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.
The Monongah mining disaster of Monongah, West Virginia occurred on December 6, 1907, and has been described as "the worst mining disaster in American history." 362 miners were killed. The explosion occurred in Fairmont Coal Company’s No. 6 and No. 8 mines, and was one of the contributing events leading to the creation of the United States Bureau of Mines.
The Senghenydd colliery disaster, also known as the Senghenydd explosion, occurred at the Universal Colliery in Senghenydd, near Caerphilly, Glamorgan, Wales, on 14 October 1913. The explosion, which killed 439 miners and a rescuer, is the worst mining accident in the United Kingdom. Universal Colliery, on the South Wales Coalfield, extracted steam coal, which was much in demand. Some of the region's coal seams contained high quantities of firedamp, a highly explosive gas consisting of methane and hydrogen.
The Gresford disaster occurred on 22 September 1934 at Gresford Colliery, near Wrexham, Denbighshire, when an explosion and underground fire killed 266 men. Gresford is one of Britain's worst coal mining disasters: a controversial inquiry into the disaster did not conclusively identify a cause, though evidence suggested that failures in safety procedures and poor mine management were contributory factors. Further public controversy was caused by the decision to seal the colliery's damaged sections permanently, meaning that only eleven of those who died were recovered.
On March 25, 1947, the Centralia No. 5 coal mine exploded near the town of Centralia, Illinois, killing 111 people. The Mine Safety and Health Administration of the United States Department of Labor reported the explosion was caused when an underburdened shot or blown-out shot ignited coal dust. The US Department of Labor lists the disaster as the second worst US mining disaster since 1940 with a total of 111 men dead.
Almy was a coal mining camp in Uinta County, Wyoming, United States, near the town of Evanston. In 1881, an explosion killed 38 miners in the Central Pacific Mine, marking the first mine explosion west of the Mississippi River. Another explosion killed 13 in 1886, and a third explosion in Red Canyon in 1895 killed 62 miners, the third worst mining disaster in Wyoming history. Following the second explosion, the Wyoming territorial legislature established the office of the state mining inspector, which eventually shut down the Almy mines in the 1940s after it was deemed too dangerous to mine there.
The Castle Gate mine disaster occurred on March 8, 1924, in a coal mine near the town of Castle Gate, Utah, located approximately 90 miles southeast of Salt Lake City. All of the 171 men working in the mine were killed in the series of three violent explosions. One worker, the leader of the rescue crew, died from carbon monoxide inhalation while attempting to reach the victims shortly after the explosion.
The Minnie Pit disaster was a coal mining accident that took place on 12 January 1918 in Halmer End, Staffordshire, in which 155 men and boys died. 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.
Albion Colliery was a coal mine in South Wales Valleys, located in the village of Cilfynydd, one mile north of Pontypridd.
Gresford Colliery was a coal mine located a mile from the North Wales village of Gresford, near Wrexham.
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. Twenty-nine out of thirty-one miners at the site were killed. The coal dust explosion occurred at 3:27 pm. The accident 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 Scofield Mine disaster was a mining explosion that occurred at the Winter Quarters coal mine on May 1, 1900. The mine was located at 39°42′57″N111°11′17″W near the town of Scofield, Utah. In terms of life lost, it was the worst mining accident at that point in American history. The explosion is also a key element in the plot of the Carla Kelly novel My Loving Vigil Keeping.
The Harwick Mine disaster was a mining accident on January 25, 1904 in Cheswick, Pennsylvania, some sixteen mi (26 km) north of Pittsburgh in the western part of the state. The blast killed an estimated 179 miners and 2 aid workers. The disaster ranks among the ten worst coal mining disasters in American history. One community especially impacted was the Hungarian community in Homestead, Pennsylvania. Fifty-eight of the members of the First Hungarian Reformed Church of Homestead—a full third of the congregation—died in the explosion.
The Peckfield pit disaster was a mining accident at the Peckfield Colliery in Micklefield, West Yorkshire, England, which occurred on Thursday 30 April 1896, killing 63 men and boys out of 105 who were in the pit, plus 19 out of 23 pit ponies.
The Pickands Mather Group is an American company which provides shipping of coal and other bulk commodities, and the purchase, sale, and marketing of bulk coal. Founded in 1883 as Pickands Mather & Company, it once had the second largest shipping fleet on the Great Lakes in the 1910s and 1920s. The company was purchased by the Diamond Shamrock Corporation in 1968, which in turn sold it to the Moore-McCormack Resources in 1973. Moore-McCormack sold Pickands Mather's mining interests to Cleveland-Cliffs in 1986. Moore-McCormack then spun off the Interlake Steamship Company to James Barker and Paul R. Tregurtha in 1987. Pickands Mather was sold to a management group in 1992, and continues to operate as a private company.
The Coal Mines Act 1911 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.
The Maypole Colliery disaster was a mining accident on 18 August 1908, when an underground explosion occurred at the Maypole Colliery, in Abram, near Wigan, then in the historic county of Lancashire, in North West England. The final death toll was 76.
