Mining Accident
A mining accident is an accident that occurs during the process of mining minerals or metals. Thousands of miners die from mining accidents each year, especially from underground mining (hard rock), underground coal mining, although accidents also occur in Underground mining (hard rock), hard rock mining. Coal mining is considered much more hazardous than hard rock mining due to flat-lying rock strata, generally incompetent rock, the presence of methane gas, and coal dust. Most of the deaths these days occur in developing countries, and rural parts of developed countries where safety measures are not practiced as fully. A mining disaster is an incident where there are five or more fatalities. Causes Mining accidents can occur from a variety of causes, including leaks of poisonous gases such as hydrogen sulfide or explosive natural gases, especially firedamp or methane, dust explosions, collapsing of mine Stoping (mining method), stopes, mining-induced seismicity, flooding, or ...

Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.

Electrical Equipment
Electrical devices or electric devices are devices that functionally rely on electric energy ( AC or DC) to operate their core parts (electric motors, transformers, lighting, rechargeable batteries, control electronics). They can be contrasted with traditional mechanical devices which depend on different power sources like fuels or human physical strength. Electronic devices are a specialized kind of electrical devices in which electric power is predominantly used for data processing rather than the generation of mechanical forces. To better differentiate between both classes, electric devices that emphasize physical work are also called electromechanical. Mechatronics accentuates the intersection of both fields. Together, electronic and electric devices, their development, maintenance, and power supply comprise the subject of electrical engineering Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, dev ...

Felling Mine Disasters
The Felling Colliery (also known as Brandling Main) in Britain, suffered four disasters in the 19th century, in 1812, 1813, 1821 and 1847. By far the worst of the four was the 1812 disaster which claimed 92 lives on 25 May 1812. The loss of life in the 1812 disaster was one of the motivators for the development of miners' safety lamps such as the Geordie lamp and the Davy lamp. Colliery description Felling is an area in the English county of Tyne and Wear. Mining of the upper seams had continued throughout the 18th century. Following borings starting in 1758, the main pit was opened in 1779. The first seam to be worked was the High Main which ceased production in 1811. Shortly before the High Main was exhausted, the pit was deepened to reach the Low Main which came into production in May 1811, just a year before the disaster. The Low Main lies below the surface and is thick. Subsequently two other seams, the Bensham (or Maudlin) and the Hutton were won. To ensure adequate ...

Senghenydd Pit Disaster 1
Senghenydd (, ) is a former mining village in the community of Aber Valley in South Wales, approximately four miles northwest of the town of Caerphilly. Historically within the county of Glamorgan, it is now situated in the county borough of Caerphilly. In the United Kingdom Census 2001, the population of the Aber Valley (which also includes the neighbouring village of Abertridwr) was 6,696. The wind farm proposed in 2023 would see the village surrounded by turbines up to 200 metres high. Toponym The name derives originally from the name Sangan + suffix ydd, probably meaning "the land or territory associated with Sangan". The suffix 'ydd' is often used in Welsh, following a personal name, to denote ownership, as in ' Meirionnydd' or ' Eifionydd'.

Carbon Monoxide Poisoning
Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. Symptoms are often described as " flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. Large exposures can result in loss of consciousness, arrhythmias, seizures, or death. The classically described "cherry red skin" rarely occurs. Long-term complications may include chronic fatigue, trouble with memory, and movement problems. CO is a colorless and odorless gas which is initially non-irritating. It is produced during incomplete burning of organic matter. This can occur from motor vehicles, heaters, or cooking equipment that run on carbon-based fuels. Carbon monoxide primarily causes adverse effects by combining with hemoglobin to form carboxyhemoglobin (symbol COHb or HbCO) preventing the blood from carrying oxygen and expelling carbon dioxide as carbaminohemoglobin. Additionally, many other hemoproteins such as myoglob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manchukuo
Manchukuo, officially known as the State of Manchuria prior to 1934 and the Empire of Great Manchuria thereafter, was a puppet state of the Empire of Japan in Northeast China that existed from 1932 until its dissolution in 1945. It was ostensibly founded as a republic, its territory consisting of the lands seized in the Japanese invasion of Manchuria; it was later declared to be a constitutional monarchy in 1934, though very little changed in the actual functioning of government. Manchukuo received limited diplomatic recognition, mostly from states aligned with the Axis powers, with its existence widely seen as illegitimate. The region now known as Manchuria had historically been the homeland of the Manchu people, though by the 20th century they had long since become a minority in the region, with Han Chinese constituting by far the largest ethnic group. The Manchu-led Qing dynasty, which had governed China since 17th century, was overthrown with the permanent abolition of the ...

Puppet State
A puppet state, puppet régime, puppet government or dummy government is a State (polity), state that is ''de jure'' independent but ''de facto'' completely dependent upon an outside Power (international relations), power and subject to its orders.Compare: Puppet states have nominal Sovereign state, sovereignty, except that a foreign power effectively exercises control through economic or military support. By leaving a local government in existence the outside power evades all responsibility, while at the same time successfully paralysing the local government they tolerate. Puppet states differ from Alliance, allies, who choose their actions of their own initiative or in accordance with Treaty, treaties they have voluntarily entered. Puppet states are forced into Rubber stamp (politics), legally endorsing actions already taken by a foreign power. Characteristics Puppet states are "endowed with the outward symbols of authority", such as a name, National flag, flag, anthem, cons ...

Coal Dust Explosion
Coal dust is a fine- powdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal easier to handle. However, coal dust is hazardous to workers if it is suspended in air outside the controlled environment of grinding and combustion equipment. It poses the acute hazard of forming an explosive mixture in air and the chronic hazard of causing pulmonary illness in people who inhale excessive quantities of it. The distribution of the particle-size of coal dust is frequently measured in mesh. The British slang term for cheap fuel consisting of coal dust (slack) containing small lumps of coal (nuts) is nutty slack. Energy generation For use in thermal power plants, coal is ground into dust using a devic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
