摘要: 为探究不同类型管道内瓦斯爆炸冲击波传播规律,利用L型、T型和十字型试验管道模拟井下巷道结构,采用瓦斯燃烧爆炸测试系统进行瓦斯爆炸模拟试验,监测管道内不同位置的压力值,研究不同类型管道内瓦斯爆炸冲击波在转弯和分岔结构前后的压力变化规律。试验发现:L型管道转弯处外侧管壁爆炸冲击波压力峰值最高;T型和十字型管道的分岔结构可以降低L型管道转弯处的压力峰值,且T型分岔结构的降低效果更好;L型、T型和十字型管道对冲击波压力的衰减效果依次增强。

Abstract: In order to explore the propagation law of gas explosion shock waves in different types of pipeline,using the pipes of "L" type,"T" type and cross type to simulate the underground roadway for experiments of gas explosion,which using gas combustion explosion test system.Pressure values at different positions in the pipe are detected,pressure variation rule of gas explosion shock wave in the front and rear position of turns and bifurcation structures of different pipe types is studied.The experimental results show that the pressure peak value is the highest on the lateral wall of "L" pipe bend.The bifurcation structure of "T" type and cross pipe can effectively improve the pressure build-up,but the degree of improvement for cross-shaped pipe is less than "T" pipe.The damping effect of shock wave pressure and speed on "L" type,"T" type and cross type pipes is gradually enhanced.

Key words: gas explosion, shock wave, experiment, pressure, monitoring point
