摘　　要：用加速量热仪研究了岩石乳化炸药的绝热分解过程,得到了绝热分解温度与压力随时间的变化、自加热速率与分解压力随温度的变化曲线以及压力转化分数随时间的变化曲线,并分析了热分解过程,计算了分解动力学参数表观活化能和指前因子,据此分析了岩石乳化炸药的安全性,表明乳化炸药具有良好的热稳定性。The adiabatic decomposition of rock emulsion explosive has been studied by an accelerating rate calorimeter. The curves of thermal decomposition temperature and pressure versus time, selfheating rate and pressure versus temperature and pressure conversion rate versus time were obtained. The kinetic parameters such as apparent activation energy and preexponential factor were calculated. The decomposition history and safety of emulsion explosive were analysed. It was indicated that the rock emulsion explosive possesses better stability and safety.
