摘　　要：运用B-W法建立多孔粒状铵油炸药的爆炸反应方程式,依据盖斯定律计算定容爆热,加权法计算爆炸产物的摩尔定容热容,研究计算得出露天多孔粒状铵油炸药的比容为970.10L/kg、爆热为-3840.67kJ/kg、爆温2787K;并讨论分析了氧平衡值对多孔粒状铵油炸药热化学性能的影响情况。Based on B-W rule, the explosion reaction equation of porous granular ANFO explosive was predicted. The constant volume explosion heat of porous granular ANFO explosive was calculated based on Hess law and Specific Heat Capacity （SHC） of explosion products was calculated with the method of weighted averages. The results show that specific volume of porous granular ANFO explosive is 970. 10 L/ kg, constant volume explosion heat is --3840. 67 kJ/kg,and the explosion temperature is 2787 K. The influence of oxygen balance on the thermochemical properties of porous granular ANFO explosive were analyzed.
