Abstract： The killing and injury effects of gas explosion shock wave on mouse in an open space pipeline is tested experimentally. When the methane volume fraction is 10%, the maximum explosion pressure is 0.264 MPa and the injury is the most serious. Specially, some designed obstacles put in the open space pipeline are conducive to producing more stronger gas explosion shock wave. Accordingly, the injury effect of methane explosion on mouse is enhanced under obstacles condition.When the methane volume fraction is 10%, the maximum explosion pressure can reach 0.298 MPa under obstacles condition. It can be concluded that to reduce explosive accident impact, the obstacles in coal mine should be avoided. With the explosions increasing, the death pressure of mouse decreases.

摘要： 通过实验测试了管道式气体爆炸冲击波对置于管道内的白鼠的杀伤作用， 当甲烷体积分数为10%时， 爆炸产生的最大压力为0.264 MPa， 白鼠受伤最严重。 将一些特制的障碍物置于管道可产生更强的冲击波， 这有助于增强甲烷爆炸对白鼠的杀伤作用。 当甲烷体积分数为10%时， 有障碍物条件下的最大爆炸压力可达到0.298 MPa。 由此可知， 为减小煤矿中事故冲击力， 应尽量避免障碍物的存在； 随爆炸次数增加， 白鼠致死压力减小。
