Abstract
Mining blasting cartridge, comprise segmented plastic tube, pre-shrink rock pillar, explosive, rectangular bamboo chip, shutoff stemming, detonator and primacord, segmented plastic tube is by being threaded and forming before and after at least two sections of bodys, in the tube wall of every section of body, there is cavity, the bottom lock of latter end body and its inner bottom part have pre-shrink rock pillar, the top open part of first section of body arranges shutoff stemming and seals, detonator, primacord passes shutoff stemming and stretches into segmented inside of plastic tubes from outside, explosive is equidistantly fixed on rectangular bamboo chip, in the segmented plastic tube of rectangular bamboo chip between pre-shrink rock pillar and shutoff stemming.This blasting cartridge can regulate body quantity according to actual conditions; to change at any time blasting cartridge length; in blasting process; water in body or other nontoxicly do not fire a large amount of explosion particles or the dust that not quick-fried liquid can produce in the time of explosion and are combined; the Dust Capacity that reduction explosion produces, the impulsive force of buffer shooting particle also reduce noise of blasting, guarantee construction safety.
Description
Technical field
The utility model relates to a kind of mining blasting cartridge, belongs to field of mining.
Background technology
Conventionally, in field of mining, conventional blasting cartridge carries out explosion, but the length of traditional blasting cartridge is definite value, cannot meet the explosion requirement of different mining environments, application is inconvenient, and in the time of explosion, easily produce a large amount of explosion particles, on the one hand, noise of blasting is large and impulsive force is strong, when construction, there is potential safety hazard, on the other hand, a large amount of particles and dust can affect surrounding environment, and these problems are not also solved well at present.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of reasonable in design is provided, can changes according to actual needs length and effectively reduces the mining blasting cartridge of noise of blasting, dust, guaranteed construction safety.
Mining blasting cartridge described in the utility model, comprise segmented plastic tube, pre-shrink rock pillar, explosive, rectangular bamboo chip, shutoff stemming, detonator and primacord, segmented plastic tube is by being threaded and forming before and after at least two sections of bodys, in the tube wall of every section of body, there is cavity, the bottom lock of latter end body and its inner bottom part have pre-shrink rock pillar, the top open part of first section of body arranges shutoff stemming and seals, detonator, primacord passes shutoff stemming and stretches into segmented inside of plastic tubes from outside, explosive is equidistantly fixed on rectangular bamboo chip, in the segmented plastic tube of rectangular bamboo chip between pre-shrink rock pillar and shutoff stemming.
Operation principle and process:
Before explosion, the first increase of the actual conditions according to explosion or minimizing body quantity change the total length of blasting cartridge at any time, to meet the explosion requirement of different mining environments, nontoxic do not fire not quick-fried liquid with syringe or other instruments to injected water in the tube wall cavity of each section of body or other afterwards, finally pass through detonator, primacord is by the explosive initiation of segmented inside of plastic tubes, realize explosion, in blasting process, a large amount of explosion particles or dust that water or liquid can produce in the time of explosion are combined, both reduced the Dust Capacity that explosion produces, impulsive force that again can buffer shooting particle, reduce noise of blasting, guaranteed construction safety simultaneously.
The beneficial effect that the utility model compared with prior art had is:
This blasting cartridge reasonable in design, by adopting segmented plastic tube, can increase or reduce body quantity and change at any time according to the actual conditions of explosion the total length of blasting cartridge, to meet the explosion requirement of different mining environments, applied range and easy to operate, and can guarantee demolition effect; In blasting process; the water injecting in the tube wall cavity of each section of body or other nontoxicly do not fire a large amount of explosion particles or the dust that not quick-fried liquid can produce in the time of explosion and are combined; both reduced the Dust Capacity that explosion produces; impulsive force that again can buffer shooting particle; reduce noise of blasting, can guarantee construction safety simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, latter end body; 2, cavity; 3, pre-shrink rock pillar; 4, explosive; 5, rectangular bamboo chip; 6, stage casing body; 7, first section of body; 8, shutoff stemming; 9, detonator; 10, primacord.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, mining comprises segmented plastic tube with blasting cartridge, pre-shrink rock pillar 3, explosive 4, rectangular bamboo chip 5, shutoff stemming 8, detonator 9 and primacord 10, segmented plastic tube is made up of at least two sections of bodys, in the tube wall of every section of body, there is cavity 2, in the present embodiment, adopt three sections of bodys, first section of body 7, stage casing body 6, end body 1 front and back are threaded and form, the bottom lock of latter end body 1 and its inner bottom part have pre-shrink rock pillar 3, the top open part of first section of body 7 arranges shutoff stemming 8 and seals, detonator 9, primacord 10 passes shutoff stemming 8 and stretches into segmented inside of plastic tubes from outside, explosive 4 is equidistantly fixed on rectangular bamboo chip 5, in the segmented plastic tube of rectangular bamboo chip 5 between pre-shrink rock pillar 3 and shutoff stemming 8.
Before explosion, the first increase of the actual conditions according to explosion or minimizing body quantity change the total length of blasting cartridge at any time, to meet the explosion requirement of different mining environments, nontoxic do not fire not quick-fried liquid with syringe or other instruments to the interior injected water of tube wall cavity 2 of each section of body or other afterwards, finally by detonator 9, primacord 10 is ignited the explosive of segmented inside of plastic tubes 4, realize explosion, in blasting process, a large amount of explosion particles or dust that water or liquid can produce in the time of explosion are combined, both reduced the Dust Capacity that explosion produces, impulsive force that again can buffer shooting particle, reduce noise of blasting, guaranteed construction safety simultaneously.
