摘　　要：为了研发低浓度瓦斯抽放系统的安全设备,分别在DN500 mm和DN700 mm的试验管道内进行了瓦斯爆炸传播试验。通过动态信号综合测试系统采集了爆炸火焰和压力波的试验数据。试验结果表明:管道内瓦斯爆炸压力波峰值与传播距离呈二次函数关系,爆炸火焰到达时间与传播距离呈对数函数关系,且火焰传播速度随传播距离的增长而增大,管道直径对爆炸的传播有明显影响。In order to research and develop the safety equipment of the low content gas drainage system,the gas explosion transmission tests were conducted in the DN500 mm and DN700 mm test pipeline individually.The dynamic signal comprehensive test and measurement system was applied to collect the test data of the explosion flame and pressure wave.The test results showed that there would be secondary function relationship between the gas explosion pressure peak and the transmission distance in the pipeline and there ...
