王海宾, 尉存娟. Study on Animal Injury of Gas Explosion in Pipeline under Obstacles Conditions[J]. 2011, 32(6): 727-731.
利用管道式气体爆炸测试装置
分别在光滑管道内和放有障碍物的水平管道内充入当量浓度的甲烷气体
对甲烷-空气混合气体的爆炸压力变化以及对动物的损伤进行了实验研究.实验结果表明
当量浓度气体爆炸使光滑管道内不同位置的小白鼠全部死亡
其内脏的损伤程度随着长径比的增大而明显加重.在管道内有障碍物的情况下
爆炸对小白鼠的杀伤程度明显加重
其体型严重变形
肝脏、肺损伤严重并导致死亡.实验结果对进一步研究煤矿瓦斯爆炸对生命的损伤和灾害预防有一定的借鉴作用.
The experiments on explosion pressure and animal injury were carried out with the mixture methane-air in the smooth pipe and obstacles pipe by the pipeline testing device of gas explosion.Experimental result shows that all white rats of different locations in smooth pipeline were dead of gas explosion in equivalent concentration
but the viscera damage of white rat was increased as the increasing of length-diameter ratio.Under the condition of obstacles
the damage of white rats was significantly critical and its body had serious distortion
the liver and lung damaged cause death.The experimental results give good advices to prevention and control of gas burst and injury of life.
