritage Register ;in England: * The South Devon Railway engine houses, buil ...

Quarries In Cornwall
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal *Construction aggregate (sand and gravel) *Coquina *Diabase *Gabbro *Granite *Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operations was ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
