The beneficial effects of the utility model are: initiation system essence described in the utility model remains detonator and detonates, difference only is to utilize the point discharge of simple and easy percussion pin replaced detonating various detonators, primacord, percussion rifle, the special use of usefulness to excite pin and ignite first-classly, and its safety and reliability is still consistent with the performance that detonator detonates.Saved simultaneously blasting cost.In the place that gas and mineral dust explosion danger are arranged or environment, forbid to use.
Description of drawings
Fig. 1 is relay-type classification grouping of the present utility model bunch connection propagation of explosion mode structural representation.
Fig. 2 is 1 group large bunch connection of relay-type of the present utility model connection mode schematic diagram.
Number among the figure: 1, exploder; The 2nd, the exploder binding post; 3, shot firing cable; 4, twist shape detonator percussion pin; 5,6, the 1st grades of main detonation tubes and detonators; 7, the 2nd grade of detonation tube bunch connection bundle; 8, the 2nd grade of detonation tube detonator; 9, each big gun hole detonator and detonator; 10, waterproof insulation adhesive plaster; 11, Mao bamboo tube (specification Φ 40～Φ 60 * 200mm).
The specific embodiment
The utility model mainly comprises simple and easy percussion pin, exploder, detonator and the initiation net etc. of detonating that insulated conductor forms.
The described simple and easy percussion pin that detonates utilizes the point discharge principle, two close proximity electrode, when voltage high to a certain degree the time, nearest breakdown ionization of end air of two electrode distances, the temperature generation electric arc that sharply rises.Simultaneously, air is excited, and the air vibrations just produce shock wave.And with blue sparklet and " whip " sound.Under the safe current condition, because discharge energy is less, spark is limited in scope, and is not directly contacting in the situation of combustible and explosive articles, can not become the ignition source of combustible and explosive articles.Danger to the human body electric shock is also less, such as the electric igniter on the household gas range, and the electric igniter in the electronic lighter etc.
Detonator is the pipe that transmits detonation wave, if this electric spark is placed in the detonator pipe, electric spark will strongly compress the air dielectric in the tube chamber and form shock wave, thereby excite the explosive charge of detonator tube wall, this blast is along the inside pipe wall propagation of explosion, enter detonator to its end, and excite the Nonel detonator blast, drive again explosive charge; Or drive other detonator propagation of explosions, blasting cap detonation, explosive loading blast in the ignition big gun hole of final relay-type.
The described simple and easy percussion crown that detonates is as follows according to point discharge principle preparation method: with 1 section of mining loading wire of electric detonator as shot firing cable 3, be about 2 * 140mm, one end closes up to twist into and cuts flat after being about the long twist shape of 40mm, the tail end of detonator 5 (non-detonator 6 ends) also cuts flat, the twist shape payment to a porter is inserted in the detonator as detonator percussion pin 4, be wrapped with adhesive plaster.The other end is connected on the binding post 2 of exploder 1, also can detonate that adjunction one segment length is used for detonating at a distance less than the wire of 1000m between percussion pin 4 and the exploder 1 simple and easy.
The payment to a porter of electric cap is used BLV, wire nominal diameter 0.52mm, D.C. resistance 0.6～0.5 Ω/m, minimum insulation thickness 0.17mm for igniting.Generally can adopt explosion but do not have the remaining payment to a porter of the electric cap of broken skin.
Simple and easy detonating between percussion pin and the exploder also can be connected in series a segment length less than the shot firing cable (cable) of 1000m, is used for detonating at a distance.The material of shot firing cable, cross section need to decide according to the Blasting Control distance.In the 200m scope, can adopt cross section 2.5mm
2Copper core.
This is simple and easy, and the percussion pin that detonates can repeatedly use, and can use at least 200 times, namely can explosion at least 200 times.Cost is almost nil.
Adopt the mining electric cap detonating primer detonation of MFB-100 type, this exploder peak impulse voltage 1800V, energization action time 6ms.
Referring to Fig. 1, Fig. 2, detonator and detonator group's propagation of explosion and blasting network:
Detonator itself can not the direct initiation explosive, and it must be connected with detonator the purpose that just can reach detonating charge.
Nonel detonator and detonator group's propagation of explosion, adopt following two kinds of methods:
1, a relay-type classification grouping bunch connection propagation of explosion mode (being commonly called as " many handles that divide into groups are grabbed, and a detonator ") is seen Fig. 1. excite 10～15 detonators cluster bunch connection that divides into groups by a detonator.Detonator is made in order, be bundled into a branch ofly, tail end is also neat, oppositely inserts 1 detonating primer in the bundle.Finish detonating of whole section big gun hole.The detonating primer of every one-level should adopt same segment number.
Its propagation of explosion flow process is:
Exploder 1 → shot firing cable 3 → twist shape detonate percussion pin 4 → 1st grade main detonation tube and detonator 5,6 → 2nd grade grouping detonation tube and detonator 8 → respectively organize detonator and detonator 9.
2, adopt 1 group large bunch connection (being commonly called as " tackling all problems at once "), see Fig. 2.Namely the detonator of all detonators of working face is collected, made in order, be bundled into a branch ofly, tail end is also neat, inserts 1 detonating primer in the bundle.All are bundled into 1 bundle, the 1st grade of detonating primer of intrafascicular reverse insertion with working face.
When the detonator quantity of onepull during less than 15, directly will restraint parcel, tighten with electrician's plastic colloidal cloth.
When the detonator quantity of onepull during at 15～100, adopt in bunch connection bundle and fill out the paste explosive, overcoat Mao bamboo tube method.Mao bamboo tube 11 long 200mm internal diameters are 40～60mm.Mao bamboo tube is split into 2 half.Can adopt waste and old mao bamboon.
After the reverse insertion of detonating primer bunch connection is intrafascicular, in bunch connection bundle, fill out the emulsion of sticking with paste about 100g, gap between every detonator all to fill out stick with paste full, fill out and stick with paste length 200mm, after tying up looping with plastics waterproofing insulating tape 10, the skin of bunch connection bundle overlaps 2 half of Mao bamboo tubes 11 again, and is with explosive that filling in the cylinder is full, tight with the adhesive plaster looping.
Fill out the paste explosive in overcoat Mao bamboo tube 11 and bunch connection bundle, can strengthen a bunch detonation pressure that joins propagation of explosion in the bundle, and can make uniformly and stably propagation of explosion of bunch detonation wave that the connection bundle is interior.
Its propagation of explosion flow process is:
Exploder 1 → shot firing cable 3 → simple and easy percussion pin 4 → 1st grade main detonation tube and detonator 5,6 → each big gun hole detonator and the detonator 10 of detonating.
More than two kinds of methods, all can also in bundle, increase slotting 1 segment primacord by per 10～15 detonators.To strengthen the detonation pressure of propagation of explosion in bunch connection bundle.The every segment length 100～150mm of primacord.Primacord and has 1～2 near detonating primer in bunch intrafascicular even distribution of connection.
The utility model is not limited only to this example, and according to job site situation and specification requirement, its part technical indicator and parameter can make corresponding changes.
The utility model is applicable to peel off engineering in all kinds of ground earthwork evacuation engineering, surface mining, carries out blasting work without gas, the tunnel without mineral dust explosion danger, tunnel piercing, underground mining engineering.
