An operational method for evaluating the explosive characteristics and gas hazardousness of industrial explosives is presented. The distinctive feature of this approach is that the determination of the amount of toxic gases, detonation parameters and relative workability of explosives is carried out in a single experimental cycle, which makes it possible to comprehensively consider the peculiarities of the action of each explosive charge and objectively assess the level of its safety and effectiveness.

Around the cavity formed in the rock mass, under conditions of high rock pressure, there is a redistribution of the static stress field. Near the contour of the cavity there are three zones: stratification (squeezing), unloading and support pressure.
