The mainstream of conventional blasting methods was to use dynamite and an electric detonator, but from the viewpoint of cost and safety, in recent years, combinations of explosives such as ammonium nitrate explosives and slurry explosives and electric detonators have been used instead of dynamite. is becoming mainstream. All of these blasting methods required detonation and detonation using a detonator-equipped explosive package (also called a parent die) made of dynamite or a detonator-detonating slurry explosive and an electric detonator.

However, when making this explosive package with a detonator, the electric detonator is inserted into the explosive, and in order to prevent the electric detonator from falling off the cartridge, the leg wires of the electric detonator are tied around the cartridge, and the legs are tied together. This required complicated work such as fixing the wire and the medicine package with tape. For this reason, the process of making explosive cartridges with detonators took a lot of time and was extremely dangerous. In addition, with conventional electric detonators, when a detonating slurry explosive is used in an explosive package with a detonator, the electric detonator may be compressed and deformed by the impact from the adjacent hole, resulting in a non-explosion or half-explosion. There was a problem from a security perspective.

The present invention has been made to solve these drawbacks, and if blasting is performed using a detonator consisting of an electric detonator and a detonator tube further pressurized with explosives fitted on the outside, it will be more effective than conventional blasting. It was completed after discovering that it could replace the necessary explosive cartridge with detonator.

As described above, according to the detonator of the present invention, it is no longer necessary to create an explosive package with a detonator, which conventionally required a lot of time to create and was considered to be extremely dangerous. shortened to a large width,
And the opportunity for danger has disappeared. It has also become possible to uniformly detonate a wide variety of explosives, from insensitive explosives such as ammonium nitrate explosives and slurry explosives to sensitive explosives such as dynamite. Furthermore, since the detonator according to the present invention has a double tube structure, its impact resistance against the impact caused by the blasting of the previous stage during stage blasting is also much improved compared to conventional explosive packages with detonators. Furthermore, manufacturing according to the present invention is simple, as only the embolization manufacturing process of the conventional electric detonator manufacturing process needs to be changed, and the other processes can be left as they are. Therefore, the detonator of the present invention is extremely useful.
