摘　　要：针对矿井瓦斯爆燃后火灾和冲击波传播规律的复杂性以及给安全生产带来的重大灾害,采用数值模拟和实验研究相结合的方法,分别对矿井火灾和冲击波的传播规律进行较为详细地研究。首先利用流体力学计算程序得到不同工况下火焰流场中温度和速度参数;而后利用激波管及压力测试系统对不同工况下冲击波压力和速度进行了实验研究。The complexity of the mine gas explosion after fire and shock wave propagation and major disasters brought to safety production, using the method of numerical simulation and experimental research of combining, respectively in detail research on the propagation law of mine fire and shock wave. First, by using a computational fluid dynamics program obtained under different conditions of temperature and velocity parameters of flame flow field; then using shock tube and pressure test system under the different condition of shock wave pressure and velocity was studied.
