摘　　要：运用B-W法确定膨化硝铵炸药的爆炸反应方程式,用盖斯定律计算定容爆热,用加权法计算爆炸产物的摩尔定容热容,研究计算得出露天膨化硝铵炸药、岩石膨化硝铵炸药、一级、二级煤矿许用膨化硝铵炸药的爆温依次为2 722 K2、771 K2、544 K和2 486 K。同时计算分析了复合油相中不同的石蜡与柴油的混合比例对岩石膨化硝铵炸药爆热、爆温数据的影响情况,计算结果表明复合油相组成的变化对岩石膨化硝铵炸药爆热、爆温的影响不明显。The explosion temperature of expanded ammonium nitrate explosives are calculated in this paper. The result shows that the explosion temperature of opencast expanded ammonium nitrate explosives, rock expanded ammo- nium nitrate explosives, class Ⅰ and Ⅱ coal mine permissible expanded ammonium nitrate explosives is 2 722 K, 2 771 K ,2 544 K ,2 486 K respectively. The explosion temperature of rock expanded ammonium nitrate explosives in assumed formula are calculated when the ratio of paraffin with diesel oil in composite fuel oil are different. According to the calculation results, it can be seen that the explosion heat and explosion temperature of rock expanded ammonium nitrate explosives increase weakly with the increasing of contents of paraffin in composite fuel oil.
