Methane is extremely flammable and may form explosive mixtures with air. Methane gas explosions are responsible for many deadly mining disasters. [84] A methane gas explosion was the cause of the Upper Big Branch coal mine disaster in West Virginia on April 5, 2010, killing 29. [85]
All of the workers were either at blocks B or C of the mine during the explosion. During the initial rescue, large amounts of methane gas were discharged within both blocks. The emission rate was greater in Block B, where rescuers were unable to enter. [9] Forty-seven workers were in Block B and 22 were in Block C during the explosion. [10]
A balloon filled with gaseous hydrogen exploding.. A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.
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 [ 1 ] 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 (3:19 GMT ).
Damp is the collective name given to all gases (other than air) found in coal mines in Great Britain and North America. [1]As well as firedamp, other damps include blackdamp (nonbreathable mixture of carbon dioxide, water vapour and other gases); whitedamp (carbon monoxide and other gases produced by combustion); poisonous, explosive stinkdamp (hydrogen sulfide), with its characteristic rotten ...
Methane gas accumulation inside the mine caused the explosion and trapped the workers as a portion of the mine collapsed. [5] [6] During the search and rescue operation, five rescue workers fell unconscious due to methane gas, but another team managed to save them. Unfortunately, the six miners had already died by the time rescue teams arrived.
Aliso Canyon SS 25 wellhead, December 17, 2015. Note subsidence craters at center, apparently from the attempts to plug the leaking well. The Aliso Canyon gas leak (also called Porter Ranch gas leak [1] and Porter Ranch gas blowout [2]) was a massive methane leak in the Santa Susana Mountains near the neighborhood of Porter Ranch in the city of Los Angeles, California.
The Pasta de Conchos mine disaster occurred at approximately 2:30 a.m. CST on February 19, 2006, after a methane explosion within a coal mine near Nueva Rosita, San Juan de Sabinas Municipality, in the Mexican state of Coahuila. The mines were run by Grupo México, the largest mining company in the country. It was estimated that 65 miners, who ...
