煤矿瓦斯爆炸事故的电气诱因与对策

Electrical Incentive for Explosion Hazard Caused by Coal-mine Gas and Its Countermeasures

从电气角度分析了煤矿瓦斯爆炸的“导火索”多源于矿井诸多电气设备缺陷、故障以及井下作业人员违章操作所产生的电气火花、电弧或高温 ,并提出了降低煤矿瓦斯爆炸的电气诱因的措施。

The author summarizes the causes of some explosions happened in coalmine that they are mostly caused by the defect of the electrical equipments used in the shaft, electrical spark,ɑrc or high temperɑture which may cɑused by the workers' unprofessional operation. Aimed at these causes, some effective procedures are proposed to depress the electrical incentive to the coal-mine gas explosion.
