摘要
应用Ｃ－Ｊ爆轰理论和质量、动量、能量守恒原理， 针对煤矿巷道瓦斯变绝热指数建立了雨贡纽方程和瑞利方程，在此基础上分析了煤矿巷道瓦斯爆炸的条件和可能过程．建立了煤矿巷道瓦斯Ｃ－Ｊ爆轰参数计算公式，提出了激波点燃瓦斯混合气的条件和最小理论马赫数Ｍｍｉｎ的表达式．计算了煤矿巷道几种瓦斯浓度情况下爆压、爆温、爆速等爆轰参数和相应的点燃瓦斯混合气的最小理论马赫数Ｍｍ ｉｎ．
Using C J explosion theory and conservation of mass, momentum, energy, the author introduced Hugoniot equation and Rayleigh equation of changeable adiabatic index to gas in coal gangway and analysed conditions and process of gas explosion in coal gangway. The calculating eqations of methane gas C J explosion paramentes were established. The conditions of air methane mixire combustion by shock wave and minimum theorytical Mach number of shock wave were put forward. Finally, some parameters of methane gas explosion pressure, temperature, speed and minimum theorytical Mach number of air methane mixire combustion by shock wave under different methane concentrations were calculated.
