模拟煤矿巷道内瓦斯爆炸特性的试验研究

Experiment and Study on Gas Explosion Features in Simulated Mine Roadway

针对近年来煤矿瓦斯爆炸事故频发的情况,利用不同长度的水平管道来模拟煤矿巷道瓦斯爆炸,研究瓦斯的爆炸极限、最大爆炸压力及其浓度、最大爆炸压力上升速率等爆炸特性,同时分析了瓦斯爆炸压力在管道内的变化情况,为预防煤矿巷道内的瓦斯爆炸提供理论依据。

According to the conditions of the mine gas explosion accidents frequently occurred in the recent years, the horizontal pipelines with different lengths were applied to simulate the gas explosion in the mine roadway to study the explosion limits of the gas explosion, the max explosion pressure and density, the max explosion pressure rising velocity and explosion features. The paper also analyzed the variation conditions of the gas explosion pressure in the pipeline in order to provide the theoretical references to prevent the gas explosion in the mine roadway.
