Abstract
The invention discloses a kind of blasthole pulse infusion shot firing methods, including stemming, Nonel detonator, powder charge upper layer and powder charge lower layer, the stemming is located at blasthole top layer, the horizontal decoupling charge structure of " water bag-emulsion-water bag " is powder charge upper layer, it is emulsion and water bag below the powder charge upper layer, the vertical coupled charge constitution of " water bag-emulsion-water bag " is powder charge lower layer, and the emulsion is detonated with Nonel detonator.Emulsion at powder charge lower layer is first initiated, and the present invention solves that water mist existing for existing method is small, and dust-laying effect is general；The problems such as water mist direction is uncontrollable, and secondary dust removing effect is poor has reliable theoretical foundation, easy to operate.
Description
Method field
The present invention relates to blasting engineering method field, specifically a kind of blasthole pulse infusion shot firing method.
Background method
With the development of social progress and urban construction, China's Old City building demolition amount increases year by year, urban architecture
Object is removed most using blasting method.There are blasting energies to distribute non-uniform problem for existing blasting method, and part rock is not
It can be completely broken, generate a large amount of dust, pollute environment.
Invention content
A kind of blasthole pulse infusion shot firing method provided by the invention can solve the problems, such as that blasting energy distribution is uneven, can have
Effect depositing dust, absorption are harmful to toxic gas, reduce concussion of blasting and reduce the excessive dust generated because base charge energy is excessive.
To achieve the above object, the present invention provides following method method：A kind of blasthole pulse infusion shot firing method, including stemming,
Nonel detonator, powder charge upper layer and powder charge lower layer, the stemming are located at blasthole top layer, be emulsion below the stemming with
The horizontal decoupling charge structure of water bag, " water bag-emulsion-water bag " is powder charge upper layer, the powder charge upper layer lower section
Vertical coupled charge constitution for emulsion and water bag, " water bag-emulsion-water bag " is powder charge lower layer, the breast
Change explosive to detonate with Nonel detonator.
Preferably, the powder charge upper layer uses the horizontal Uncoincided charge method of water bag-emulsion-water bag, aqueous medium pressure
Contracting coefficient is small (but having certain compressibility), and density ratio air is more than 800 times big, is good transmission medium.Using emulsion-
Water bag Uncoincided charge method, has effectively been sustained energy, reduces the generation of powder, simultaneously because explosive-water-rock wave resistance
Anti- mismatch generates wave absorption and makees, and dissipated part Wave energy.The addition of aqueous medium, can be wet after explosion is crushed and forms water mist
Profit sticks mountain flour, promotes dust settling.
Preferably, the powder charge lower layer is that water bag-vertical coupled charge constitution of emulsion-water bag plays reduction vibrations
Excessive and the excessive dust of generation the effect with reduction base charge energy.
Preferably, the powder charge lower layer is first detonated by Nonel detonator, is detonated by Nonel detonator behind the powder charge upper layer,
The two is divided into 25ms between the burst time.
The present invention provides blasthole pulse infusion shot firing method compared with the conventional method, and advantage is embodied in：Powder charge upper layer is
Decoupling charge structure plays slow releasing function to explosive energy；The wave impedance of explosive-water-rock mismatches the fluctuation that dissipated
Energy；The addition of aqueous medium forms water mist when explosion is broken, can soak and stick attached mountain flour, promotes dust settling；It uses
The water filling of delay charge structure, water bag II and water bag III can be sufficiently formed water mist, and dust-laying effect is more preferably.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, is carried out to the method scheme in the embodiment of the present invention clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, this field commonsense method personnel are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Refering to fig. 1, a kind of blasthole pulse infusion shot firing method provided by the invention：There are an a diameter of 70mm, length in country rock center
For the blasthole of 120cm, blasthole top layer is stemming, and the level for being water bag I- emulsion I- water bags I below stemming does not couple dress
Medicine structure, emulsion I are connected with Nonel detonator I, are water bag II- emulsion II- water bags III below emulsion I
Vertical coupled charge constitution, emulsion II is connected with Nonel detonator II, and Nonel detonator I and Nonel detonator II are worn
It is protruding to cross stemming.
Described in above-described embodiment, exploded using Nonel detonator II detonations emulsion II, emulsion II,
Water bag III and water bag II ruptures, the propagation medium of the water of water bag III as blasting energy, it is excessive to reduce base charge energy
And the excessive dust generated, the water of water bag II form water mist, and then dust is formed by emulsion II broken rocks and is adsorbed.
After Nonel detonator II detonations 25ms, Nonel detonator I detonates, to the emulsion I that detonates.Emulsion I occurs
The water of explosion, water bag I ruptures, water bag I forms water mist since decoupling charge structure, blasting energy are sustained, and avoids rock
Overcrushing；The wave impedance of emulsion-water-rock, which mismatches, generates wave absorbing function, and Wave energy is made to be weakened；Water mist can
The effectively secondary dust for reducing explosion and generating.
Compared with existing blasting method, present invention employs horizontal decoupling charge structures, can avoid the excessive broken of rock
It is broken, reduce the dust of explosion generation；Vertical coupled charge constitution is used, can reduce and be generated because base charge energy is excessive
Excessive dust, the adsorbable dust formed by broken rock of water filling of water bag I；Use delay charge structure, water bag II and water
The water filling of bag III can be sufficiently formed water mist, and dust-laying effect is more preferably.
Implementation recited above is described only for the preferred embodiment for the present invention, not to the design of the present invention
It is defined with range.Under the premise of not departing from design concept of the present invention, method side of the ordinary people in the field to the present invention
The various modifications and improvement that method is made, should all drop into protection scope of the present invention, the method content of the present patent application, entirely
It records in detail in the claims in portion.
