Abstract
The utility model discloses a be applicable to mine medium -length hole hole bottom initiating device, its characterized in that: include detonating bullet and the detonator of being connected with detonating bullet, detonating bullet includes the polyethylene shell and sets up granule ammonium nitrate fuel oil explosive in bulk and the on -electrical millisecond detonator in the polyethylene shell that on -electrical millisecond detonator connects detonator, the mining detonating ware of detonator connection. The utility model relates to a rationally, safety coefficient is high, and is with low costs, and the time limit for a project is short, greatly reduced the cost of blasting.
Description
Technical field
The utility model belongs to one and is applicable to mine length hole bottom exploder.
Background technology
At present, in metallurgical underground mine, need deep hole mining, need to adopt blasting mining.But blasting mining needs a large amount of manual labor, and the cost of explosive is very high, and operating procedure is very complicated, inefficiency.
For reducing medium-length hole blasting mining cost, need a kind of reasonable in design, economical, safe, be simply applicable to mine length hole bottom exploder.
Utility model content
The technical problems to be solved in the utility model overcomes above-mentioned defect, provide a kind of reasonable in design, economical, safe, be simply applicable to mine length hole bottom exploder.
For solving the problem, the technical scheme that the utility model adopts is:
Be applicable to mine length hole bottom exploder, it is characterized in that: the detonator comprising priming bomb and be connected with priming bomb; Described priming bomb comprises polyethylene sheath and the bulk granular ammonium nitrate-fuel oil mixture that is arranged in polyethylene sheath and non-electric ms detonator, and non-electric ms detonator connects detonator, detonator connecting mine initiator.
As a kind of technical scheme of optimization, described polyethylene sheath comprises and is provided with shell cap, cap and body from top to bottom; Described shell cap, cap and body are fixedly connected sequentially; Described cap with body is provided with the guide groove be communicated with.
Owing to have employed technique scheme, compared with prior art, the utility model is reasonable in design, and security system is high, and cost is low, and the duration is short, greatly reduces the cost explosion.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the using state figure of Fig. 1.
Detailed description of the invention
Embodiment:
As shown in Figure 1 and Figure 2, be applicable to mine length hole bottom exploder, and play the deep hole 4 installing demolition set effect and match.The described detonator 7 being applicable to mine length hole bottom exploder and comprising priming bomb and be connected with priming bomb.Described priming bomb comprises polyethylene sheath and the bulk granular ammonium nitrate-fuel oil mixture 5 that is arranged in polyethylene sheath and non-electric ms detonator 6, and non-electric ms detonator 6 connects detonator 7, detonator 7 connecting mine initiator.
In the present embodiment, described polyethylene sheath comprises and is provided with shell cap 1, cap 2 and body 3 from top to bottom.Described shell cap 1, cap 2 and body 3 are fixedly connected sequentially.Described cap 2 is provided with on body 3 guide groove be communicated with.
Detailed description of the invention of the present utility model is:
1) blasted material prepares:
Bulk granular ammonium nitrate-fuel oil mixture, the powder charge of BQF-100 explosive loader, non-electric ms detonator (20m payment to a porter, specially process), polyethylene detonate shell case priming bomb, plastic detonating tube, mining initiator.
2) shell case that detonates is processed:
Priming bomb adopt polyethylene detonate shell case and bulk granular ammonium nitrate-fuel oil mixture processing, shell case body is filled sticky particle ammonium nitrate-fuel oil mixture in bulk, and compacting, millisecond on-electric detonator is passed through outer body groove plug inside body, cover cap, press tight lid, adopt plastic insulation adhesive plaster detonator payment to a porter to be pressed in inside outer body groove, must guard against when twining adhesive plaster and shell has all been twined, leave certain distance (10mm ~ 20mm).
3) powder charge:
First the manufactured shell case powder charge pipe that detonates (2 cun, antistatic high-voltage tube) is delivered at the bottom of hole, open high-pressure blast explosive to be blown to big gun hole, only (mark before powder charge pipe) to design attitude, plug-hole is firmly grasped after completing, prevent explosive from trickling down, the like, install the row wanting explosion.In the process of conveying priming bomb, necessarily prevent powder charge pipe to dawdle payment to a porter.
4) line detonates:
The detonator payment to a porter that big gun hole is drawn is intersected mutually binding together, adopt plastic detonating tube to cause initiator place, can detonate after waiting personnel all to withdraw safety zone.
The utility model is reasonable in design, and security system is high, and cost is low, and the duration is short, greatly reduces the cost explosion.
The utility model is not limited to above-mentioned preferred embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
