FIELD: blasting.
SUBSTANCE: intermediate detonator for borehole charges comprises a dome-shaped fixator, which retains and protects a case with installed initiation facilities, an explosive and a cover. The fixator design has openings for shock-wave tubes of detonator caps and stops for a charging hose, which makes it possible to perform mechanised charging of a well with automatic feed of the hose, and side elastic stops on the fixator, making it possible to easily align the direction of displacement of the intermediate detonator when redirecting into the well and preventing its reverse movement.
EFFECT: creation of a cheap, reliable, tight, safe, convenient intermediate detonator for well charges fixed in a well with the help of a structure element, which is driven by a pulse from a detonator cap.
