SUBSTANCE: means of blasting is made in the form of explosion-proof blank which consists of cartridge case with components of binary explosive located separately and combine to form liquid explosive before its application. Explosion of liquid explosive is initiated by electric pulse with the help of bridge with blasting wire or resistance bridge with igniting composition. According to one of invention versions, oxidizer and fuel are separated by membrane and located in strong cartridge case whose end has piston or made with soft walls capable of deformation.
