FIELD: blasting operations.
SUBSTANCE: method of creation of directed explosion comprises burst of initial sources and creation of a shock wave. As initial sources an explosive is used, formed as spirals with varying pitch and the winding radius. The spirals are located in the space as a fan, forming a circular straight cone in which the apex angle Θ is connected to the speeds of blast wave Vbw and shock wave Vsw with the ratio: Θ=arssos (Vbw/Vsw), followed by blasting of the cone from the apex.
EFFECT: creation of a more effective method of direction of explosion.
