在分析煤尘—甲烷混合物爆炸危险性的基础上,通过试验确定出最容易引火的煤尘—甲烷混合物浓度,建立了检验煤矿许用炸药煤尘—甲烷混合物安全试验方法。
Based on the analysis of the explosion risk of coal dust-methane mixture, the concentration of coal dust-methane mixture, which is the easiest to fire, was determined through experiments and a safety test method for testing the coal dust-methane mixture of explosives used in coal mine was established.
