摘要
为预防瓦斯爆炸造成的人员伤亡,研究井下爆炸波对动物的损伤规律。将白鼠用笼子固定放置在管道式气体爆炸测试装置内,点燃管道内甲烷-空气混合气体,通过改变试验条件,对不同压力下爆炸冲击波对白鼠杀伤作用进行研究。结果表明:白鼠因受到不同浓度甲烷爆炸冲击而损伤不同。甲烷爆炸对白鼠杀伤作用随浓度先增大,后减小,障碍物存在加剧了甲烷爆炸对小白鼠的杀伤作用;管道内致白鼠死亡的爆炸压力明显小于空旷环境下;白鼠受爆炸冲击次数增多,其死亡对应的爆炸压力比只受一次爆炸冲击时下降。
In order to prevent human injury from shock wave in mine,simulation experiments were carried out. CH4-air mixtures were ignited in a gas explosion experimental equipment where white mice fixed in cage were put. Mice injuries were studied for different shock wave pressures. The results show that injury of mice is affected heavily by CH4volume fraction in the mixture,that casualty rate of mice increase first and then decrease with the increase of methane volume fraction that casualty rate of mice was exacerbated by obstacles,that lethal pressure in pipeline is lower than lethal pressure on ground,and that lethal pressure decrease with explosion times white mice have experienced successively.
