Abstract：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-3777.00 kJ· kg-1, the explosion temperature is 2771 K, Specific Volume is 965.15 L· 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-2312.09 kJ· kg-1 respectively, the explosion temperature are 2257 K and 2127K respectively, Specific Volume are 842.26 L· kg-1 and 817.06L· kg-1 respectively.
