Abstract
The invention discloses the protective device and production method of a kind of jacket-type electric detonator, the metal sleeve and the rubber layer between electric detonator and metal sleeve that protective device includes the outside of electric detonator, electric detonator are interference fitted between three.Production method is can both to make metal sleeve and rubber sleeve respectively, and can also first making metal sleeve, interior apply forms rubber layer again, and finally three combines.Final electric detonator is in the protection of high-intensitive metal sleeve, effectively avoids blind big gun.The invention is used for blasting cap initiation technical field.
Description
Technical field
The present invention relates to blasting cap initiation technical fields, more particularly to the protective device and system of a kind of jacket-type electric detonator
Make method.
Background technique
Digital electric detonator initiation system technology has been mature on the whole, advance, reliability, practicability, flexibility and peace
Full property tool has great advantage, with the incomparable technical advantage of common electric cap and non-electric nonel tube detonator detonation system
And practical prospect.The electronic chip of intelligent Characteristics is installed in digital electric detonator, triple cryptoguards are used, according to " one
The overall control principle of one yard of pipe, Prior Control, subsequent retrospect ", flows to state administration authorities to industrial explosive materials
Control is carried out, even if occurring to lose, being stolen, criminal does not have password yet " have more than is needed, fry and do not ring ", is reduced to greatest extent
Explosive by criminal using harm society a possibility that, digital electric detonator initiation system technology will be complete in China
Face is universal.The initiation system is applied to surface blasting and demolition blasting, excellent, and safety, reliability, practicability and subtracts
Effect of shaking is very prominent.
But there is more prominent drawbacks in underground explosion engineering.This detonator is quick-fried in restricted clearance sinking and blasting
When broken, often there is phenomenon of partially miss-firing.Construction feature, extension mode of the generation for phenomenon of miss-firing mainly due to this kind of detonator
With caused by blasting environment.The extension and detonation of digital electric detonator be by its pipe chip and electronics network control, thunder
The chip and electronic circuit of pipe then no longer work, once being damaged to miss-fire.Digital electric detonator tunnels quick-fried for underground
When broken, subenvironment locating for blasting face position is different from surface blasting, and since tunnel section is smaller, and tunnel-surrounding hole is most
After detonate, after the keyhole and expanded hole charging explosion that detonate first, shock wave, seismic wave and the high temperature of evolution of generation of exploding
High pressure gas product is not easy to spread, and reflection and refraction action due to tunnel inner wall, not only strength retrogression is very slow, and at certain
Even there is the effect enhanced under the conditions of kind, thus the pressure field of some strength can be formed about in tunnel working face.The pressure
When the pressure of field is greater than the support strength of rear quick-fried detonator shell, the tube wall of hollow position in detonator pipe is flattened, and then destroys pipe
Interior chip and electronics network makes electric detonator fail and miss-fire without working again.
Underground explosion engineering generates phenomenon of partially miss-firing using digital electric detonator initiation system technology becomes underground always
The risk source more outstanding of one of bursting work, is miss-fired due to underground explosion and deals with difficulty and risk compared with dew
Its explosion is bigger, needs the technical problem that engineers and technicians are urgently to be resolved.
