FIELD: blasting operations.
SUBSTANCE: method consists in calculation of a value of a criterion showing increase of volume of explosive gases in comparison to initial charge volume based on fixation of quantity of destructed material in a metal marker plate at end influence on it of a tightly adjacent cylindrical charge of a test liquid explosive with initiation of explosion from the charge end that is opposite in relation to that adjacent to the plate in order to assess k coefficient of polytrope of explosion products as per an equation solved relative to k with further assessment of destructive properties of exploded charge as per the value of the above criterion that is calculated from the specified ratio.
EFFECT: improving assessment informativity and reliability.
