为了评价典型工业炸药在空气中发生意外爆炸产生的灾害效应,利用非线性动力学软件AUTODYN,炸药产物选用JWL状态方程,分析1 kg铵油炸药、乳化炸药、2号岩石炸药在空气自由场中爆炸冲击波的传播特性和温度场分布情况,并与TNT炸药进行对比分析.计算结果表明,冲击波损害效应中,2号岩石炸药与TNT炸药爆炸产生的冲击波峰值相当,乳化炸药次之;温度灾害效应中,岩石炸药的温度峰值最高,铵油炸药温度峰值次之,乳化炸药温度峰值最低.为正确使用工业炸药和矿山安全提供了理论依据.

In order to evaluate the disaster effects generated by accidental explosion in air for typical industrial explosives,the spreading characteristics of air shock waves and temperature field of free-field explosion for 1kg ANFO,emulsion explosives and the 2nd rock explosives are investigated based on the nonlinear dynamics software AUTODYN and JWL state equation of explosion products,and are compared with TNT explosives.The calculated results show that in the temperature damage effect,the highest temperature is generated by rock explosives;the second is ANFO,followed by emulsion explosives.That disaster effect of temperature,the highest temperature is generated by the 2nd rock explosives and the second is ANFO,followed by the lowest temperature peak emulsion explosive.These conclusions provide theoretical basis for the correct use of industrial explosives and the safety of mines.
