CDC - Mining Feature - Coal Mine Explosion Prevention - NIOSH

2011-12-09  There are two main types of coalmine explosions: methane and coal dust. Methane explosions occur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below its explosion point. Likewise, fine particles of coal dust in the right concentration that contact a source of heat can also be explosive.

Causes of coal mine explosions Peyton Law Firm, P.L.L.C.

2018-12-03  Methane levels in coal mines are supposed to be kept below 1 percent. Unfortunately, there are areas that are difficult to reach. Coal dust explosions in coal mines are usually caused by methane gas explosions. Dust must be very concentrated to explode. When methane combustion leads to a coal dust explosion, the results can be devastating. Workers sprinkle lime dust over coal dust

Coal Mining Disasters The Canadian Encyclopedia

2014-09-04  The first major Canadian coal mining disaster was at Westville, Pictou County, Nova Scotia, on 13 May 1873 after a shot of explosive ignited methane at the coal face. The fire caused a gas explosion, which, fed by coal dust, ripped through the mine and set off further explosions, killing workers and firefighters attempting their rescue.

The Westray coal mine explodes, killing the 26 miners ...

2017-10-13  The coal seam there had been mined for 200 years with a long history of explosions. The nearby Allan mine, which closed in 1951, experienced eight methane explosions in its 40-years of operations. The Westray death toll was Canada’s worst mining disaster since the 1958 “bump” in the Springhill coal mine that claimed the lives of 75 miners.

Westray Mine Explosion, Plymouth, 1992 Museum of Industry

A long history of methane explosions in the Foord coal seam meant that the risks were high in mining that wide band of coal. In April 1991, digging at the Curragh Resources-owned Westray Mine had reached the infamous Foord, the cause of innumerable roof falls, fires, and explosions in other collieries in the past. In this modern mine, the assurance was that state-of-the-art technology and ...

Explosion Prevention in Mining

2017-10-13  Explosions in coal mines as a result of coal dust accumulation is not as common as that which is associated with methane combustion, as a very high concentration of coal dust must be suspended within the air. Methane-coal dust hybrid mixture explosions, can also occur with more severe characteristics as compared to either explosion alone.

Explosion Hazards From Methane Emissions Related to ...

Explosions in U.S. coal mines have caused death and injury to miners and destruction of workings since the first reported explosion in 1810. These explosions are caused when buildups of explosive gas and/or dust in the mine are ignited by the presence of a flame or spark. Methane gas is inherently generated and held by adsorption in coal and is normally liberated during mining. Because this ...

Methane in Underground Mines • MineARC Systems

2018-12-13  Coal Mine Methane (CMM) is a blend of air and Methane released from rock strata as a direct result of mining activities. Methane trapped within a coal seam emerges in a mine after layers of a coal face are removed. Additionally, Methane can seep out of vents from abandoned mines, or appear after a rock collapse from a post-mining area.³
