    1449560 Blasting caps HERCULES Inc 19 Dec 1974 [20 Dec 1973] 54906/74 Heading F3A [Also in Division E1] A blasting cap comprises an initiator charge 17 ignitable in response to the thermal detonation energy of an explosive gas mixture that is conveyed into a space 18, through a conduit 19, and thenignited. A conduit 21, or an opening in the sidewall of the cap, permits the space 18 to be purged of gases other than the explosive gas. A plurality of the caps can be connected in series so as to have a common gas flow or they can be individually connected to a supply manifold. The caps are fired by igniting the gas upstream of the first cap (see Division E1).

    (54) BACKGROUND OF THE INVENTION The invention relates to blasting techniques. A detonating device is known which contains an explosive chamber filled with an explosive gas mixture, a spark-plug therein and tablets of an initiating explosive I. The main line is also known as a filled explosive gas. Mixture tube as a conductor of the explosion 2. . -. A disadvantage of the known devices is the lack of blowing the explosive chamber of the detonating device with an explosive gas mixture, connected to the source of the detonating gas, which ensures the purity of the gas and increases the efficiency of the detonating wave front. The purpose of the invention is to improve the reliability of the ignition device. This goal is achieved by the fact that in a detonating device containing an explosive chamber filled with an explosive gas mixture, a firing candle in it, an explosive line in the form of sealed piping, a detonator capsule including a liner with tablets of primary, retarding and initiating compositions. explosives and plastic. There is a cavity in the barrel of the detonator, between the opening of the explosive charge and the plastic plug, a cavity is formed in which the sealed pipelines installed in the plastic tube exit and the cavity is connected to the outlet tube formed by the second tube installed in the plastic tube in the form of a hole located in the shell. FIG. 1-4. schematically shows the proposed device. An explosion chamber filled with an explosive gas mixture containing a spark-plug 2 is connected by a blast line 3 to hermetically sealed pipelines 4 and to capsule detonators A, B, C, D, E, the Detonator cap (Fig. 3) contains a sleeve 5 with tablets primary 6, retarding 7, and initiating 8 components, explosives, with a plastic stopper 9 inserted into the sleeve tube, into which the main line has passed. Between the plastic stopper and the primary composition, a cavity 10 is formed. The detonating gas is blown through it. The exhaust channel is made in the form of a second tube 11 installed in a plastic stopper. FIG. 4 shows the outlet channel in the detonator cap made in the form of an opening 12 in the sleeve. The detonating device operates in the following manner. The detonating gas formed in the explosion chamber, moving along the main line, is blown through the cavities of the detonator caps through the inlet and exhaust pipes, causing the group of condenser-detonators to ignite and detonate. Claim 1. Detonating device containing an explosive chamber filled with an explosive gas mixture, per. Candle, an explosive line in it in the form of sealed pipelines, a detonator capsule including a cartridge case with tablets of primary slowing-down and initiating compositions of explosives and a plastic plug in a detonator capsule, characterized in that / with A cavity is formed between the initiating charge of the explosives located in the sleeve and the plastic plug, into which the tight piping is installed in the plastic plug, with the specified This is connected to an outlet channel formed by a second tube installed in a plastic plug. . 2. Device .1, about tl and h a.yu shch it with the fact that the exhaust channel is made in the form of a hole located in the sleeve. Sources of information received.
