| 摘 要： | 瓦斯爆炸是煤矿重大灾害之一。矿井火区中微量气体成分对瓦斯爆炸极限及其它爆炸参数有显著影响,利用自行研制的配气系统和20 L球形爆炸系统,选用3种特殊气体成分作为代表气体,通过实验进行了对比研究。实验结果表明,氢气、异丁烷、正己烷都会对瓦斯爆炸特性产生较大影响,其中正己烷对甲烷爆炸下限影响较大,氢气对甲烷爆炸上限影响较小,最大爆炸压力指数影响的顺序为氢气>正己烷>异丁烷。

| Abstract: | In coal mine,gas explosion is one of the major disasters.Trace gas composition in fire district effects on the methane explosion limits and other parameters of the explosion significantly.In this paper,the issue has been comparative studied,selecting three special gases as the target gases,using self-developed gas distribution systems and 20L spherical blast system.The experimental results show that Hydrogen,Isobutane and N-hexane could all have significant impact on the gas explosion.N-hexane has a great i... |
