| 摘 要： | 在断面为7.2 m2、长为658 m的实验巷道内，用cs2092H多通道动态数据采集分析仪，模拟煤矿掘进巷道，对瓦斯、煤尘爆炸过程中的爆炸冲击波能量、传播速度、衰减规律以及爆炸灾害的波及范围进行了实验研究.结果表明，瓦斯、煤尘爆炸压力波衰减慢，爆炸传播距离远，且传播距离随瓦斯数量以及瓦斯、煤尘分布的变化而变化.与瓦斯爆炸相比，煤尘爆炸的剧烈程度强，坑道中煤尘的焦化明显，且可燃物灼烧情况可作为瓦斯煤尘爆炸的爆源点确认判据.

| Abstract: | By using cs2092H multichannel dynamic data collecting and analyzing instrument,gas and coal dust explosion process experiment was done in the experimental lane whose section was 7.2 m2 and the length was 658 m,which was used to simulate drifting lane in coal mine.Including the measured characters as: energy,propagation speed and weakening law of explosion blast wave,range of explosion hazard and so on.The result shows that gas and coal dust explosion propagation distance is long while the pressure wave weak... |
