Coal mining was a very dangerous job.

A great step forward in countering the problem of firedamp came when safety lamps, intended to provide illumination whilst being incapable of igniting firedamp, were brought forward by both George Stephenson and Sir Humphry Davy, in response to accidents such as the Felling mine disaster near Newcastle upon Tyne which killed 92 people on 25 May 1812.

All rights reserved. The Revd Dr Robert Gray of Bishopwearmouth in Sunderland, founder of the Society for Preventing Accidents in Coalmines, had written to Davy suggesting that he might use his 'extensive stores of chemical knowledge' to address the issue of mining explosions caused by firedamp, or methane mixed with oxygen, which was often ignited by the open flames of the lamps then used by miners. From moonshoot to balconing: discover the latest words added to the Collins Dictionary. Damps is the collective name given to all gases (other than air) found in coal mines in Great Britain. Wood engraving. The time between the onset of initial symptoms and the start of frank asphyxiation (and rapid unconsciousness) can be as short as seconds. Blackdamp is encountered in enclosed environments such as mines, sewers, wells, tunnels and ships' holds. Item Information. Blackdamp is considered a particularly pernicious type of damp (especially in a historical context), due to its omnipresence where exposed coal is found, and slow onset of symptoms. It occurs with particular frequency in abandoned or poorly ventilated coal mines. A month before Davy presented his design to the Royal Society, Stephenson demonstrated his own lamp to two witnesses by taking it down Killingworth Colliery and holding it in front of a fissure from which firedamp was issuing.

It forms explosive... | Meaning, pronunciation, translations and examples Lying east of the Bala Fault, the mine was extremely dry, unlike mines to the west of the fault, and was therefore prone to firedamp. However, fire-damp is not only the threat. Despite rescuers' efforts, they could not be reached before they suffocated in the blackdamp atmosphere. Download our English Dictionary apps - available for both iOS and Android. Such accidents were usually initiated by firedamp ignitions, the shock wave of which raised coal dust from the floor of the mine galleries to make an explosive mixture. It caused many deaths in coal mines before the invention of the Geordie lamp and Davy lamp. Last 300 years. Thus, if the warning signs are missed, a large number of miners can be rapidly incapacitated in the same short period of time, leaving no one to summon help. by Penguin Random House LLC and HarperCollins Publishers Ltd.

Our new online dictionaries for schools provide a safe and appropriate environment for children. Mining accidents can happen 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 stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment).

two miles of timbers were blown out and flames shot all through the mine -- all survivors burned and not more than four will survive.

The Newcastle Courant thought the celebrations fully justified; because of the scale of the undertaking ('the Attempt being generous and great': a shaft twelve foot by ten had been sunk seventy-seven fathoms (the deepest a pit had been sunk in any part of Europe) to a three-yard thick coal seam (the Main Band) in twenty-three months, using thirty barrels of gunpowder, and without any loss of life or limb by the workforce); because of the difficulties overcome ( which "would have discourag'd all common Undertakers" (a "blower" of firedamp had been encountered at forty-two fathoms) but had been overcome by the 'unparallel'd Conduct and Skill of Sir James Lowther's Managers, Messieurs John and Carlisle Spedding'); but above all 'The perfecting of this costly Undertaking renders a universal Joy to the Inhabitants...; because the consequence is such as makes certain a valuable Colliery for many Generations'. Fire-damp mixed with air presents a highly explosive mixture. From 'Le Journal de la Jeunesse' (Paris 1885). View usage for: All Years Within the coal mining industry, this type of coal is known for releasing the largest amounts of firedamp, a dangerous mixture of gases that can cause underground explosions. Many of the initial symptoms of oxygen deprivation (dizziness, light-headedness, drowsiness and poor coordination) are relatively innocuous and can easily be mistaken for simple fatigue, given the physically strenuous job of coal mining. Condition:--not specified. The Bodies all Recovered.

Last 10 years Tynesiders may have been given this name, a local diminutive of the name "George", because their miners used George Stephenson's safety lamp (invented in 1815 and called a "Georgie lamp") to prevent firedamp explosions, rather than the Davy lamp used elsewhere. Afterdamp is the toxic mixture of gases left in a mine following an explosion caused by firedamp, which itself can initiate a much larger explosion of coal dust.

It produces no obvious odor (unlike the hydrogen sulfide of stinkdamp), is constantly being reintroduced to the air (instead of being released in pockets from actively mined sections), and does not require combustion in order to be released (unlike whitedamp or afterdamp).
It occurs with particular frequency in abandoned or poorly ventilated coal mines. of the twenty-one men entombed but nine escaped.

This was the miner who, swathed in damp sacking, undertook the task of igniting pockets of which, the inflammable gas Methane, called Fire-damp which, if allowed to build up, could cause disastrous explosions in coal mines. Firedamp explosions can trigger the much-more-dangerous coal dust explosions, which can engulf an entire pit. There are some words that seem to be of perennial interest, so if you compare the list of words that were looked up most often in March with the words that were looked up most often in September, you will find a lot of words appearing on both lists.
