Abstract：With the increasingly strict and standardized control of explosive materials, the number of malignant explosion cases across the country has been decreasing year by year. Criminal technicians of public security organs often feel great technical difficulty in calculating the amount of explosives when investigating the scene of condensed matter explosions.In order to solve the problems encountered in the exploration of such sites, ten commonly used formulas are sorted out in the order of gradually expanding from the central blast point to the peripheral site, and applied and analyzed with the help of actual cases. Then, systematic application ideas among different formulas are given to realize the combination of theory and practice.It has important practical significance for guiding the scene investigation of the explosion, especially the calculation of explosive quantity.
