INITIATING UNIT (MODIFICATIONS), SLIDING DEVICE (MODIFICATIONS), METHOD FOR ARRANGEMENT OF DETONATOR INLET AND METHOD FOR LOCATION OF DETONATOR INLET (MODIFICATIONS)

摘要

FIELD: blasting operations. SUBSTANCE: for transmission of non-electric initiating signals from the detonating cord of the master signal lines to the fuzes of the receiving line transmitting the signal the transmitting line is positioned in configuration of improved signal communication with the master line. The receiving line may form the detonator lead-in. The configuration of improved transmission of signals between the lead-in and detonating cord may be formed by arrangement of the input line with at least partially enveloping contact with the detonating cord or with a multiple adjoining contact with the detonating cord. Configuration of improved transmission of signals may be also attained for a detonator having at least two input lines with an adjoining contact with the detonating cord. The sliding device is designed for improvement of contact between the detonator lead-in and the acting cord. The sliding device has a holder for keeping the detonator and a supporting clamp with a through hole for the detonating cord. The means for holding the lead-in in the supporting clamp arranges the lead-in in the position of improved signal communication with the detonating cord, which may run through the through hole. EFFECT: enhanced safety. 28 cl, 18 dwg
