摘要
分析了煤矿矿井可燃气体发生爆炸的原因,对可燃性混合气体的爆炸极限进行了计算,分析了火区封闭后可燃气体爆炸的危险性,研究了各种燃烧及爆炸抑制技术。结果表明:采用凝胶注入法可有效降低煤矿温度,减缓煤氧反应,降低爆炸危险。
This paper analysizes the reason of coal well explosion, calculates the explosive limitiation of flammable gas, analysizes explosive fatalness after fire zone close down.Sorts of control technology of explosion and blunt are studied. It shows that infuse gel can reduce coal well temperature, coal and oxygen reaction and explosive fatalness greatly.
