FIELD: blasting.
SUBSTANCE: sheet secondary aluminium is additionally introduced into compositions and charges of explosives. In process of cartridging an explosive in a polymer shell is placed into a shell made of sheet secondary aluminium. In process of formation of a well charge in process of charging a shell made of sheet secondary aluminium with an explosive, the secondary aluminium in the form of a device for development of an axial cavity in a charge is installed inside a composition of an explosive.
EFFECT: higher efficiency of a charge.
