Delay detonator and its use with explosive packaged boosters and cartridges

摘要

A nonelectric delay detonator for use with an explosive packaged booster or explosive cartridge wherein the detonator includes a detonation sensor which senses the detonation of a detonating cord, and a signal carrier consisting of an empty plastic or rubber tube having a diameter of 1.0-4.0 millimeters which transmits the detonation signal from the sensor to a non-electric delay blasting cap. One end of the tube signal carrier is inserted into the sensor while the opposite end of the tube is inserted into the cap whereby the tube is in open and direct communication with the sensor and cap.
