摘　　要：运用B-W法确定改性铵油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,研究计算了露天型改性铵油炸药、岩石型改性铵油炸药、抗水岩石型改性铵油炸药爆热为-3777.00 kJ·kg-1、爆温为2771 K,比容为965.15 L·kg-1,一级煤矿许用改性铵油炸药、二级煤矿许用改性铵油炸药的爆热分别为-2567.69kJ·kg-1、-2312.09 kJ·kg-1,爆温依次为2257 K、2127K,比容为842.26 L·kg-1、817.06L·kg-1。Based on B-W rule the explosion reaction equation of modified ANFO explosive were established. The constant volume explosion heat of modified ANFO explosive were calculated based on Hess law, and Specific Heat Capacity （SHC） of explosion products were calculated with the method of weighted averages. The result shows that constant volume explosion heat of opencast modified ANFO explosive, rock modified ANFO explosive and water resistant rock modified ANFO explosive is -3777.00kJ·kg^-1, the explosion temperature is 2771K, Specific Volume is 965.15L·kg^-1, that constant volume explosion heat of the class I and Ⅱ coal mine permissible modified ANFO explosive are -2567.69kJ·kg^-1 and -2312.09kJ·kg^-1 respectively, the explosion temperature are 2257 K and 2127K respectively, Specific Volume are 842.26L·kg^-1 and 817.06L·kg^-1 respectively.
