Abstract
An explosion method includes selecting explosion place, drilling, arranging explosive in the deep hole, leading out by plastic detonating tube, connecting the plastic detonating tube to detonator by detonating fuse, and high-voltage pulse detonating by detonator. Its advantages are high safety etc.
Description
One, technical field
The present invention relates to a kind of blasting method, belong to the blasting technique field.
Two, background technology
At present, the general blasting method of people is to adopt fuse cord to connect blasting cap, by lighting fuse detonation.Adopt when expanding the explosion of kettle method in a large amount of mines, small towns, for saving the length of fuse cord, reduces cost, and makes igniting primer with the 30-50cm fuse cord, the igniting primer of lighting is thrown in the deep hole detonates." shotfiring safety rules " (HGB6722-86) 5.6.1 clause is violated in this blasting method, when deep hole expands kettle, forbids throwing igniting primer in the hole, when hole depth surpasses 5 meters, bans use of fuse cord to detonate; Violate the 3.2.14 clause simultaneously, after the length of fuse cord was answered the intact fuse cord of guarantee point, personnel can withdraw safety place to, but must not be shorter than 1.2 meters.So in expanding the big gun process, there is the hidden danger on the method.This fuse cord is disposable, and each explosion all needs to purchase again.And this explosion requires the operative employee that masterful technique and rich experience are arranged.
Three, summary of the invention
The technical problem to be solved in the present invention provides a kind of safety coefficient height, and is simple to operate, and the blasting method that cost of investment is low is big with danger coefficient in the solution prior art, shortcomings such as cost height.For this reason, the present invention takes following technical scheme:
A kind of blasting method may further comprise the steps:
(1) select fire point, explosive is placed in boring;
(2) igniting primer of being made by detonator is placed in the deep hole, by the outer 30-50cm of plastic detonating tube fairlead;
(3) plastic detonating tube is guided into the initiator of safety place with propagation of explosion;
(4) the high-voltage pulse spark percussion detonator that adopts initiator to send is ignited.
Described blasting method is applicable to chambering blasting.
Described detonator has a plurality of, is drawn by plastic detonating tube different in size respectively, and all plastic detonating tubes are guided into the initiator of safety place with a propagation of explosion, and described blasting method is applicable to the explosion of deep hole network.
A kind of blasting method of the present invention has following advantage:
1, the high-voltage pulse spark that adopts blaster to send is pulled the trigger the detonator of plastic detonating tube, makes personnel stand in safety place and implements to expand kettle, has improved degree of safety, has eliminated habitually and has operated against regulations.Prevent the generation of accident effectively; 2, improved operating efficiency, recorded, improved operating efficiency than common explosion and reached more than five times according to the testing ground; 3, simple to operate, common explosion must have masterful technique, has the rich experience employee to be competent at, and new blasting method general common big gun worker all can be competent at, and safe and reliable; 4, social benefit is obvious, promptly because safety has had assurance, impels employee's happy family life, enterprise's gain, social stability; 5, be widely used, not only be suitable for chambering blasting, also can be used for long distance explosions such as deep hole network, can save a large amount of detonators, reduce cost greatly; 6, small investment is purchased new initiator and is once invested, and can use for a long time, and it is humble to consume auxilliary material.
Four, description of drawings
Fig. 1 is the chambering blasting schematic diagram
Fig. 2 is a network explosion schematic diagram
Five, specific implementation method
Embodiment 1
The method of chambering blasting: 1, select fire point, boring 2 is placed explosive 1 wherein; 2, detonator 3 is made igniting primer and put into the hole, draw, the outer 30-50cm of plastic detonating tube fairlead by plastic detonating tube 4; 3, guide safety place into propagation of explosion lead-in wire 5, insert initiator 6; 4, adopt initiator to send the high-voltage pulse spark,, implement chambering blasting thereby make operating personnel stand in safety place by the detonator of percussion end 7 percussion plastic detonating tubes.
The method of deep hole network explosion: 1, select fire point, boring is placed explosive wherein, is netted arrangement; 2, detonator is made igniting primer respectively and put into the hole, outside plastic detonating tube different in size 4 fairleads; 3, guide the initiator 6 of safety place into a propagation of explosion lead-in wire 5; 4, adopt initiator 6 to send the high-voltage pulse spark,, thereby realize the explosion of deep hole network by the detonator of percussion end 7 percussion plastic detonating tubes.
Claims (3)
1, a kind of blasting method may further comprise the steps:
(1) select fire point, explosive is placed in boring;
(2) igniting primer of being made by detonator is placed in the deep hole, by the outer 30-50cm of plastic detonating tube fairlead;
(3) plastic detonating tube is guided into the initiator of safety place with propagation of explosion;
(4) the high-voltage pulse spark percussion detonator that adopts initiator to send is ignited.
2, a kind of blasting method as claimed in claim 1, it is characterized in that: described blasting method is applicable to chambering blasting.
3, a kind of blasting method as claimed in claim 1, it is characterized in that: described detonator has a plurality of, draw by plastic detonating tube different in size respectively, all plastic detonating tubes are guided into the initiator of safety place with a propagation of explosion, and described blasting method is applicable to the explosion of deep hole network.
