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 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.

For broader coverage of this topic, see List of accidents and disasters by death toll.

Causes

Mining accidents can occur from a variety of causes, including leaks of poisonous gases such as hydrogen sulfide[1] or explosive natural gases, especially firedamp or methane,[2] 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). Use of improper explosives underground can also cause methane and coal dust explosions.

Worst mining disaster in history

On April 26, 1942, during World War II, in the Benxihu (Honkeiko) coal mine in Liaoning Province, China, what is believed to be the worst mining disaster in history took the lives of over 1,500 people.[3]

The disaster occurred in an area that is now within the borders of modern-day China, but was at the time part of the puppet state of Manchukuo established by Japan after it invaded and occupied northeast China in the 1930s. The Japanese administrators of the mine forced Chinese labourers to conduct the mining work under harsh conditions. The disaster began with a fire in the mine. In order to suppress it, the Japanese operators cut off air in the ventilation shafts and blocked off the mine so as to deprive the blaze of oxygen. Most workers were not evacuated before these actions, and they were trapped within the sealed-off area of the mine; they suffocated to death as the fire burned off oxygen and produced carbon monoxide poisoning. Once the fire died out and the mine was re-opened, ten days were required for workers to remove debris and reach the bodies of those who had been trapped inside the mine.[4] The dead consisted of 1,518 Chinese and 31 Japanese. Most of the bodies were later buried in a mass grave. After the war and liberation of China by the Soviet Union, the disaster was investigated. The Soviet report concluded that the majority of the deaths were not caused directly by the initial fire but were the result of carbon monoxide poisoning and suffocation resulting from decisions of the Japanese.[5]

This is an incomplete list of notable mining accidents and disasters:

19th century

20th century
  • 19 May 1902: 216 miners were killed in the Fraterville Mine disaster in Fraterville, Tennessee
  • 25 January 1904: 179 miners and two aid workers were killed in the Harwick mine disaster, Cheswick, Pennsylvania
  • 28 April 1904: 63 people were killed in Villanueva del Río, Sevilla; it was the worst mining accident recorded in Spain.[13]
  • 20 February 1905 Virginia City Mine explosion (Alabama), 112 killed.[14]
  • March 10, 1906: Courrières mine disaster in Courrières, France. 1,099 workers died in the worst mine accident in European history.
  • December 1, 1907: Naomi Mine Explosion in Fayette City, Pennsylvania. 34 workers died.
  • December 6, 1907: Monongah Mining disaster in Monongah, West Virginia. Official death toll is 362, but due to inadequate record keeping, the true death toll could be around 500.[15] Victims were mostly Italian immigrant workers, including children. Considered the worst coal mining accident in American history.
  • 16 December 1907: Yolande mine explosion near Birmingham, Alabama. Fifty-seven killed.[16]
  • December 19, 1907: Darr Mine disaster in Rostraver Township, Pennsylvania. 239 workers died, including children.
  • August 18, 1908: Maypole Colliery disaster in Abram, Greater Manchester, England. 75 men and boys died.[17]
  • November 13, 1909: Cherry Mine disaster in Cherry, Illinois. 259 workers, some as young as eleven, died in this mine fire, which had the most fatalities of any mine fire in the United States.
  • December 21, 1910: The Pretoria Pit disaster in Westhoughton, Lancashire, 344 men and boys lost their lives in this explosion, which is the worst mining disaster on one day in England.
  • April 8. 1911 Banner Mine disaster near Littleton, Alabama. Of the 128 men killed, most were leased Black convicts.
  • 9 December 1911: Cross Mountain Mine disaster killed 84 miners in Briceville, Tennessee
  • October 14, 1913: Senghenydd Colliery disaster, the worst mining accident in the United Kingdom; 439 workers died in Wales.
  • October 22, 1913: Dawson Stag Canon Number 2 Mine disaster, near Dawson, New Mexico,[18] where 263 workers were killed due to illegal use of dynamite.
  • June 8, 1917: Speculator Mine disaster in Butte, Montana. An electric cable being lowered into the mine was accidentally ignited at 2,500 meters below the surface. The fire quickly climbed the cable and ignited the mine's wooden shaft. The shaft became a chimney, eliminating the mine's primary source of oxygen. Nearly all of the 168 fatalities were due to asphyxia, from carbon monoxide poisoning. This is the deadliest underground hard rock mining disaster in United States history.
  • January 12, 1918 The Minnie Pit disaster in Staffordshire, United Kingdom was a coal mining accident in which 155 men and boys died (144 from carbon monoxide poisoning and 11 from violence, plus carbon monoxide poisoning). The disaster, which was caused by an explosion due to firedamp, is the worst ever recorded in the North Staffordshire Coalfield. An official investigation never established what caused the ignition of flammable gases in the pit.
  • February 8, 1923 The Dawson Stag Canon #1 Mine Explosion killed 123; many were descendants of men killed in the 1913 explosion at the same mine. As a mine car derailed, it caused sparks and ignited coal dust, causing the explosion.
  • 1927–1932: Hawks Nest Tunnel Disaster, near Gauley Bridge, West Virginia, United States. Over several years, 476 workers died from silicosis.
  • July 2, 1937 The Holditch (also known as Brymbo) Colliery disaster was a coal mining accident in Chesterton, Staffordshire, England, in which 30 men died and eight were injured. It was caused due to a fire and subsequent explosions. Fatalities were exacerbated because management chose to try to save the coal seam, and risked the lives of mine workers while delaying evacuation.
  • May 10, 1938: Explosion in Markham No. 1 Colliery near Staveley, Derbyshire, England. 79 workers died and 40 were seriously injured.[19]
  • April 26, 1942: Benxihu Colliery disaster in Benxi, Liaoning, China. 1,549 workers died, in the worst coal mine accident ever in the world. At the time, during World War II, this area was occupied by Japan and the mine was under control of Japanese managers. The overwhelming number of dead were Chinese forced labourers.
  • February 20, 1946: Monopol Grimberg III/IV disaster in Bergkamen, Ruhr Coalfield, Germany. 405 died.
  • December 21, 1951: Orient 2 coal mine explosion in West Frankfort, Illinois. 119 workers died.
  • December 10, 1954: Newton Chikli Colliery disaster, Chhindwara (M.P.), India. Flooding of the mine was caused by inrush of water from old workings of the same mine. There were 112 persons inside the mine when it was flooded. 49 persons managed to escape through the incline; the remaining 63 persons were trapped and drowned.
  • August 8, 1956: Bois du Cazier disaster in Marcinelle, Belgium. A fire in the mines resulted in 262 deaths; of the 274 people working in Bois du Cazier on that morning, only twelve survived. 138 of the victims were Italian migrant workers.
  • Jan 22, 1959: Knox Mine disaster at River Slope Mine, Port Griffith Luzerne County, Pennsylvania - flooding from the riverbed above works killed 12 miners
  • October 28, 1958 Oglebay-Norton mine, Craigsville, West Virginia 14 died.

  • 9 May 1960: Laobaidong colliery coal dust explosion Datong, China, 682 died.
  • 7 July 1961: Dukla Coal Mine, Dolní Suchá, Czechoslovakia, Fire and carbon monoxide poisoning caused the deaths of 108 miners.
  • 9 November 1963: Mitsui Miike Coal Mine disaster Mitsui Miike, Ōmuta, Fukuoka, Japan; 458 died.[20]
  • May 28, 1965: Dhanbad coal mine disaster took place in Jharkhand, India, killing over 300 miners.
  • May 17, 1965: Cambrian Colliery in South Wales; 31 died.
  • October 21, 1966: Aberfan disaster was a catastrophic collapse of a colliery spoil-tip that caused an avalanche in the Welsh village of Aberfan, killing 116 children and 28 adults.
  • November 20, 1968: Farmington Mine Disaster in Farmington, West Virginia. 78 workers died. As a result of the disaster, the U.S. Congress passed the Federal Coal Mine Health and Safety Act of 1969.
  • 1972: Wankie coal mine disaster Wankie, Rhodesia/Zimbabwe, 426 fatalities.
  • 21 March 1973: Lofthouse Colliery disaster, West Yorkshire, England, seven fatalities.
  • July 30, 1973: Markham Colliery disaster near Staveley, Derbyshire, England. 18 workers were killed and 11 seriously injured when a descending cage failed to slow at the bottom of the mine shaft.
  • 27 December 1975: Chasnala mining disaster, Dhanbad, Jharkhand, India, 372 miners died and another 130 contract workers are claimed to have died when water from adjacent mine gusted after the wall in between collapsed.
  • 8 December 1981: No. 21 Mine explosion near Whitwell, Tennessee. 13 coal miners died as a result of the explosion.[21]
  • July 19, 1985: Val di Stava dam collapse took place in the village of Stava, near Tesero, Italy, when two tailings dams failed that had been used for sedimenting the mud from the nearby Prestavel mine. It resulted in one of Italy's worst disasters, killing 268 people, destroying 63 buildings, and demolishing eight bridges.

  • August 28, 1994: Rajpura Dariba Mine VRM disaster, Dariba, Udaipur, India: This incident occurred due to flooding of the slurry from a mined VRM Underground mining (hard rock)#Mining methods stop, where cemented fill could not settle and its plug failed. This slurry accumulated in the plugged shaft, which could not take the load and subsequently failed. All of the material fell in the shaft, resulting in the drowning deaths of 63 people working below.[22][23]
  • 10 May 1995 Vaal Reefs, South Africa; a locomotive fell down a lift shaft and landed on a cage, causing the deaths of 104 people.

21st century
  • January 30, 2000: Baia Mare cyanide spill took place in Baia Mare, Romania. The accident, called the worst environmental disaster in Europe since Chernobyl, was a release of 100,000 tons of cyanide-contaminated water by an Aurul mining company when a reservoir broke, releasing its waters into the rivers Someş, Tisza and Danube. Although no human fatalities were reported, the leak killed up to 80% of aquatic life of some of the affected rivers.
  • February 19, 2006: Pasta de Conchos accident. 65 miners lost their lives in the mining accident near Nueva Rosita, Coahuila, Mexico. Only 2 bodies have been recovered.
  • April 5, 2010: Upper Big Branch Mine disaster, West Virginia. An explosion occurred in Massey Energy's Upper Big Branch coal. 29 of 31 miners at the site were killed.[24]
  • August 5, 2010: 2010 Copiapó mining accident, Atacama Desert, Chile. The 121-year-old San José copper–gold mine structurally collapsed at 14:05 CLT. The heart of the mountain, which had the mass of two Empire State Buildings, collapsed and caused catastrophic damage to the mine. It blocked all possible escape routes for the 33 miners trapped at 2300 feet. After 69 days, all 33 miners were rescued.
  • November 19, 2010: Pike River Mine disaster in New Zealand. At 3:45pm, the coal mine exploded. 29 men underground died immediately, or shortly afterwards, from the blast or from the toxic atmosphere. Two men in the stone drift, some distance from the mine workings, managed to escape. (Extract from Royal Commission of Enquiry Report on Pike River.)
  • May 13, 2014: Soma mine disaster took place in Soma, Turkey. The accident was reportedly the worst mining accident ever in Turkey, and is the worst mining accident so far in the 21st century so far. 301 people died.
  • January 6, 2019: 2019 Kohistan mine collapse, Afghanistan. The accident killed at least 30 gold miners.[25]
  • July 2, 2020: At least 113 people were killed in a landslide in the 2020 Hpakant jade mine disaster in the Hpakant area in Myanmar.[26]

Breaking the News, painted by Australian artist John Longstaff in 1887, depicts a miner informing a widow of her husband's death in a mining accident.
Mount Mulligan disaster 1921-the steel cable drums were blown 50 feet from their foundations.

The Bulli Mine Disaster of 23 March 1887 involved a gas explosion in the mine that killed 81 men and boys, leaving 50 women widows and 150 children without fathers.

The Mount Kembla Mine Disaster of 31 July 1902 was an explosion resulting in the death of 96 miners, including two engaged in rescue work. It remains the worst mining disaster in Australian history.

A coal dust explosion at the Mount Mulligan mine on 19 September 1921 killed 75 or 76 workers.

Tasmania's Beaconsfield Mine collapse occurred on 25 April 2006. Of the 17 people who were in the mine at the time, 14 escaped immediately following the collapse, one was killed and the remaining two were found alive after five days. The survivors were trapped in a 1.5m x 1.2m cherry picker cage, which had saved them from being crushed by rocks.[27] As it was not safe for rescuers to blast their way through, a special borer was brought in to drill an escape shaft. They were finally released on 9 May after 14 days underground.

Three mining disasters occurred at Moura in a 20-year period. The first of these was in 1975, at the Kianga Mine, where 13 men died in an underground explosion. The mine was sealed without their bodies being retrieved. In 1986 a second disaster occurred, as an underground explosion, which took the lives of 12 miners.[28] The bodies of all those persons were retrieved. In Moura on 7 August 1994 a third major mining accident occurred with an explosion at Moura No. 2 Mine. A second explosion at the mine approximately a day and a half later saw rescue attempts abandoned, and the mine was sealed, with the bodies of the 11 miners unretrieved.[29]

In the 1996 Gretley coal mine disaster, near Newcastle, four men were killed when their mining machine broke into the flooded workings of an old coalmine, abandoned over 80 years earlier.[30][31]

Four miners were killed in a windblast incident at the Northparkes mine outside the New South Wales town of Parkes in 1999.[32]

Belgium

On March 4, 1887, 120 miners died in a coal mine in La Boule, Borinage due to a methane explosion.[33]

On the morning of August 8, 1956, a fire in the mine Bois du Cazier in Marcinelle caused 262 victims, with only 12 survivors.[34] A mining cart on an elevator cage hit an oil pipe and electricity lines, with the resulting fire trapping the miners. Most of the victims were immigrants (136 Italians, 8 Poles, 6 Greeks, 5 Germans, 5 Frenchmen, 3 Hungarians, 1 Englishman, 1 Dutchman, 1 Russian and 1 Ukrainian.[35])

Bosnia and Herzegovina

On September 4, 2014, after a 3.5 Richter earthquake hit Zenica caused rock burst in coal mine "Raspotočje", 34 miners remained trapped inside the mine. It was later reported that 5 miners were killed in the accident.[36]

Canada
  • On 18 September 1992, at the height of a labour dispute at the Giant Mine, an explosion resulting from a bomb planted by a striking worker, killed nine men riding through a transport tunnel.
  • Coal mining accidents in the province of Nova Scotia spanning 65 years referred to collectively as the Springhill mining disasters, which claimed in total at least 138 lives of men and boys due to coal dust explosions. The Westray Mine disaster in 1992 claimed the lives of 26 miners in a methane/coal dust explosion at a recently opened mining operation. Both of these mines were subsequently permanently closed in the wake of these events.
  • The 1887 Nanaimo mine explosion in Nanaimo, British Columbia killed 150 miners at the No 1 Esplanade Mine. Explosives were laid improperly triggering a massive mine-wide explosion. Most miners were killed instantly, only 7 survived. Of the 150 workers killed, 53 of them were Chinese, the names of which are mostly unknown.
  • The Hillcrest mine disaster, the worst coal mining disaster of Canadian history, occurred in Alberta in 1914. Deaths from the methane and coal dust-fueled explosion numbered 189; news coverage was eclipsed by the First World War. The mine remained in use until 1939.

Central African Republic

In June 2013, heavy rains provoked the collapse of a gold mine in Ndassima, killing 37 miners and injuring many others.[37]

Chile

In June 1945, during a fire, 355 workers died in El Teniente by inhaling carbon monoxide, in what was called the "Tragedia del Humo" (English: The Smoke Tragedy).

In January 2006, an explosion occurred in a mine in Copiapó, leaving 70 miners trapped underground. The miners were rescued after a brief period of time, but two people died.

In August 2010, 33 miners were trapped underground in Copiapó. After two weeks communication was made with them but it was said at least four more months would pass before they could be rescued, though essential services could still be provided. The rescues began on October 12, 2010 and all the 33 miners were rescued within 22 hours of first rescue. The world watched and cheered.[38]

China
Main article: List of coal mining accidents in China

According to one source, in 2003 China accounted for the largest number of coal-mining fatalities, accounting for about 80% of the world's total, although it produced only 35% of the world's coal.[39] Between January 2001 and October 2004, there were 188 accidents that had a death toll of more than 10, about one such accident every 7.4 days.[39] After the 2005 Sunjiawan mine disaster, which killed at least 210 miners, a meeting of the State Council was convened to work on measures to improve work safety in coal mines. The meeting's statement indicated serious problems such as violation of safety standards and overproduction in some coal mines. Three billion yuan (360 million US dollars) were dedicated for technological renovation on work safety, gas management in particular, at state-owned major coal mines. The government also promised to send safety supervision teams to 45 coal mines with serious gas problems and invite colliery safety experts to evaluate safety situations in coal mines and formulate prevention measures.[40]

In 2006, according to the State Work Safety Supervision Administration, 4,749 Chinese coal miners were killed in thousands of blasts, floods, and other accidents. For example, a gas explosion at the Nanshan Colliery killed 24 people on November 13, 2006; the mine was operating without any safety license and the Xinhua News Agency claimed the cause was incorrect usage of explosives. However, the 2006 rate was 20.1% less than 2005 despite an 8.1% increase in production.[41]

The New York Times reported that China's lack of a free press, independent trade unions, citizen watchdog groups and other checks of official power has made cover-ups of mining accidents more possible, even in the Internet age. As a result, Chinese bureaucrats habitually hide scandals (such as mine disasters, chemical spills, the 2003 SARS epidemic, and tainted milk powder) for fear of being held accountable by the ruling Communist Party or exposing their own illicit deals with companies involved. Under China's authoritarian system, superiors reward subordinates for strict compliance with goals established by authorities, like reducing mine disasters. Indeed, should a mining accident occur, the incentive to hide it is often stronger than the reward for managing it well, as any disaster is almost surely considered a liability.[42]

In November 2009, a mining accident in Heilongjiang killed at least 104 people. It is thought to have been caused by a methane explosion followed by a coal dust explosion. Three top officials involved with the mining company were promptly dismissed.

On August 30, 2012 an explosion killed 45 people at the Xiaojiawan coal mine in Sichuan province.[43][44] A few days later on September 3, 2012 14 miners were killed at Gaokeng Coal Mine in Jiangxi province.[45]

On March 29, 2013, a landslide trapped 83 people in the Gyama Mine in Tibet.[46]

On 4 January 2014 The Chinese Government stated that 1,049 people died in the year 2013, down 24 percent from 2012.[47]

Ecuador

About 300 people were killed on May 9, 1993 in the Nambija mine disaster in Ecuador.[48]

On October 15, 2010, shortly after Chile completed its historic, successful rescue of 33 miners who had been stuck underground in the San Jose mine for a record period of nearly 10 weeks, four workers were trapped in an Ecuadoran gold mine following a tunnel collapse. All were confirmed dead by October 20.[49]

France
Le Petit Journal illustration of the Courrières mine disaster

The Courrières mine disaster was the worst ever pit mine disaster in Europe. It caused the death of 1,099 miners (including many children) in Northern France on 10 March 1906. It seems that this disaster was surpassed only by the Benxihu Colliery accident in China on April 26, 1942, which killed 1,549 miners. A dust explosion, the cause of which is not known with certainty, devastated a coal mine operated by the Compagnie des mines de houille de Courrières (founded in 1852) between the villages of Méricourt (404 killed), Sallaumines (304 killed), Billy-Montigny (114 killed), and Noyelles-sous-Lens (102 killed) about two kilometres (one mile) to the east of Lens, in the Pas-de-Calais département (about 220 km, or 140 miles, north of Paris).

A large explosion was heard shortly after 06:30 on the morning of Saturday 10 March 1906. An elevator cage at Shaft 3 was thrown to the surface, damaging pit-head workings; windows and roofs were blown out on the surface at Shaft 4; an elevator cage raised at Shaft 2 contained only dead and unconscious miners.

    Netherlands

    The twelve mines in the Netherlands, four of which were state owned, were considered among the safest in the world, with only three larger accidents occurring during 70 years of mining:

    -On 13 July 1928 a methane gas explosion killed 13 miners in the state-owned mine Hendrik in Brunssum.

    -On 24 March 1947 13 miners from Staatsmijn Hendrik were killed in a fire caused by an overheated conveyor belt.

    -On 3 March 1958 7 miners lost their lives when a cave-in occurred at Staatsmijn Maurits in Geleen.

    New Zealand

    The most notable mining accident in New Zealand is the 1896 Brunner Mine disaster, which killed all 65 miners inside. On 19 November 2010, there were four explosions over nine days at Pike River mine; 29 miners were killed and two escaped with minor injuries.

    On 19 January 1967, there was an explosion in the Strongman Mine, near Greymouth, on the West Coast. 19 people were killed.[52]

    Poland
    Main article: List of mining disasters in Poland

    On November 25, 2006, the worst mining disaster occurred in modern Polish history, 23 miners lost their lives at Halemba Coal Mine, a colliery in the town of Ruda Slaska in the southern industrial province of Silesia. A methane explosion at a depth of 1,030 meters caused the November 21 tragedy. The miners were attempting to retrieve €17 million ($US22 million) worth of equipment from a tunnel when a blast caused the shaft to collapse. The tunnel was supposed to have been closed in March due to dangerously high methane concentrations, but was kept active because of the value of the equipment left behind.[53]

    Russia

    Several major mining accidents have happened in Russia, particularly the Ulyanovskaya Mine disaster of 2007, which killed at least 106 miners. On January 20, 2013, at least four miners have died and four more are missing following an accident at a Russian coal mine. The accident happened at a coal mine in the Kuznetsk Basin region of Russia, in western Siberia.[54]

    Spain

    The history of mining in Spain has left a number of major mining accidents with hundreds of victims. The majority of the accidents and casualties have happened in the North of Spain and are particularly related to coal mining, mainly due to the collapse of structures and gas explosions. Though, the worst recorded accident took place in Villanueva del Río, Sevilla, in the Southwest of the country on 28 April 1904, killing 63 people and leaving several more injured.[55]

    South Africa

    A number of major mining accidents happened in South Africa including the following accidents:

    • 437 deaths[56] on 21 January 1960 the Coalbrook mining disaster occurred at Coalbrook North colliery. Coalbrook North colliery was one of the underground collieries of Clydesdale (Transvaal) Collieries Limited and was situated near Sasolburg in the Orange Free State province[57][58]
    • 177 killed on 16 September 1986 at the Kinross gold mine in Evander, Mpumalanga. This is still the world's worst metal mining disaster.
    • 104 deaths on 10 May 1995 at Vaal Reefs number two shaft near Orkney, in the North West, was arguably one of the worst to befall mining in South Africa.
    • 64 deaths on 12 September 1983 at Hlobane Colliery near Vryheid, Kwa-Zulu Natal
    • 57 deaths on 12 September 1944 at Hlobane Colliery near Vryheid, Kwa-Zulu Natal[59]
    • 53 deaths on 13 May 1993 at Middelbult colliery. Middelbult colliery was and is still one of the underground collieries of Sasol Mining situated near the town of Secunda, Mpumalanga

    Taiwan

    The three worst mining accidents in Taiwan all happened in 1984:

    • On June 20, 1984, in Haishan Coal Mine in Tucheng District, a runaway mining cart struck a high voltage transformer and triggered an explosion. 72 miners died from carbon monoxide poisoning.[60]
    • On July 10, 1984, 103 miners died in Meishan Coal Mine in Ruifang District as a result of carbon monoxide poisoning caused by a fire started in the air compressor chamber.[61]
    • On December 5, 1984, an explosion occurred at Haishan Coal Mine No. 1 in Sanxia District. 93 miners died from carbon monoxide poisoning with only one survival who was rescued 93 hours after the initial explosion.

    Tanzania

    At least 56 miners were killed in April 1998 after heavy rains flooded tanzanite mine shafts.[62] Five people were killed in July 2013 after the tanzanite quarry they were working in the Mererani mining hills collapsed above their heads. A sixth was admitted to hospital in critical condition.[63]

    Turkey

    In March 1983, in the Armutçuk coal mine 103 miners died due to a methane gas explosion.[64]

    In March 1992 at the TCC Kozla mine, 263 miners were killed due to a firedamp explosion[65]

    In 2008 there was another disaster which resulted in one person losing their life. In November 2013, 300 workers barricaded the Zonguldak mine in order to protest the working conditions.

    During the year of 2009, in December killed 19 miners due to a methane gas explosion in Bursa Province.

    In 2010, there was a mining disaster in Zonguldak Province which resulted in the deaths of 30 workers in a coal mine. The explosion was caused by a firedamp explosion. Previous mining disasters have also occurred here, one in 1992 resulted in the deaths of 270 workers. This was the worst mining disaster until the Soma mine disaster.

    In May 2014, in Soma, Manisa there was a major mine collapse caused by an explosion. More than 302 workers lost their lives in the collapse and at least 80 workers were injured.[66][67][68][69]

    Unfortunately, in recent years the Turkish coal mining industry has been found to have the very worst safety record in the world, in terms of fatal accidents per million tons of coal produced. When using the "deaths per million tons of coal production" measure, on any given day, a Turkish coal miner is 360 times more likely to be killed in a Turkish mine than an American coal miner is in an American mine, and 5 times more likely to die from the lax mine safety standards of the Turkish mines than even a Chinese coal miner, whose country places with a distant second in terms of safety related deaths per million tons of coal produced.[70]

    United Kingdom

    England

    In England, The Oaks explosion remains the worst mining accident, claiming 388 lives on 12–13 December 1866 near Barnsley in Yorkshire although in the first and main explosion on 340 died, less than at the Hulton colliery but subsequent explosions claimed other lives during the night and the following day. The Hulton Colliery explosion at Westhoughton, Lancashire, in 1910 claimed the lives of 344 miners.[71] An explosion in 1878, at the Wood Pit, Haydock, Lancashire, killed over 200 workers, although only 189 were included in the 'official list'.[72] Another disaster that killed many miners was the Hartley Colliery Disaster, which occurred in January 1862 when the beam of the pumping engine broke suddenly and fell into the single shaft serving the pit. The beam blocked the shaft and entombed hundreds of miners. The final death toll was 204, most of whom were suffocated by the lack of oxygen.

    In the metalliferous mines of Cornwall, some of the worst accidents were at East Wheal Rose in 1846, where 39 workers were killed by a sudden flood; at Levant mine in 1919, where 31 were killed and many injured in a failure of the man engine; 12 killed at Wheal Agar in 1883 when a cage fell down a shaft and seven killed at Dolcoath mine in 1893 when a large stull collapsed.[73][74][75]

    Scotland

    The worst mining accident in Scotland is the 1877 Blantyre mining disaster in Blantyre, Lanarkshire, which claimed 207 lives. Other fatal incidents occurred in the town in 1878 and 1879.[76]

    Another serious incident occurred in the small Ayrshire mining village of Knockshinnoch in September 1950. For several tense days rescuers battled bravely against all odds to reach the 129 men trapped deep underground when a field above where they were working caved-in, flooding the mine workings with thick liquid peat, cutting off all means of escape. 116 were rescued but 13 died.[77] A film, The Brave Don't Cry, was made about the distaster in 1952.[78]

    Wales
    Crowd gathering at the pit head of the Senghenydd Colliery after the explosion in October 1913

    During the period 1850 to 1930 the South Wales coalfield had the worst disaster record. This was due to the increasing number of mines being sunk to greater depths into gas-containing strata, combined with poor safety and management practices. As a result, there were nearly forty underground explosions in the Glamorgan and Monmouthshire areas of the coalfield during this time. Each accident resulted in the deaths of twenty or more workers – either directly in the explosion or by suffocation by the poisonous gases formed. The total death toll from these disasters was 3,119 people. The four worst accidents in Wales were:

    Some collieries, e.g. Morfa Colliery,[80] near Port Talbot, Glamorgan, and Black Vein Colliery, Risca, Monmouthshire, suffered three disasters before they were closed for being unsafe.

    United States

    The Fraterville mine disaster occurred on May 19, 1902 killing 216 miners making it one of the worst in American history. Fraterville is located in western Anderson County, Tennessee.

    The Monongah Mining Disaster was the worst mining accident of American history; 362 workers were killed in an underground explosion on December 6, 1907 in Monongah, West Virginia.

    The Cross Mountain Mine disaster occurred on December 9, 1911 near the community of Briceville, Tennessee, killing 84 miners.

    The First Dawson Disaster was a mining accident on October 22, 1913 in Dawson, New Mexico in which 263 men died (146 were Italian and 36 were Greek).

    The Second Dawson Disasters was a mining accident on February 8, 1923 in Dawson, New Mexico in which 123 men died.

    The Speculator Mine Disaster occurred in the copper mines of Butte, Montana on June 8, 1917. An electric cable being lowered into the mine was accidentally ignited at 2,500 feet below the surface. The fire quickly climbed the cable, in turn igniting the shaft. The shaft thus became a chimney, eliminating the mine's primary source of oxygen. Nearly all of the 168 fatalities were due to asphyxia. It remains the deadliest underground hard rock mining event in American history.

    The Cherry Mine disaster was a fire in the Cherry, Illinois, coal mine in 1909, and surrounding events, in which 259 men and boys died.

    The Millfield Mine Disaster 1930 in Ohio killed 82 men.

    From 1880 to 1910, mine accidents claimed thousands of fatalities. Where annual mining deaths had numbered more than 1,000 a year during the early part of the 20th century, they decreased to an average of about 500 during the late 1950s, and to 93 during the 1990s.[81] In addition to deaths, many thousands more are injured (an average of 21,351 injuries per year between 1991 and 1999), but overall there has been a downward trend of deaths and injuries.

    In 1959, the Knox Mine Disaster occurred in Port Griffith, Pennsylvania. The swelling Susquehanna River collapsed into a mine under it and resulted in 12 deaths. In Plymouth, Pennsylvania, the Avondale Mine Disaster of 1869 resulted in the deaths of 108 miners and two rescue workers after a fire in the only shaft eliminated the oxygen in the mine. Federal laws for mining safety resulted from this disaster. Pennsylvania suffered another disaster in 2002 at Quecreek, 9 miners were trapped underground and subsequently rescued after 78 hours. During 2006, 72 miners lost their lives at work, 47 by coal mining. The majority of these fatalities occurred in Kentucky and West Virginia, including the Sago Mine Disaster.[82][83] On April 5, 2010, in the Upper Big Branch Mine disaster an underground explosion caused the deaths of 29 miners.

    The U.S. Bureau of Mines was created in 1910 to investigate accidents, advise industry, conduct production and safety research, and teach courses in accident prevention, first aid, and mine rescue. The Federal Coal Mine Health and Safety Acts of 1969 and 1977 set further safety standards for the mining. Since the closure of the U.S. Bureau of Mines in 1996, this research function has been carried on by the National Institute for Occupational Safety and Health (NIOSH). NIOSH maintains a list of mine disasters which occurred in the United States since 1839.[84]
