The Davy lamp is a safety lamp used in flammable atmospheres, invented in 1815 by Sir Humphry Davy. It consists of a wick lamp with the flame enclosed inside a mesh screen. It was created for use in coal mines, to reduce the danger of explosions due to the presence of methane and other flammable gases, called firedamp or minedamp.
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 can trigger explosions. Historically, if such a pocket was highly pressurized, it was termed a "bag of foulness".
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 coal mining, although accidents also occur in 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.
Trimdon Grange is a village in County Durham, in England. It is situated ten miles to the west of Hartlepool, and a short distance to the north of Trimdon.
A carbide lamp or acetylene gas lamp is a simple lamp that produces and burns acetylene (C2H2), which is created by the reaction of calcium carbide (CaC2) with water (H2O).
A safety lamp is any of several types of lamp that provides illumination in places such as coal mines where the air may carry coal dust or a build-up of flammable gases, which may explode if ignited, possibly by an electric spark. Until the development of effective electric lamps in the early 1900s, miners used flame lamps to provide illumination. Open flame lamps could ignite flammable gases which collected in mines, causing explosions; safety lamps were developed to enclose the flame to prevent it from igniting the explosive gases. Flame safety lamps have been replaced for lighting in mining with sealed explosion-proof electric lights, but continue to be used to detect gases.
On December 8, 1981, 13 coal miners lost their lives as the result of an explosion at the No. 21 Mine, an underground coal mine near Whitwell, Tennessee.
The Courrières mine disaster, Europe's worst mining accident, caused the death of 1,099 miners in Northern France on 10 March 1906. This disaster was surpassed only by the Benxihu Colliery accident in China on 26 April 1942, which killed 1,549 miners. A coaldust explosion, the cause of which is not known with certainty, devastated a coal mine operated by the Compagnie des mines de houille de Courrières. Victims lived nearby in the villages of Méricourt, Sallaumines, Billy-Montigny, and Noyelles-sous-Lens. The mine was 2 km (1 mi) to the east of Lens, in the Pas-de-Calais département.
The Ulyanovskaya Mine disaster was caused by a methane explosion that occurred on March 19, 2007 in the Ulyanovskaya longwall coal mine in the Kemerovo Oblast. At least 108 people were reported to have been killed by the blast, which occurred at a depth of about 270 meters (885 feet) at 10:19 local time. The mine disaster was Russia's deadliest in more than a decade.
The Yubileinaya mine is a coal mine in the Kemerovo Oblast area of Siberia, Russia. The mine is operated by Joint-Stock Company "TopProm", owned by the Limited Liability Company "AVD-Capital"
The 2007 Zasyadko mine disaster was a mining accident that happened on November 18, 2007 at the Zasyadko coal mine in the eastern Ukrainian city of Donetsk.
The Cross Mountain Mine disaster was a coal mine explosion that occurred on December 9, 1911, near the community of Briceville, Tennessee, in the southeastern United States. In spite of a well-organized rescue effort led by the newly created Bureau of Mines, 84 miners died in the disaster. The cause of the explosion was the ignition of dust and methane gas released by a roof fall. Miners would use open oil lamps to provide a light source down in the mines.
The 2009 Wujek-Śląsk mine blast occurred at the Wujek bituminous coal mine in Ruda Śląska, Poland on 18 September 2009. At least 20 miners were killed and at least 37 more were hospitalised. It is the country's deadliest mining accident since the deaths of 23 miners from methane at the Silesia's Halemba mine in November 2006.
The Upper Big Branch Mine disaster occurred on April 5, 2010, roughly 1,000 feet (300 m) underground in Raleigh County, West Virginia at Massey Energy's Upper Big Branch coal mine located in Montcoal. 29 out of 31 at the site were killed. The coal dust explosion occurred at 3:27 pm. The incident was the worst in the United States since 1970, when 38 miners were killed at Finley Coal Company's No. 15 and 16 mines in Hyden, Kentucky. A state funded independent investigation later found Massey Energy directly responsible for the blast.
The Raspadskaya mine explosion was a mine explosion in the Raspadskaya mine, located near Mezhdurechensk in Kemerovo Oblast, Russia, which occurred on 8 May 2010. It was believed to have been caused by a buildup of methane. The initial explosion was followed by a second approximately four hours later which collapsed the mine's ventilation shaft and trapped several rescue workers. By 18 May 2010, 66 people were confirmed to have died with at least 99 others injured and as many as a further 24 unaccounted for.
In February 2016, a series of explosions caused the deaths of 36 people, including 31 miners and five rescue workers, at the Severnaya coal mine 10 kilometres north of the city of Vorkuta, Komi Republic, Russia. The explosions were believed to be caused by ignition of leaking methane gas. It is the second deadliest mining disaster of the 2010s behind the Soma mine disaster, and fourth deadliest of the 21st century thus far.
A methane explosion occurred at the Hlobane Colliery, Natal, South Africa on 12 September 1983, killing 68 miners. The disaster occurred on the 39th anniversary of a similar explosion in 1944 where 57 miners were killed at the same mine.
The Listvyazhnaya mine disaster was a mining accident that occurred on 25 November 2021 in a coal mine in Kemerovo Oblast, Russia. Smoke from a fire in a ventilation shaft caused the suffocation of over 40 miners. A failed attempt to rescue the trapped miners resulted in the deaths of at least five rescuers when the mine exploded. It is the deadliest mine accident in Russia since the 2010 Raspadskaya mine explosion in the same region.
At least 31 people are suspected to have died in a methane gas explosion at a disused gold mine in South Africa around the third week of May in 2023.
An underground methane explosion occurred at the Trans-Natal Colliery near Ermelo in South Africa on 9 April 1987, killing 35 miners.
