Abstract
The utility model relates to mine explosion supplies, in particular to a length hole bottom exploder adopted in explosion of mining ores. A main detonation cartridge is arranged inside an integral plastic outer casing of the exploder, a blasting cap is arranged at a longitudinal one-third position in the middle of the main detonation cartridge, one end of the blasting cap is connected with a plastic detonating tube, the front end of the integral plastic outer casing of the exploder is hemispherical for guiding, guiding positioning sheets are arranged on the outer portion of the integral plastic outer casing of the exploder, and a blasting cap mounting opening is arranged between the two guiding positioning sheets at the front end of the integral plastic outer casing of the exploder. The length hole bottom exploder has the advantages that the large exploded ore block rate is greatly reduced as explosion is transmitted from a hole bottom to a hole opening when the exploder is mounted at the bottom of a mine exploded hole, thereby the exploder reduces the cost of secondary explosion and has the effect of improving production efficiency. The exploder is safe and convenient, improves production efficiency and reduces production cost.
Description
Technical field
The utility model relates to a kind of mine blasting category, the medium-length hole hole base initiation device that adopts when specifically relating to a kind of mining ore explosion.
Background technology
In underground mine was produced, during the exploitated ore explosion, institute adopted to go up dark blast hole in fan-shaped, generally takes hole base initiation mode in order to improve demolition effect.Traditional medium-length hole blasting is to fill explosive in blast hole, in order to guarantee at the bottom of reliable propagation of explosion is by aperture to hole 1～2 primacord to be housed, in the aperture with blasting cap initiation primacord and explosive, detonation propagation by aperture to hole at the bottom of; This detonation mode demolition effect is poor, ore boulder yield height, and production efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, the medium-length hole hole base initiation device that provide a kind of safe ready, enhance productivity, reduces production costs.
A kind of medium-length hole of the utility model hole base initiation device is achieved by following technical proposals: a kind of medium-length hole of the utility model hole base initiation device comprises plastic detonating tube, main volume medicine, guide-localization sheet, detonating capsule, detonator construction opening, priming device integral plastics shell, the detonator locating slot of detonating, described master detonate the volume medicine be arranged in the priming device integral plastics shell, detonating capsule is arranged on the main volume medicine central longitudinal of detonating to 1/3rd places, and detonating capsule one end is connected with plastic detonating tube; Described priming device integral plastics shell front end is the hemispherical guiding, and priming device integral plastics housing exterior is provided with the guide-localization sheet, has the detonator construction opening between two guide-localization sheets of priming device integral plastics shell front end.
A kind of medium-length hole of the utility model hole base initiation device has following beneficial effect compared with prior art: adorn the medium-length hole hole base initiation device that the priming device integral plastics shell of the web-like explosive that uses in the common production and nonel tube millisecond detonator constitutes in the utility model adopts one, handle assembly is installed on the bottom, blast hole hole in mine, utilize machinery again or manually the big gun hole is filled explosive, during explosion by at the bottom of the hole to the aperture propagation of explosion, thereby reach best demolition effect.Adopt this medium-length hole hole base initiation device,, reduced the secondary blasting cost, improved production efficiency owing to realized that the boulder yield of ore reduces greatly after the explosion by detonating to eating dishes without rice or wine at the bottom of the hole.The medium-length hole hole base initiation device that is a kind of safe ready, enhances productivity, reduces production costs.
Description of drawings
A kind of medium-length hole of the utility model hole base initiation device has following accompanying drawing:
Fig. 1 is a kind of medium-length hole of the utility model hole base initiation apparatus structure schematic diagram.
Wherein: 1, plastic detonating tube; 2, the main volume medicine that detonates; 3 guide-localization sheets; 4, nonel tube millisecond detonator; 5, detonator construction opening; 6, priming device integral plastics shell; 7, detonator locating slot.
The specific embodiment
Below in conjunction with drawings and Examples a kind of medium-length hole of the utility model hole base initiation device technique scheme is further described.
As shown in Figure 1, a kind of medium-length hole of the utility model hole base initiation device comprises plastic detonating tube 1, main volume medicine 2, guide-localization sheet 3, nonel tube millisecond detonator 4, detonator construction opening 5, priming device integral plastics shell 6, the detonator locating slot 7 of detonating, described master detonate the volume medicine 2 be arranged in the priming device integral plastics shell 6, nonel tube millisecond detonator 4 is arranged on main volume medicine 2 central longitudinal of detonating to 1/3rd places, and nonel tube millisecond detonator 4 one ends are connected with plastic detonating tube 1; Described priming device integral plastics shell 6 front ends are the hemispherical guiding, and priming device integral plastics shell 6 outer setting guide-localization sheets 3 have detonator construction opening 5 between two guide-localization sheets 3 of priming device integral plastics shell 6 front ends.
Described guide-localization sheet 3 is injected into one with priming device integral plastics shell 6, has detonator locating slot 7 on it.Described guide-localization sheet 3 is provided with 4 at least.
Embodiment 1.
The priming device integral plastics shell 6 of a kind of medium-length hole of the utility model hole base initiation device adopts the engineering plastics injection mo(u)lding with certain compression strength by shape shown in Figure 1, in the main volume medicine 2 that detonates pack into priming device integral plastics shell 6 from the open rearward end of priming device integral plastics shell 6, plastic detonating tube 1 connects with non-conductive booster millisecond detonator 4 front ends, non-conductive booster millisecond detonator 4 is placed and made it at main volume medicine 1/2nd three place and parallel with the main volume medicine 2 that detonates of detonating from the detonator construction opening 5 of priming device integral plastics shell 6 front ends priming device integral plastics shell 6 backs that tilt to pack into, plastic detonating tube is drawn and is connected in the detonator locating slot 7 on the guide-localization sheet 3 of priming device integral plastics shell 6 rear ends fixing from detonator construction opening 5, guide the rear end of priming device integral plastics shell 6 into.
The medium-length hole hole base initiation device that assembles is encased in bottom, medium-length hole hole by the hemispherical guiding of priming device integral plastics shell 6 front ends towards the blast hole that digs in advance, 4 flexible guiding spacers 3 that priming device integral plastics shell 6 two ends and middle part are provided with are convenient to the fixedly effect of priming device, make the priming device can be from the hole landing of medium-length hole big gun, the sphere of priming device front end also can play the effect of the guiding when priming device is installed.After priming device is put into the medium-length hole blasting hole, plastic detonating tube 1 is drawn out to outside the blast hole, utilizes machinery again or manually blast hole is filled explosive.During explosion explosive by the hole at the bottom of to the aperture propagation of explosion, can reach best demolition effect.The utility model adopts medium-length hole hole base initiation, realized by at the bottom of the hole to direct priming, the boulder yield of ore reduces greatly after the explosion, has reduced the secondary blasting cost, can effectively enhance productivity.
