针对煤矿井下瓦斯爆炸事故容易造成大量的人员伤亡的问题,采用大型巷道试验系统,研究了100 m3的瓦斯空气混合气体发生爆炸后对不同传播距离内SD大鼠的损伤效应。通过研究得出:瓦斯爆炸产生的爆炸冲击伤害是造成动物死亡的主要原因,即使远在240 m处,SD大鼠也会由于爆炸冲击而出现死亡。井下100 m3瓦斯爆炸过程中,爆炸火焰波及到了40 m的范围,安装在40 m处笼子内的SD大鼠除了受到爆炸冲击伤害外,还受到了高温灼伤的伤害。研究结论可为煤矿井下瓦斯爆炸事故的应急救援和抢救提供理论依据。

According to the problem that a gas explosion accident occurred in the underground coal mine would easily cause a large number of the casualties, a large mine roadway test system was applied to study the damage effect of the SD rats within different propagation distances after the explosion of 100 m3 gas air mixed gas occurred. The study showed that the explosive impact damage from the gas explosion occurred was the main cause of the animal death. Even at a far distance of 240 m,the SD rats would be killed due the explosion impact. During the 100 m3 gas explosion process in the underground mine,the explosion flame had an impact range of 40 m. The SD rats in the cages set within the 40 m had the explosion impact damage and also were damaged by the high temperature burning. The conclusion of the study could provide important theoretical basis to the emergency rescue and rescue of the gas explosion accident occurred in the underground coal mine.
