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 mines produce coal gas and coal dust during coal production. When gas and coal dust reach a certain concentration, gas and coal dust explosion accidents occur when a sufficient energy source of fire is encountered. Gas and coal dust explosion accidents are one of the most serious accidents in coal mines, which can directly cause serious personal injury and economic loss, analyze the gas and coal dust explosion accidents caused by electrical sparks in coal mines, and put forward their preventive measures.
