矿井瓦斯与反火炉煤气掺混应用的安全性研究

Safety research on mixed application of mine gas and fire-reversed stove gas

在矿井瓦斯抽放量因某种原因减少的情况下,为了保证瓦斯用户的正常使用,根据反火炉煤气和矿井瓦斯的爆炸特性,以及混合气体爆炸特性的计算方法,提出了将这2种气体进行掺混使用的实施方案。首先从理论上对反火炉煤气和矿井瓦斯掺混应用进行可行性分析,然后在不同条件下进行了大量的模拟试验,并对试验数据和理论计算结果进行比较、分析。结果表明,用合格的反火炉煤气与矿井瓦斯进行不同比例掺混,均可以安全使用。

When the mine gas drainage quantity reduced for some reason, to ensure for normal utilization of the gas for residents, accord- ing to the explosion features of the fire-reversed stove gas and mine gas and the calculation method of the mixed gas explosion features, the paper provided the implemented project of the two gas mixed utilization. It was first to give a feasibility analysis on the utilization of the fire-reversed stove gas and mine gas mixed in theory, then under different conditions, a lot of simulation tests were conducted, the com- parison and analysis were also conducted on the test data and the theoretical calculation results. The results showed that the qualified fire- reversed stove gas and mine gas could be mixed with different ratios and all would be utilized in safety.
