摘要
煤矿在煤炭生产过程中有瓦斯和煤尘产生,当瓦斯和煤尘达到一定浓度时,遇到足够能量的火源,就要发生瓦斯和煤尘爆炸事故。瓦斯和煤尘爆炸事故是煤矿危害最大的事故之一,能直接造成重大的人身伤亡和经济损失,对煤矿电气火花引起瓦斯与煤尘爆炸事故进行了分析,提出了其预防措施。
Coal mine gas and coal dust produced in the process of coal production, when the gas and coal dust concentration reaches a certain degree, have enough energy to fire, explosion accidents of gas and coal dust. The explosion accident of gas and coal dust is one of the largest coal mine accident harm, can directly cause casualties and the economic loss of great people, the gas explosion and coal on the coal mine electrical spark causes were analyzed, and put forward the prevention measures.
