Great Western Mine
Great Western Mine, also known as Hetty Pit, was a coal mine, at Hopkinstown, near Pontypridd, Glamorgan in South Wales. History The mine was opened, as "Gyfeillon Pit", in August 1851 by John Calvert, an engineer from Yorkshire, who had already sunk the Newbridge Colliery (later to become part of the Maritime Collieries, near Graig, Pontypridd). In 1848 his money allowed the construction of the Gyfeillon Colliery to begin. The colliery changed hands to the Great Western Railway Company, reverting to Calvert, before he in turn sold it to the Great Western Colliery Company. The company would sink six shafts in total and the pits would collectively be known as the Great Western Collieries. The colliery initially had three shafts: Hetty Pit (downcast, later upcast), Pit No. 2 and Pit No. 3 (downcast). Hetty Shaft was sunk in 1875 to 392 yards. 1893 Disaster On Tuesday 11 April 1893 a fire in the colliery led to the deaths of 63 men and boys. The ages of the dead ranged from 1 ...

An electromagnetic coil is an electrical Electrical conductivity, conductor such as a wire in the shape of a wiktionary:coil, coil (spiral or helix). Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, Electric generator, generators, inductors, electromagnets, transformers, and sensor coils. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely, an external ''time-varying'' magnetic field through the interior of the coil generates an Electromotive force, EMF (voltage) in the conductor. A current through any conductor creates a circular magnetic field around the conductor due to Ampere's circuital law, Ampere's law. The advantage of using the coil shape is that it increases the strength of the magnetic field produced by a given current. The magnetic fields generated by the separate turns of wire all pass throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Lewis, 1st Baron Merthyr
William Thomas Lewis, 1st Baron Merthyr (5 August 1837 – 27 August 1914), known as Sir William Lewis, 1st Baronet, from 1896 to 1911, was a Welsh coal mining magnate. Early life Lewis was born in 1837 in Merthyr Tydfil, Glamorganshire, the second son of Thomas William Lewis, an engineer at the Plymouth, and his wife Mary Anne. He was educated at a local school run by Taliesin Williams until the age of thirteen when he was apprenticed to his father as an engineer. In 1855 Lewis was appointed as an assistant to W. S. Clark, the chief mining engineer of John Crichton-Stuart, 3rd Marquess of Bute (1847–1890). He spent ten years in that post before succeeding Clark in 1864. Lewis was given the occupancy of Mardy House as part of his job, which became his long-term residence in Aberdare. The same year he married Anne Rees, daughter of William Rees, and granddaughter of Lucy Thomas, the legendary "mother of the Welsh steam-coal trade". Lewis and Anne had two sons and six daught ...

Coal Mining Disasters In Wales
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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scheduled Monuments In Wales
Scheduled monuments (also known as scheduled ancient monuments, or SAMs) are sites of archaeological importance with specific legal protection against damage or development. The list of such monuments in Wales is maintained by Cadw: Welsh Historic Monuments, an executive agency within the Welsh National Assembly. there were 4,186 scheduled monuments in Wales, distributed among all 22 principal areas of Wales. 39 sites cross a border between two authorities, (ridge-top cairns, bridges and aqueducts, cross dykes, tramroads) so are included in both lists. The lists below show these sites, arranged by principal areas (counties and county boroughs), and in the case of the larger counties, sub-divided to maintain a manageable number of sites per page.

Collieries In South Wales
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to the ...

Buildings And Structures In Rhondda Cynon Taf
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhondda Heritage Park
Rhondda Heritage Park, Trehafod, Rhondda, South Wales is a tourist attraction which offers an insight into the life of the coal mining community that existed in the area until the 1980s. Visitors can experience the life of the coal miners on a guided tour through one of the mine shafts of the Lewis Merthyr colliery. Tours are led by former colliery workers. Rhondda Heritage Park is an Anchor Point of ERIH, The European Route of Industrial Heritage. Rhondda Heritage Park exists on the site of the former Lewis Merthyr Colliery as a testament to the coal mining history of the Rhondda Valleys, which until the end of the 20th century was one of the most important coal mining areas in the world - in an area only long, Rhondda alone had over 53 working collieries at one time. History of the Lewis Merthyr Colliery Although coal was mined as early as the seventeenth century in the Rhondda for domestic purposes, the earliest recorded opening and mining of a safe coal level was in 1790 b ...

Grade II* Listed
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland.

The statutory term in Ireland is "Record of Protected Structures, protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings.
