| 摘 要： | 基于气体爆炸动力学强冲击波爆炸等相关理论,根据瓦斯爆炸释放的能量,推导出爆炸后巷道内的超压、温度与至爆炸点距离的非线性计算公式,将计算值与试验值进行对比分析,得到瓦斯爆炸后冲击波的衰减规律,即爆炸后瞬间随传播距离的增加,巷道内超压和温度也都逐渐衰减。

| Abstract: | Based on the strong shock wave explosion of gas explosion dynamics and other related theory,according to the energy released from the gas explosion,a non-linear calculation formula was derived for the overpressure,temperature and the distance to the explosion location in the mine gateway after the mine explosion occurred.In comparison and analysis between the calculation value and the test value,the attenuation law of the shock wave after the mine gas explosion occurred was obtained.After the mine gas explosion occurred,with the propagation distance increased,both the overpressure and the temperature would steadily decreased. |
