FIELD: blasting operations in mining, petroleum-gas industries and civil engineering. SUBSTANCE: the detonating device casing accommodates an igniting element, intermediate shell, initiating and initial charges. The initiating charge is additionally placed in a shell, partially or completely positioned in the intermediate shell, having a hole on the side of the igniting element. The additional shell on the side of the initial charge has a lesser thickness as compared with the remaining part or an open end. A partition, partially or completely placed inside the additional shell, is installed between the initiating and initial charges. The partition cross-section area equals the cross-section area of the initiating charge. The partition is made in the form of a cup, whose bottom faces the initial charge. Placed between the igniting element and initiating charge are the retarding and/or ignition compound. EFFECT: simplified manufacturing methods. 7 cl, 1 dwg |
