Mine Gallery
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great County Adit
The Great County Adit, sometimes called the County Adit, or the Great Adit was a system of interconnected adits that helped drain water from the tin and copper mines in the Gwennap area of Cornwall, in the United Kingdom. Construction started in 1748 and it eventually reached a length of over of a tunnel, providing drainage to over 100 mines at an average depth of . The adit was the brainchild of John Williams (born 1714) of Scorrier who was the manager of Poldice mine. Although work was started in 1748, it did not reach Poldice mine until the late 1760s. By 1778 the adit had been extended past Wheal Busy to Wheal Peevor, and another branch, known as the Consols Adit was driven west in the 1770s and 80s to drain the Consolidated Mines and United Mines. By 1792 a branch from Poldice extended to Wheal Unity. The portal of the adit is in the Carnon Valley below the hamlet of Twelveheads. In 1839, probably at its peak, it discharged over 14.5 million gallons (66 million litres) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hollingwood
Hollingwood is a small village approximately four miles north east of Chesterfield, Derbyshire, England. Description Hollingwood and Barrow Hill were built in c.1900 when the Staveley Coal and Iron Company formed and built homes there for the workers. It is alleged that Hollingwood was the first village in the country to have hot running water via a ring main from a central boiler house in the village. This boiler house was shut down in the very early 1980s when gas and electric boilers became readily available. It is surrounded by Brimington (where the population is included), Barrow Hill, and Inkersall. Between Barrow Hill and Hollingwood runs the Chesterfield Canal which is currently being regenerated by the Chesterfield Canal Trust. The canal house at Hollingwood has been renovated as a visitor centre and a very popular cafe, as well as being the headquarters of the Trust. The remains of the entrance to the Hollingwood Common Canal, originally a navigable adit, can still be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chesterfield Canal
The Chesterfield Canal is a narrow canal in the East Midlands of England and it is known locally as 'Cuckoo Dyke'. It was one of the last of the canals designed by James Brindley, who died while it was being constructed. It was opened in 1777 and ran for from the River Trent at West Stockwith, Nottinghamshire to Chesterfield, Derbyshire, passing through the Norwood Tunnel at Kiveton Park, at the time one of the longest tunnels on the British canal system. The canal was built to export coal, limestone, and lead from Derbyshire, iron from Chesterfield, and corn, deals, timber, groceries and general merchandise into Derbyshire. The stone for the Palace of Westminster was quarried in North Anston, Rotherham, and transported via the canal. It was reasonably profitable, paying dividends from 1789, and with the coming of the railways, some of the proprietors formed a railway company. It became part of the Manchester, Sheffield and Lincolnshire Railway company, and although there were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canal
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many ...

Hollingwood Common Canal
The Hollingwood Common Canal (alternatively the Hollingwood Common Canal Tunnel or the Hollingwood Common Tunnel) is a disused navigable coal mine adit which terminated at the Chesterfield Canal at Hollingwood, near Staveley, Derbyshire. History The Hollingwood Common canal tunnel was long, and measured high, with of water. Its water level was lower than that of the Chesterfield canal, requiring the trans-shipment of coal at a wharf constructed at the terminus. The water level in the tunnel was maintained lower than the canal by a culvert that ran beneath the canal. The wharf was on the old line of the Chesterfield Canal, prior to the 1892 cut being constructed. The entrance to the tunnel is still visible, though is gated off. Boats used were loaded underground within the coal mine the tunnel served; these boats were long and wide, and held seven cones or boxes containing twenty to twenty two hundredweight of coal each. Remains The wharf where the coal was transhipped was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mining In Cornwall And Devon
Mining in Cornwall and Devon, in the southwest of England, began in the early Bronze Age, around 2150 BC. Tin, and later copper, were the most commonly extracted metals. Some tin mining continued long after the mining of other metals had become unprofitable, but ended in the late 20th century. In 2021, it was announced that a new mine was extracting battery-grade lithium carbonate, more than 20 years after the closure of the last South Crofty tin mine in Cornwall in 1998. Historically, tin and copper as well as a few other metals (e.g. arsenic, silver, and zinc) have been mined in Cornwall and Devon. Tin deposits still exist in Cornwall, and there has been talk of reopening the South Crofty tin mine. In addition, work has begun on re-opening the Hemerdon tungsten and tin mine in south-west Devon. In view of the economic importance of mines and quarries, geological studies have been conducted; about forty distinct minerals have been identified from type localities in Cornwa ...

Virginia City
Virginia City is a census-designated place (CDP) that is the county seat of Storey County, Nevada, and the largest community in the county. The city is a part of the Reno– Sparks Metropolitan Statistical Area. Virginia City developed as a boomtown with the 1859 discovery of the Comstock Lode, the first major silver deposit discovery in the United States, with numerous mines opening. The population peaked in the mid-1870s, with an estimated 25,000 residents. The mines' output declined after 1878, and the population declined as a result. As of the 2020 Census, the population of Virginia City was 787. History Peter O'Riley and Patrick McLaughlin are credited with the discovery of the Comstock Lode. Henry T. P. Comstock's name was associated with the discovery through his own machinations. According to folklore, James Fennimore, nicknamed Old Virginny Finney, christened the town when he tripped and broke a bottle of whiskey at a saloon entrance in the northern section of Gol ...
