FIELD: earth or rock drilling, particularly means adapted to reduce mutual impact influence of explosives during well development and operation.
SUBSTANCE: method involves arranging one or more shock-absorbing members near one or more explosive doses, which prevent propagation of shock caused by detonation of the explosive doses. Shock-absorbing members include porous material, for instance gas-filled liquid or porous solid material, having 2%-9% porosity. Shock-proof screen may be arranged between detonating cord and explosive doses. Hollow charges may be placed in capsule.
EFFECT: increased reliability and capacity.
