Winsford Mine
Winsford Mine (also known as Meadow Bank Mine) is a halite (rock salt) mine in the town of Winsford, Cheshire, England. The mine produces an average of of rock salt a year, which is used to grit public roads in the United Kingdom during the winter months. Two other mines also produce rock salt within the United Kingdom, but Winsford has the biggest output of all three and has the largest market share. It is also Britain's oldest working mine. History The salt in the area was discovered by accident when workers were looking for coal reserves to heat saltpans. It was opened out in 1844, but a downturn in the rock salt market led to its closure in 1892. It was re-opened in 1928 when a nearby salt mine, the Marston Mine in Northwich, was subjected to flooding after subsidence. The salt was laid down during the Triassic period over 220 million years ago when the area was under a tropical sea, and later a briny lagoon. Reserves in the mine area have an estimated life until the yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winsford
Winsford is a town and civil parishes in England, civil parish in the unitary authority of Cheshire West and Chester and the ceremonial county of Cheshire, England, on the River Weaver south of Northwich and west of Middlewich. It grew around the Salt mine, salt mining industry after the river was canalised in the 18th century, allowing freight to be conveyed northwards to the Port of Runcorn on the River Mersey. Winsford is split into three areas: Over, Cheshire, Over on the western side of the River Weaver, Wharton on the eastern side, and Swanlow and Dene. History Early origins Winsford consists of three ancient parishes, St Chads, Over and Wharton, which in the 19th century were combined. The name “Winsford” is of uncertain origin but is thought to derive from Wain’s or Wynne’s and Ford (Mr Wain's crossing point of the river Weaver). The Norman Earl of Chester, Earls of Chester had a hunting lodge or summer palace at Darnhall in Over, Cheshire, Over parish. The ...

Halite
Halite (), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride ( Na Cl). Halite forms isometric crystals. The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on inclusion of other materials, impurities, and structural or isotopic abnormalities in the crystals. It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates. The name ''halite'' is derived from the Ancient Greek word for "salt", ἅλς (''háls''). Occurrence Halite dominantly occurs within sedimentary rocks where it has formed from the evaporation of seawater or salty lake water. Vast beds of sedimentary evaporite minerals, including halite, can result from the drying up of enclosed lakes and restricted seas. Such salt beds may be hundreds of meters thick and underlie broad areas. Halite occurs at the surface today in playas in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salt Pan (evaporation)
A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines. The Salt pans are shallow and large of size because it will be easier for sunlight to travel and reach the sea water. Natural salt pans are geological formations that are also created by water evaporating and leaving behind salts. Some salt evaporation ponds are only slightly modified from their natural version, such as the ponds on Great Inagua in the Bahamas, or the ponds in Jasiira, a few kilometres south of Mogadishu, where seawater is trapped and left to evaporate in the sun. The seawater or brine is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be subsequently harvested. The ponds also provide a productive resting and feeding ground for many species of waterbirds, which may include endangered species. The ponds are commonly separated by levees. Salt evaporation ponds may also be called salterns, salt works o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago (Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Room And Pillar Mining
Room and pillar or pillar and stall is a variant of breast stoping. It is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof overburden. Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of active research. The technique is usually used for relatively flat-lying deposits, such as those that follow a particular stratum. Room and pillar mining can be advantageous because it reduces the risk of surface subsidence compared to other underground mining techniques. It is also advantageous because it can be mechanized, and is relatively simple. However, because significant portions of ore may have to be left behind, recovery and profits can be low. Room and pillar mining was one of the earliest methods used, although with significantly more man-power. The roo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Of 2009–10 In Great Britain And Ireland
The winter of 2009–10 in the United Kingdom (also called ''The Big Freeze of 2010'' by British media) was a meteorological event that started on 16 December 2009, as part of the severe winter weather in Europe. January 2010 was provisionally the coldest January since 1987 in the UK. A persistent pattern of cold northerly and easterly winds brought cold, moist air to the United Kingdom with many snow showers, fronts and polar lows bringing snowy weather with it. The first snow fell on 17 December 2009, before a respite over the Christmas period. The most severe snowy weather began on 5 January in North West England and west Scotland with temperatures hitting a low of in Greater Manchester, England. The snow spread to Southern England on 6 January and by 7 January the United Kingdom was blanketed in snow, which was captured by NASA's Terra satellite. The thaw came a week later, as temperatures started to increase. The winter weather brought widespread transport disruption, s ...

The National Archives (United Kingdom)
The National Archives (TNA, cy, Yr Archifau Cenedlaethol) is a non-ministerial government department, non-ministerial department of the Government of the United Kingdom. Its parent department is the Department for Digital, Culture, Media and Sport of the United Kingdom of Great Britain and Northern Ireland.
