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.
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 Oaks explosion, which happened at a coal mine in West Riding of Yorkshire on 12 December 1866, remains the worst mining disaster in England. A series of explosions caused by firedamp ripped through the underground workings at the Oaks Colliery at Hoyle Mill near Stairfoot in Barnsley killing 361 miners and rescuers. It was the worst mining disaster in the United Kingdom until the 1913 Senghenydd explosion in Wales.
The Felling Colliery in Britain, suffered four disasters in the 19th century, in 1812, 1813, 1821 and 1847. By far the worst of the four was the 1812 disaster which claimed 91 lives on 25 May 1812. The loss of life in the 1812 disaster was one of the motivators for the development of miners' safety lamps such as the Geordie lamp and the Davy lamp.
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.
The South Maitland coalfields was the most extensive coalfield in New South Wales until the great coal mining slump of the 1960s. It was discovered by Lieutenant-Colonel William Paterson's party when they were engaged in an exploratory visit to the Hunter River Valley during July 1801.
Kurri Kurri is a small town in the Hunter Region of New South Wales, Australia, in the Cessnock LGA. At the 2016 census, its population was 6,044. Kurri Kurri is the largest town in a group of towns and hamlets, including Stanford Merthyr, Pelaw Main, Weston, Abermain and Heddon Greta, called Kurri Kurri – Weston by the ABS. Its estimated population was 17,241 at 2016 census.
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.
Clifton Hall Colliery was one of two coal mines in Clifton on the Manchester Coalfield, historically in Lancashire which was incorporated into the City of Salford in Greater Manchester, England in 1974. Clifton Hall was notorious for an explosion in 1885 which killed around 178 men and boys.
The South Maitland Railway was once an extensive network of privately owned colliery and passenger railway lines which served the South Maitland coalfields in the Hunter Region of New South Wales, Australia and were the second last system in Australia to use steam haulage, having used steam locomotives until 1983.
The Richmond Vale Railway was a 4 ft 8+1⁄2 in colliery railway line in the Hunter Valley of New South Wales, Australia, servicing coal mines at Minmi, Stockrington, Pelaw Main and Richmond Main. It was over 26 km (16 mi) long and passed through three tunnels, and was the last commercially operated railway in Australia to use steam locomotives.
Pelaw Main is a hamlet a few kilometres south-west of Kurri Kurri, in the Hunter Region of New South Wales, Australia. It owes its origins entirely to the colliery there of the same name. It had a population of 1,027 in 2011
The West Stanley Pit disasters refers to two explosions at the West Stanley colliery. West Stanley colliery was a coal mine near Stanley, with the mine opening in 1832 and closing in 1936. Over the years several seams were worked through four shafts: Kettledrum pit, Lamp pit, Mary pit and New pit. In 1882 an underground explosion killed 13 men and in 1909 another explosion killed 168 men.
Gresford Colliery was a coal mine located a mile from the North Wales village of Gresford, near Wrexham.
The Bedford Colliery disaster occurred on Friday 13 August 1886 when an explosion of firedamp caused the death of 38 miners at Bedford No.2 Pit, at Bedford, Leigh in what then was Lancashire. The colliery, sunk in 1884 and known to be a "fiery pit", was owned by John Speakman.
The Cadeby Main Pit Disaster was a coal mining accident on 9 July 1912 which occurred at Cadeby Main Colliery in Cadeby, West Riding of Yorkshire, England, killing 91 men. Early in the morning of 9 July an explosion in the south-west part of the Cadeby Main pit killed 35 men, with three more dying later due to their injuries. Later in the same day, after a rescue party was sent below ground, another explosion occurred, killing 53 men of the rescue party.
This is a partial glossary of coal mining terminology commonly used in the coalfields of the United Kingdom. Some words were in use throughout the coalfields, some are historic and some are local to the different British coalfields.
The Cymmer Colliery explosion occurred in the early morning of 15 July 1856 at the Old Pit mine of the Cymmer Colliery near Porth, Wales, operated by George Insole & Son. The underground gas explosion resulted in a "sacrifice of human life to an extent unparalleled in the history of coal mining of this country" in which 114 men and boys were killed. Thirty-five widows, ninety-two children, and other dependent relatives were left with no immediate means of support.
The 1923 Bellbird Mining Disaster took place on 1 September 1923 when there was a fire at Hetton-Bellbird coal mine, known locally as the Bellbird Colliery or mine. The coal mine was located near the village of Bellbird, which is itself three miles southwest of Cessnock in the Northern coalfields of New South Wales, Australia. The accident occurred in the No. 1 Workings of the mine and resulted in the deaths of 21 miners and their horses. Subsequently there was a thorough investigation into the causes of the accident which resulted in legislative changes that were implemented in an effort to improve worker safety in Australian coal mines. These efforts culminated with the Mines Rescue Act 1925 which established standards for mine rescue operations in New South Wales (NSW) province. At the time of the disaster the mine employed 538 people including 369 who worked underground. The accident killed 21 miners and caused legislation changes.
