Minera Lead Mines
The Minera Lead Mines were a mining operation and are now a country park and tourist centre in the village of Minera near Wrexham, in Wrexham County Borough, Wales. History The first written record of lead mining at Minera dates back to 1296, when Edward I of England hired miners from the site to work in his new mines in Devon. Not all of them vacated the area, however, as mining went on until the Black Death in 1349, when it ended. In 1527, two men bought the rights to mine on the site, but deeper workings were unworkable due to the presence of underground rivers, and the inability to prevent flooding. The inability to pay for steam engines to pump out water closed the mines again until 1845, when John Taylor & Sons, mining agents from Flintshire, formed the Minera Mining Company. They were able to build a stationary steam engine on site, and also blast caves from down in the valley into the mines, for extra drainage. The steam engine was a Cornish engine (i.e. a Beam engine) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meadow Shaft
A meadow ( ) is an open habitat, or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as these areas maintain an open character. Meadows may be naturally occurring or artificially created from cleared shrub or woodland. They can occur naturally under favourable conditions (see perpetual meadows), but they are often maintained by humans for the production of hay, fodder, or livestock. Meadow habitats, as a group, are characterized as "semi-natural grasslands", meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife, and support flora and fauna that could not thrive in other habitats. They are ecologically important as they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering, if the vegetation is high enough. There are multiple types of meadows, i ... [...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] |
Mining Museums In Wales
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and f ...

Mining In Wales
Mining in Wales provided a significant source of income to the economy of Wales throughout the nineteenth century and early twentieth century. It was key to the Industrial Revolution. Wales was famous for its coal mining, in the Rhondda Valley, the South Wales Valleys and throughout the South Wales coalfield and by 1913 Barry had become the largest coal exporting port in the world, with Cardiff as second, as coal was transported down by rail. Northeast Wales also had its own coalfield and Tower Colliery (closed January 2008) near Hirwaun is regarded by many as the oldest open coal mine and one of the largest in the world. Wales has also had a significant history of mining for slate, gold and various metal ores. History There had been small-scale mining in Wales in the pre-Roman British Iron Age, but it would be undertaken on an industrial scale under the Romans, who completed their conquest of Wales in AD 78. Substantial quantities of gold, copper, and lead were extracted, alon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wrexham County Borough Council
Wrexham County Borough Council () is the governing body for Wrexham County Borough, a Principal area of Wales, principal area in North Wales, north Wales, covering Wrexham and the surrounding area. History Elections take place every five years. The Welsh Labour Party, Labour Party held power on the council after the 2012 election, but lost it after splitting because of an internal row. Several Labour councillors became independent, allowing the Independent (politician), Independent group to take control in alliance with the Welsh Conservative Party, Conservatives. At the 2017 Wrexham County Borough Council election, 2017 election, the independents retained their dominance. A coalition of the Independent group, the Wrexham Independents group and the Conservatives agreed to run the council for the next 5 years to 2022. On 28 November 2018 Councillor Paul Rogers left the Conservative Group to become non-aligned. He then went on to join the Independent group on 15 May 2019. On 7 No ...

Narrow Gauge Railway
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manning Wardle
Manning Wardle was a steam locomotive manufacturer based in Hunslet, Leeds, West Yorkshire, England. Precursor companies The city of Leeds was one of the earliest centres of locomotive building; Matthew Murray built the first commercially successful steam locomotive, ''Salamanca'', in Holbeck, Leeds, in 1812. By 1856, a number of manufacturers had sprung up in the city, including Kitson and Company, and E. B. Wilson and Company, later The Railway Foundry after 1848. Manning Wardle The Railway Foundry (E.B Wilson from 1838-48) operated in Leeds until 1858. At least some of the company's designs and some materials were purchased by Manning Wardle & Company, who located their Boyne Engine Works in Jack Lane in the Hunslet district of the city. Steam locomotive construction commenced on the site in 1859. Within the next few years, two other companies, the Hunslet Engine Company and Hudswell, Clarke & Company also opened premises in Jack Lane. There was a good deal of st ...

Minera Limeworks
The Minera Limeworks were extensive lime quarries and kilns at Minera in Wrexham, Wales. It was located at , near the villages of Gwynfryn, Minera, and Coedpoeth and was locally referred to as ''The Calch''. History The Minera Limeworks were once the largest lime workings in the north of Wales. Limeburning at Minera is recorded from as early as 1620 but the Minera Lime Company was established in 1852. The total output from the Minera area quarries was estimated, in 1859, to be around 300,000 tons, with 200,000 tons of this converted to lime. The Minera Lime Company became a limited company in 1865, and this prompted some heavy cash injection into the works. Using this money, the company erected a "Hoffmann kiln". Originally destined for brickmaking, it was soon converted to limeburning. This kiln still exists and is one of three that were purpose-built for lime burning left in the UK: another is located at Langcliffe in Yorkshire, another is located at Llanymynech Limew ...

Wrexham And Minera Branch
The Wrexham and Minera Railway or Wrexham and Minera Branch was a railway line in North Wales between the city of Wrexham, the village of Brymbo where it served the Brymbo Steelworks, and the lead mines and Minera Limeworks, limeworks at Minera. A further branch ran from Brymbo to Coed Talon, where it connected with lines to Mold, Flintshire, Mold. The system was constructed in several stages between 1844 and 1872, while the various lines making up the system closed in 1952, 1972 and 1982. A directly competing route to Brymbo was opened by the Wrexham, Mold and Connah's Quay Railway in the 1880s. It closed in stages between 1954 and 1970. History The railway was one of several constructed to serve the intensive quarrying, mining and iron founding operations in the area west of Wrexham, which were undergoing considerable expansion in the mid 19th century thanks to exploitation of the underlying Middle Coal Measures. Construction The section of line between Brymbo and Minera h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornish Engine
A Cornish engine is a type of steam engine developed in Cornwall, England, mainly for pumping water from a mine. It is a form of beam engine that uses steam at a higher pressure than the earlier Watt steam engine, engines designed by James Watt. The engines were also used for powering man engines to assist the underground miners' journeys to and from their working levels, for winching materials into and out of the mine, and for powering on-site stamp mill, ore stamping machinery. Background: The steam engine in Cornwall Cornwall has long had tin, copper and other metal ore mines, but if mining is to take place at greater depths, a means to dewatering, dewater the mine must be found. Lifting the weight of water up from the depths requires great amounts of work (physics), work input. This energy may be weakly supplied by horse power or a waterwheel to operate pumps, but horses have limited power and waterwheels need a suitable stream of water. Accordingly, the innovation of c ...
