Abstract

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).

Description

The invention relates to techniques for blasting.

Known detonating device containing an explosive chamber, an apolit, removable explosive gas mixture, ^{1 * 3} glow plug in it and tablets initiating explosive fl}.

Also known line in the form of a fillable explosive gas. With a mixture of’s tubes as an explosion conductor [2].

A disadvantage of the known devices is the lack of purging of the explosive chamber of the detonating device · an explosive gas mixture connected by a line to a source of detonating gas, which ensures the purity of the gas and increases the efficiency of the front of the detonating wave,

The purpose of the invention is to increase the reliability of ignition of the device.

This goal is achieved by the fact that in a detonating device containing an explosive chamber filled with an explosive gas mixture, a spark plug in it, an explosive line. in the form of sealed pipelines, a detonator capsule, including a jq sleeve with tablets of primary, slowing and initiating explosive compounds and plastic. a cavity in the detonator’s barrel, a cavity is formed between the initiating explosive charge in the sleeve and the plastic tube, in which leak-proof pipelines installed in the plastic tube exit, and this cavity communicates with the outlet channel formed by the second tube installed in the plastic tube or in the form holes located in the shell.

In FIG. 1-4. The proposed device is schematically shown.

Explosive chamber * '!, Filled with explosive gas mixture, containing a spark plug 2, is connected by an explosive line 3 with pressurized pipelines 4 And with capsule detonators A, B, C, D,' E.

. The detonator capsule (Fig. 3) contains a sleeve 5 with primary tablets 6, which slows down 7 and initiates 8 explosive compositions, with a plastic stopper 9 inserted into the sleeve of the sleeve, into which the pipeline of the explosive line passes. A cavity 10 is formed between the plastic plug and the primary composition through which the detonating gas is blown. The exhaust channel is made in the form of a second tube 11 mounted in a plastic plug. In FIG. 4 shows the exhaust channel in the detonator capsule, made in the form of an opening 12 in the sleeve.

The detonating device operates as follows.

The detonating gas formed in the explosive chamber moves along the line and is blown through the cavity of the detonator caps through the inlet and outlet pipelines, causing ignition and detonation of the group of detonator caps.

(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.
