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。
Aiming at the complexity of fire and shock wave propagation law after mine gas explosion and the serious disasters brought to safety production, the numerical simulation and experimental research are combined to analyze the fire and shock wave propagation laws in mine in detail. Firstly, the parameters of temperature and velocity in flame flow field under different working conditions were obtained by hydrodynamic calculation program. Then the shock wave pressure and velocity under different working conditions were experimentally studied by using shock tube and pressure test system.
