Lanterdan Quarry
Lanterdan Quarry is a disused open cast slate quarry between Tintagel and Trebarwith on the north coast of Cornwall, South West England. The quarry is the oldest, largest and most spectacular of Tintagel’s coastal quarries and was worked from the fifteenth until the early twentieth century. A distinguishing feature of the quarry is a 25m high pinnacle of inferior slate. Location The quarry lies south of Caroline Quarry immediately west of the village of Treknow. As the quarry is adjacent to Caroline and West quarries, it can be difficult to discern its exact boundaries. The quarry covers a 200m stretch of coastline but doesn’t reach as far as the water’s edge, making it more similar to the nearby inland workings at Prince of Wales and Bowithick quarries. The workings extend up to 80m inland and reach a height of around 30m. The quarry is clearly visible from the South West Coast Path and can also be reached by clambering over rocks from Trebarwith Strand and Hole b ...

South West Coast Path
The South West Coast Path is England's longest waymarked long-distance footpath and a National Trail. It stretches for , running from Minehead in Somerset, along the coasts of Devon and Cornwall, to Poole Harbour in Dorset. Because it rises and falls with every river mouth, it is also one of the more challenging trails. The total height climbed has been calculated to be 114,931 ft (35,031 m), almost four times the height of Mount Everest. It has been voted 'Britain's Best Walking route' twice in a row by readers of The Ramblers' ''Walk'' magazine, and regularly features in lists of the world's best walks. The final section of the path was designated as a National Trail in 1978. Many of the landscapes which the South West Coast Path crosses have special status, either as a national park or one of the heritage coasts. The path passes through two World Heritage Sites: the Dorset and East Devon Coast, known as the Jurassic Coast, was designated in 2001, and the Cornwall ...

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] |
Whim (mining)
A whim, also called a whim gin or a horse capstan, is a device similar to a windlass which is used in mining for hauling materials to the surface. It comprises a capstan or a wide drum with a vertical axle. A rope is wound around the drum, with both ends traversing several pulleys and hanging down the mine shaft. As the drum is turned around, one end of the rope is lowered, carrying an empty bucket, while the other one is raised, carrying a full load. The major benefit of a whim is that its operation can be performed at a distance from the shaft, thus resolving some of the congestion. Early whims were horse-powered, but later they were powered by waterwheels or steam engines, including the most advanced Cornish engines. Whims were used in coal mines until the end of the nineteenth century. Horse whims were also used to power team boats. The gin wheel at Nottingham Industrial Museum dating from 1844, is a wooden drum, set on a vertical pole within a wooden frame, with a horizont ...

Upper Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating al ...

Hole Beach
Hole Beach is a bathing and surf beach just north of Trebarwith Strand on the North Coast of Cornwall, South West England. The beach can be accessed from Trebarwith at low tide or by a zigzagging quarryman's track from the village of Treknow. The beach is sandy and the water is good for surfing Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitabl .... The sheer cliffs to the north of the beach form part of the now disused Caroline Slate Quarry and were created by quarrymen suspended by ropes attached to strongpoints some 75m on the clifftop above.«Coastal Slate Quarries – Tintagel to Trebarwith” (1990) Adam Sharpe, CAU archaeological survey for the National Trust.

Trebarwith Strand
Trebarwith Strand ( kw, Trebervedh Sian; locally sometimes shortened to ''The Strand'') is a section of coastline located near the coastal settlement of Trebarwith on the north coast of Cornwall, England, UK, south of Tintagel. It has 800m of sandy beach contained by cliffs in which natural caves are found. The beach can only be accessed at low tide. The strand was once used to land ships to export slate from the nearby quarries while sand from the beach was used for agricultural purposes. The view from the beach is dominated by rocks 300m offshore known as Gull Rock or Otterham Rocks. History The name Trebarwith was first associated with the village on the higher ground to the south of the valley which is the most southerly part of Tintagel parish. Land at Trebarwith is first mentioned in records of 1284 and was held from 1329 until the early 16th century by the Lercedekne family. Trebarwith Farm is a Grade II listed building.

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. This configuration, with the engine directly driving a pump, was first used by Thomas Newco ... located at the Prince of Wales quarry.

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 ...

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] |
