Mine Rescue
Mine rescue or mines rescue is the specialised job of rescuing miners and others who have become trapped or injured in underground mines because of mining accidents, roof falls or floods and disasters such as explosions. Background Mining laws in developed countries require trained, equipped mine rescue personnel to be available at all mining operations at surface and underground mining operations. Mine rescue teams must know the procedures used to rescue miners trapped by various hazards, including fire, explosions, cave-ins, toxic gas, smoke inhalation, and water entering the mine. Most mine rescue teams are composed of miners who know the mine and are familiar with the mining machinery they may encounter during the rescue, the layout of workings and geological conditions and working practices. Local and state governments may have teams on-call ready to respond to mine accidents. Rescuers and equipment The first mines rescuers were the colliery managers and volunteer c ...

Interactive Mine Rescue Setting (8869207692)
Across the many fields concerned with interactivity, including information science, computer science, human-computer interaction, communication, and industrial design, there is little agreement over the meaning of the term "interactivity", but most definitions are related to interaction between users and computers and other machines through a user interface. Interactivity can however also refer to interaction between people. It nevertheless usually refers to interaction between people and computers – and sometimes to interaction between computers – through software, hardware, and networks. Multiple views on interactivity exist. In the "contingency view" of interactivity, there are three levels: #Not interactive, when a message is not related to previous messages. #Reactive, when a message is related only to one immediately previous message. #Interactive, when a message is related to a number of previous messages and to the relationship between them.

Henry Fleuss
Henry Albert Fleuss (13 June 1851 – 6 January 1933) was a pioneering diving engineer, and Master Diver for Siebe, Gorman & Co. of London. Fleuss was born in Marlborough, Wiltshire in 1851. In 1878 he was granted a patent which improved rebreathers. His apparatus consisted of a rubber mask connected to a breathing bag, with (estimated) 50-60% O2 supplied from a copper tank and CO2 scrubbed by rope yarn soaked in a solution of caustic potash, the system giving a duration of about three hours. Fleuss tested his device in 1879 by spending an hour submerged in a water tank, then one week later by diving to a depth of 5.5m in open water, upon which occasion he was slightly injured when his assistants abruptly pulled him to the surface. Fleuss's apparatus was first used under operational conditions in November 1880 by Alexander Lambert, lead diver of the Severn Tunnel construction project. Trained by Fleuss, he was able to close a submerged sluice door in the tunnel which had def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chokedamp
Blackdamp (also known as stythe or choke damp), sometimes found in enclosed environments such as mines, sewers, wells, tunnels and ships' holds, is an asphyxiant, reducing the available oxygen content of air to a level incapable of sustaining human or animal life. It is not a single gas but a mixture of unbreathable gases left after oxygen is removed from the air; it typically consists of nitrogen, carbon dioxide and water vapour. The term is etymologically and practically related to terms for other underground mine gases such as fire damp, white damp, stink damp, and afterdamp. Etymology The meaning of "damp" in this term, while nowadays understood to imply humidity, presents evidence of having been separated from this meaning at least by the first decade of the 18th century; the original meaning of "vapor" derives from a Proto-Germanic origin, ''dampaz'', which gave rise to its immediate English predecessor, the Middle Low German ''damp'' (with no record of an Old English inte ...

Firedamp
Firedamp is any flammable gas found in coal mines, typically coalbed methane. It is particularly found in areas where the coal is bituminous. The gas accumulates in pockets in the coal and adjacent strata and, when they are penetrated, the release of the gas can cause explosions. Historically, if such a pocket was highly pressurized, it was termed a "bag of foulness". Name Damp is the collective name given to all gases (other than air) found in coal mines in Great Britain and North America. As well as firedamp, other damps include '' blackdamp'' (nonbreathable mixture of carbon dioxide, water vapour and other gases); whitedamp (carbon monoxide and other gases produced by combustion); poisonous, explosive '' stinkdamp'' (hydrogen sulfide), with its characteristic rotten-egg odour; and the insidiously lethal '' afterdamp'' (carbon monoxide and other gases) which are produced following explosions of firedamp or coal dust. Etymology Often hyphenated as fire-damp, this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Aid
First aid is the first and immediate assistance given to any person with a medical emergency, with care provided to preserve life, prevent the condition from worsening, or to promote recovery until medical services arrive. First aid is generally performed by someone with basic medical or first response training. Mental health first aid is an extension of the concept of first aid to cover mental health, while psychological first aid is used as early treatment of people who are at risk for developing Post-traumatic stress disorder, PTSD. Conflict first aid, focused on preservation and recovery of an individual's social or relationship well-being, is being piloted in Canada. There are many situations that may require first aid, and many countries have legislation, regulation, or guidance, which specifies a minimum level of first aid provision in certain circumstances. This can include specific training or equipment to be available in the workplace (such as an Automated External ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pretoria Pit Disaster
The Pretoria Pit disaster was a mining accident on 21 December 1910, when an underground explosion occurred at the Hulton Colliery Bank Pit No. 3, known as the Pretoria Pit, in Over Hulton, Westhoughton, then in the historic county of Lancashire, in North West England. A total of 344 men and boys lost their lives. Background There were approximately 2,400 workers employed by the Hulton Colliery Company in 1910. On the morning of 21 December, approximately 900 workers arrived for the day shift. They were working five coal seams of the Manchester Coalfield: the Trencherbone, Plodder, Yard, Three-Quarters and Arley mines. Explosion At 7:50am, there was an explosion in the Plodder Mine, which was thought to have been caused by an accumulation of gas from a roof collapse the previous day. That day 345 workers descended the No 3 bank pit shaft to work in the Plodder, Yard and Three Quarters mines. Of those, only four survived to be brought to the surface. One died immed ...

Abram, Greater Manchester
Abram is a village and electoral ward in the Metropolitan Borough of Wigan, Greater Manchester, England. It lies on flat land on the northeast bank of the Leeds and Liverpool Canal, west of Leigh, southeast of Wigan, and west of Manchester. Abram is a dormitory village with a population of 9,855. Historically part of Lancashire, Abram anciently formed a township and chapelry in the parish of Wigan and hundred of West Derby. Abram appears in an entry of an ancient survey of Lancashire in 1212 under the name "Edburgham". The urbanisation and development of Abram largely coincided with the Industrial Revolution. Abram is at the centre of a coal district, and industrial scale coal mining was introduced to Abram around the middle of the 19th century with the opening of several collieries. In 1911, Abram was described as "distinctly unpicturesque ... trees are in the minority, and stunted and blackened with smoke", with "collieries, pit-banks, and railway lines" as well ...

Maypole Colliery
A maypole is a tall wooden pole erected as a part of various European folk festivals, around which a maypole dance often takes place. The festivals may occur on 1 May or Pentecost (Whitsun), although in some countries it is instead erected during Midsummer (20–26 June). In some cases, the maypole is a permanent feature that is only utilized during the festival, although in other cases it is erected specifically for the purpose before being taken down again. Primarily found within the nations of Germanic Europe and the neighboring areas which they have influenced, its origins remain unknown. It has often been speculated that the maypole originally had some importance in the Germanic paganism of Iron Age and early Medieval cultures and that the tradition survived Christianisation, albeit losing any original meaning that it had. It has been a recorded practice in many parts of Europe throughout the Medieval and Early Modern periods, although it became less popular in the 18th a ...

1 & 2 Geo
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Mines Act 1911
The Coal Mines Act 1911 ( 1 & 2 Geo. 5. c. 50) amended and consolidated legislation in the United Kingdom related to collieries. A series of mine disasters in the 19th and early-20th centuries had led to commissions of enquiry and legislation to improve mining safety. The 1911 Act, sponsored by Winston Churchill, was passed by the Liberal government of H. H. Asquith. It built on earlier regulations and provided for many improvement to safety and other aspects of the coal mining industry. An important aspect was that mine owners were required to ensure there were mines rescue stations near each colliery with equipped and trained staff. Although amended several times, it was the main legislation governing coal mining for many years. Background In the United Kingdom a series of disasters in the 19th century brought about royal commissions which developed the idea of improving mine safety. In 1906 a major explosion at a colliery in Courrières, northern France, caused the deaths ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howe Bridge Mines Rescue Station
Howe Bridge Mines Rescue Station was the first Mine rescue, mines rescue station on the Lancashire Coalfield opened in 1908 in Howe Bridge, Atherton, Greater Manchester, Atherton, then in the Historic counties of England, historic county of Lancashire, England. Before Britain's first mines rescue station opened at Tankersley, South Yorkshire, Tankersley in Yorkshire in 1902, pit managers and volunteers were usually the first untrained mines rescuers. They fought fires, rescued victims and recovered bodies in the collieries in which they worked. Rescue stations were recommended in a Royal Commission in 1886 but were not compulsory until after the 1911 Coal Mines Act was passed. In 1906 the Lancashire and Cheshire Coal Owners Association formed a committee which decided to provide a mines rescue station in Lovers Lane Atherton. The first rescuers were provided with Siebe Gorman Proto breathing apparatus which was selected by competition. A team from the rescue station was tasked wit ...

Rebreather
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantial unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, while also eliminating the bubbles otherwise produced by an open circuit system. The latter advantage over other systems is useful for covert military operations by frogmen, as well as for undisturbed observation of underwater wildlife. A rebreather is generally understood to be a portable apparatus carried by the user. The same technology on a vehicle or non-mobile installation is more likely to be referred to as a life-support system. Rebreather technology may be used where breathing gas supp ...
