摘　　要：文章建立了瓦斯爆炸冲击波的管道物理模型,利用Euler形式的动量、质量、能量守恒方程和热力学方程从理论上解析了瓦斯爆炸过程中爆炸冲击波与掘进巷道壁面相互作用中正反射和斜反射时波阵面上的各个参数,并给出了计算公式和简化公式。The physical model of shock wave propagation in the tube during gas explosion is set up in this paper. Using the Conservation Law of mass, momentum, energy in the form of Euler and equation of the thermodynamics, the interaction between the shock wave and the wall surface of the excavation roadway during the gas explosion is discussed. Theoretically, the parameters of the wave front in the normal and oblique reflection of shock wave are deduced. Meanwhile, some computational and simplified formula are given in this paper.
