At present, more than 90 rescue workers have gone down the well to rescue, and more than 30 medical workers rushed to the scene of the accident, the cause of which is under further investigation。
A lot of people is a stranger to carbon monoxide overrun the word, at ordinary times daily carbon monoxide is common sense to stay at home in the gas cylinder leaks family coal gas to produce a large amount of carbon monoxide, also is good to know what is carbon monoxide overrun, don't know what exactly does this harm so today electric heat transfer explain our country coal mine safety rules regulation: carbon monoxide concentration in working face should not exceed 0.0024%, when the underground carbon monoxide concentrations over coal mine safety rules Regulation, in addition to carbon monoxide by blasting and explosive, it is probably caused by coal seam spontaneous combustion or other fire, need to take relevant measures that is carbon monoxide concentrations need to control in 0.0024%, if more than, downhole coal oxidation and spontaneous combustion of carbon monoxide, are likely to face air leakage into face, destroy the production environment, harm the underground worker health, affect the normal production of working face。
A carbon monoxide overrun reason analysis (1) coal seam occurrence of a large amount of carbon monoxide, after mining the release to the front of the face (2) mining face blasting technology lane leading to coal, because of the eme slow oxidation of carbon monoxide (3) after the mining face, because of the top-coal is not fully released, engendered by the traces of a lot of coal oxidation traces of carbon monoxide (4) adjacent goaf coal oxidation of carbon monoxide spread to the working face, etc。
