Abstract
The utility model provides a blasting charge structure belongs to the demolition unit field. This blasting charge structure, including the big gun hole, big gun hole drill way has clogs, still includes bracing piece and a plurality of medicated roll, a plurality of medicated roll along bracing piece length direction spaced on the predetermined recess in big gun hole, still including lead explode the detonator and with lead the explosive fuse that explodes the detonator and link to each other, the explosive fuse twines on the bracing piece, lead to explode the detonator and establish at the bracing piece tip, and the bracing piece to push the big gun with a plurality of medicated roll downthehole to the messenger leads explodes on the detonator arranges big gun hole hole bottom in, and the explosive fuse passes to clog and draws forth from big gun hole drill way. The recess in big gun hole can make that medicated roll is firm to be put on the big gun hole, and the position is difficult to change, and the device has still solved the bold that present blasting brought and has produced more problem.
Description
Technical field
This utility model belongs to blasting technique field, relates to a kind of blast charging structure.
Background technology
Traditional charge constitution is bottom powder charge in big gun hole, and top is clogged by wadding, and explosive concentrates on step bottom excessively, makes in the middle part of step, top can not be subject to the direct effect of explosive.When step top exists hard rock, adopting traditional charge constitution, step top Large fragmentation rate is high, and demolition effect is undesirable.
Accordingly, it would be desirable to improve traditional charge constitution, strengthen crushing step top rock, reduce oversized fragment rate, improve demolition effect.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that a kind of better blast charging structure of demolition effect.
The purpose of this utility model can be realized by following technical proposal: a kind of blast charging structure, including big gun hole, aperture, big gun hole has filling, it is characterized in that: also include support bar and some powder sticks, described some powder sticks are placed on shrinkage pool along big gun hole length direction, also include leading quick-fried detonator and with lead the primacord that quick-fried detonator is connected, described primacord is wrapped on support bar, lead quick-fried detonator and be located at support bar end, and some powder sticks are pushed in described big gun hole by described support bar, and make described quick-fried detonator of leading be placed at the bottom of hole, big gun hole, described primacord is drawn through filling from aperture, big gun hole.
Explosion is from the powder stick at the bottom of hole, big gun hole, and after detonating, detonation wave starts to propagate, and meanwhile, the high temperature and high pressure gas that explosive reaction is formed expands rapidly, drives all the other powder stick explosions, therefore can reduce the bulk of overall generation, thus reducing energy consumption.
In above-mentioned a kind of blast charging structure, described support bar is bamboo cane or batten.
Therefore the overall fragmentation of explosion back support rod energy, it is prevented that support bar produces secondary damage.
In above-mentioned a kind of blast charging structure, described shrinkage pool lower surface is plane.
In above-mentioned a kind of blast charging structure, described powder stick is emulsion, and described quick-fried detonator of leading is non-electric shock conducting tube detonator.
In above-mentioned a kind of blast charging structure, described big gun hole includes big gun hole, left hole and big gun hole, right hole, and big gun hole includes pre-ceasma, keyhole, cut spreader hole, bottom plate hole, via hole and light blast hole successively by ignition order.
Compared with prior art, this utility model has the advantage that
Explosion is from the powder stick at the bottom of hole, big gun hole, and after detonating, detonation wave starts to propagate, and meanwhile, the high temperature and high pressure gas that explosive reaction is formed expands rapidly, drives all the other powder stick explosions, therefore can reduce the bulk of overall generation, thus reducing energy consumption；The groove in big gun hole can make powder stick firmly be placed on big gun hole, and change is less likely to occur in position.
Accompanying drawing explanation
Fig. 1 is this blast charging architecture schematic diagram.
In figure,
1, big gun hole；11, shrinkage pool；2, filling；3, powder stick；4, support bar；5, quick-fried detonator is led；6, primacord.
Detailed description of the invention
The following is specific embodiment of the utility model and in conjunction with accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
As shown in Figure 1, this utility model one blast charging structure, including big gun hole 1, aperture, big gun hole 1 has filling 2, also include support bar 4 and some powder sticks 3, some powder sticks 3 are tied up on support bar 4 along support bar 4 length direction interval, also include leading quick-fried detonator 5 and with lead the primacord 6 that quick-fried detonator 5 is connected, primacord 6 is wrapped on support bar 4, lead quick-fried detonator 5 and be located at support bar 4 end, and some powder sticks 3 are pushed in big gun hole 1 by support bar 4, and making to lead quick-fried detonator 5 and be placed at the bottom of hole, big gun hole 1, primacord 6 is drawn through filling 2 from aperture, big gun hole 1.
Further, support bar 4 is bamboo cane or batten.Powder stick 3 is emulsion, and leading quick-fried detonator 5 is non-electric shock conducting tube detonator.Big gun hole 1 includes big gun hole, left hole 1 and big gun hole, right hole 1, and big gun hole 1 includes pre-ceasma, keyhole, cut spreader hole, bottom plate hole, via hole and light blast hole successively by ignition order.
Explosion is from the powder stick 3 at the bottom of hole, big gun hole 1, and after detonating, detonation wave starts to propagate, and meanwhile, the high temperature and high pressure gas that explosive reaction is formed expands rapidly, drives all the other powder stick 3 explosions, therefore can reduce the bulk of overall generation, thus reducing energy consumption.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount the scope that appended claims is defined.
Although more employing big gun hole 1, filling 2, powder stick 3, support bar 4 herein, leading the terms such as quick-fried detonator 5, primacord 6, but it is not precluded from using the probability of other term.These terms are used to be only used to describe and explain essence of the present utility model more easily；It is all contrary with this utility model spirit for being construed as any additional restriction.
