Cymmer Colliery Explosion
The Cymmer Colliery explosion occurred in the early morning of 15 July 1856 at the Old Pit mine of the Cymmer, Rhondda Cynon Taf, Cymmer Coal mining, Colliery near Porth (lower Rhondda, Rhondda Valley), Wales, operated by George Insole & Son. The underground gas explosion resulted in a "sacrifice of human life to an extent unparalleled in the history of coal mining of this country" in which 114 men and boys were killed. Thirty-five widows, ninety-two children, and other dependent relatives were left with no immediate means of support. The immediate cause of the explosion was defective Underground mine ventilation, mine ventilation and the use of naked flames underground. Factors contributing to the explosion included the rapid development of the mine to meet increased demand for coal, poor mine safety practices allowed by management despite official warnings, and deteriorating working relationships between miners and management. After the explosion, mine owner James Harvey I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porth
Porth ( cy, Y Porth) is a town and a community in the county borough of Rhondda Cynon Taf, within the historic county boundaries of Glamorgan, Wales. Lying in the Rhondda Valley, it is regarded as the gateway connecting the Rhondda Fawr and Rhondda Fach valleys due to both valleys meeting at Porth. The Welsh word "porth" means "gate". Porth is a predominantly English-speaking community. Neighbouring villages include Trealaw, Trebanog, Trehafod and Ynyshir. History Early history During prehistoric times the area now known as Porth was an uninhabited wooded area. Although there is evidence of settlements in the upper reaches of the valley, only cairns used as way-markers have been discovered on the higher points in the Porth area. During the medieval period the area came under the commote of Glynrhondda within the cantref of Penychen, though the area remained uninhabited. Although there were no permanent buildings of note at this time, it is known that the area would have expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Labour Law In The United Kingdom
The History of labour law in the United Kingdom concerns the development of UK labour law, from its roots in Roman and medieval times in the British Isles up to the present. Before the Industrial Revolution and the introduction of mechanised manufacture, regulation of workplace relations was based on status, rather than contract or mediation through a system of trade unions. Serfdom was the prevailing status of the mass of people, except where artisans in towns could gain a measure of self-regulation through guilds. In 1740 save for the fly- shuttle the loom was as it had been since weaving had begun. The law of the land was, under the Act of Apprentices 1563, that wages in each district should be assessed by Justices of the Peace. From the middle of the 19th century, through Acts such as the Master and Servant Act 1867 and the Employers and Workmen Act 1875, there became growing recognition that greater protection was needed to promote the health and safety of workers, as well as p ...

Afterdamp
Afterdamp is the toxic mixture of gases left in a mine following an explosion caused by methane-rich firedamp, which itself can initiate a much larger explosion of coal dust. The term is etymologically and practically related to other terms for underground mine gases—such as firedamp, white damp, and black damp, with afterdamp being composed, rather, primarily by carbon dioxide, carbon monoxide and nitrogen, with highly toxic stinkdamp-constituent hydrogen sulfide possibly also present. However, the high content of carbon monoxide is the component that kills, preferentially combining with haemoglobin in the blood and thus depriving victims of oxygen. Globally, afterdamp has caused many of the casualties in disasters of pit coalfields, including British, such as the Senghenydd colliery disaster. Such disasters continue to afflict working mines, for instance in mainland China. Etymology The meaning of "damp" in this term, while most commonly understood to imply humidity, presents e ...

Geordie Lamp
The Geordie lamp was a safety lamp for use in flammable atmospheres, invented by George Stephenson in 1815 as a miner's lamp to prevent explosions due to firedamp in coal mines. Origin In 1815, Stephenson was the engine-wright at the Killingworth Colliery in Northumberland and had been experimenting for several years with candles close to firedamp emissions in the mine. In August he ordered an oil lamp which was delivered on 21 October and tested by him in the mine in the presence of explosive gases. He improved this over several weeks with the addition of capillary tubes at the base so that it gave more light and tried new versions on 4 and 30 November. This was presented to the Literary and Philosophical Society (Lit & Phil) of Newcastle upon Tyne on 5 December 1815. Although controversy arose between Stephenson's design and the Davy lamp (invented by Humphry Davy in the same year), Stephenson's original design worked on significantly different principles from Davy's final d ...

Secretary Of State (United Kingdom)
His Majesty's principal secretaries of state, better known as secretaries of state, are senior ministers of the Crown in the Government of the United Kingdom. Secretaries of state head most major government departments and make up the majority of the Cabinet of the United Kingdom. There are currently 16 secretaries of state. They are all also currently members of Parliament elected to the House of Commons, although it is possible for them to be members of the House of Lords. Legal position Under the Ministerial and other Salaries Act 1975, a maximum of 21 secretaries of state can receive a salary. Legislation generally refers simply to "the secretary of state" without further elaboration. By virtue of the Interpretation Act 1978, this phrase means "one of His Majesty’s Principal Secretaries of State". Despite there only being one secretary of state in law, in practice, each secretary of state will perforce stay within their own portfolio. Secretaries of state, like other ...

Rivington (publishers)
Rivington, or Rivington's, also called Rivington & Co., was a London-based publishing company founded by Charles Rivington (1688–1742), originally from Derbyshire, and continued by his sons and grandsons. History In 1736 Charles Rivington and a partner called Bettesworth founded a company of booksellers called "The New Conger", rivalling an older firm called "The Conger" that dated from about 1700. From selling books, Rivington moved on to the business of publishing books. In 1741 he published the first volume of Samuel Richardson's novel ''Pamela, or Virtue Rewarded''. Both men were from Derbyshire, and Rivington had persuaded Richardson to write a novel in the form of a correspondence.Septimus Rivington, ''The House of Rivington'' (1894) After his death in 1742, Charles Rivington was succeeded by his two sons, John (1720–1792) and James Rivington (1724–1802).

Coal Thrusters & Trapper (Cobden 1854)
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crimean War
The Crimean War, , was fought from October 1853 to February 1856 between Russia and an ultimately victorious alliance of the Ottoman Empire, France, the United Kingdom and Piedmont-Sardinia. Geopolitical causes of the war included the decline of the Ottoman Empire, the expansion of the Russian Empire in the preceding Russo-Turkish Wars, and the British and French preference to preserve the Ottoman Empire to maintain the balance of power in the Concert of Europe. The flashpoint was a disagreement over the rights of Christian minorities in Palestine, then part of the Ottoman Empire, with the French promoting the rights of Roman Catholics, and Russia promoting those of the Eastern Orthodox Church. The churches worked out their differences with the Ottomans and came to an agreement, but both the French Emperor Napoleon III and the Russian Tsar Nicholas I refused to back down. Nicholas issued an ultimatum that demanded the Orthodox subjects of the Ottoman Empire be placed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgical Coal
Metallurgical coal or coking coal is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply. Metallurgical coal comes mainly from Canada, the United States, and Australia, with Australia exporting 58% of seaborne trade, mostly going to China. In the United States, the electric power sector used "93% of total U.S. coal consumption between 2007 and 2018"; only 7% of the total was metallurgical coal and coal for other uses such as heating. Characteristics Metallurgical coal is low in ash, moisture, sulfur and phosphorus content, and its rank is usually bituminous. Some grades of anthracite coal are used for sintering, pulverized coal injection, direct blast furnace charge, pelletizing ...

Miners
A miner is a person who extracts ore, coal, chalk, clay, or other minerals from the earth through mining. There are two senses in which the term is used. In its narrowest sense, a miner is someone who works at the rock face; cutting, blasting, or otherwise working and removing the rock. In a broader sense, a "miner" is anyone working within a mine, not just a worker at the rock face. Mining is one of the most dangerous trades in the world. In some countries, miners lack social guarantees and in case of injury may be left to cope without assistance. In regions with a long mining tradition, many communities have developed cultural traditions and aspects specific to the various regions, in the forms of particular equipment, symbolism, music, and the like. Roles Different functions of the individual miner. Many of the roles are specific to a type of mining, such as coal mining. Roles considered to be "miners" in the narrower sense have included: *Hewer (also known as "cake" or "pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
