摘要
在火焰加速管中,对不同障碍物情况下的纯瓦斯、有沉积煤尘的瓦斯燃烧过程进行了实验研究。结果表明,障碍物存在时,瓦斯火焰、瓦斯煤尘复合火焰的传播速度迅速提高,并伴随有巨大的爆炸声,且障碍物尺寸越大、个数越多火焰传播加速现象越显著。因此,应尽量减少矿井巷道中的障碍物。
The combustion process of gas with coal dust or gas with different obstacles in fire-accelerating pipelines has been experimentally studied. The result shows that when obstacles are present in the pipeline, the speed of gas flame or the compound flame of gas and coal dust increases dramatically and it is accompanied by loud explosive sounds. It also shows that the larger the obstacles are and the greater their number is, the more noticeably the transmitting speed of flame accelerates. Therefore, the barriers in tunnels of coal mines should be reduced to the smallest number possible.
