Description
Technical field
The invention belongs to construction blasting field, it is adaptable to need blast working in building demolition, tunnel excavation, mine broken rock
Construction industry, specifically a kind of closing cold blasting method of blast hole liquid carbon dioxide.
Background technology
World today's building, tunnel, mine broken rock, mining construction technology, are exactly explosive except mechanical rock breaking construction
Blast working, such as explosives and detonators；The former efficiency is very low, and the latter is dangerous greatly, and easily causes the loss of explosive, is formed
Great terrified case.The generation in 30, of such as 2015 on Septembers causes 11 people dead altogether in 18 serial blasts of Liuzhou
Die, 51 people it is injured, major criminal cases.Crime personnel Wei Yinyong produces contradiction because of quarrying production with neighbouring villager, relevant unit,
Then the method for deliberating to take " defalcating ", gets more, clears up and discharges less, and the regulatory bodies such as public security of out-tricking hoard explosives and detonators, from
Self-cocking action device processed, causes significant damage.Such case also occurs repeatedly on Xinjiang, Inner Mongol, Gansu, Shaanxi and other places.In order to
A large amount of chemical explosive blast crackings for using in building demolition, tunnel excavation, mine broken rock are solved, efficiency is low, dangerous big, holds
The loss of explosive, formation considerable safety supervision liability accident, and explosive application, approval, storage etc. are easily caused, public affairs are both needed to
The special examination ＆ approval of peace office, the problems such as the cycle is long, are a solution party well using the cold blasting technique of liquid carbon dioxide
Method；But it is small that the existing cold blasting technique of liquid carbon dioxide has plasting damage effect, the problems such as high cost.
On January 1st, 2016《People's Republic of China's anti-terrorism method》Formal issuing and implementation, this is for anti-probably anti-terrorism
One moment of history.For explosives and detonators bursting work, this will imply that the rising of cost, because《The Chinese people
Republic's anti-terrorism method》21st article, 22 articles, clear stipulaties must carry out electronic mark, automatic identification skill to explosive
Straight line is increased more than 2-20 times by art, the cost of explosive, supervision cost.
Carbon dioxide explosion explosion (cold quick-fried) technology, is exactly carried out quick-fried using liquid carbon dioxide as explosion explosive material
The technology of broken explosion operation.Specifically, exactly liquid carbon dioxide is compressed in special carbon dioxide explosion blasting cartridge,
Then blasting cartridge is loaded into blast hole, and is detonated using special intelligent carbon dioxide initiation system.During detonation, initiator
The quick heating rod lighted in explosion blasting cartridge, in 4 milliseconds, is up to pressure 20-40Mpa liquid carbon dioxides and quickly heats
More than 600-1000 times of expansion, so as to produce powerful impulsive force, forms blast.And the carbon dioxide that can be loaded by control
The methods such as quality control bursting strength, and realization such as makes a sudden snatch, opens a way, cutting into a mountain, tunneling, digging up mine, removing at the Area Objects in many ways.
Carbon dioxide explosion explosion (cold quick-fried) technology, will rewrite broken rock, the history of explosion, step up new technology height, but
Small, the high expensive that is that this technology there is also plasting damage effect, the blasting cartridge influence demolition effect and spoilage that use are higher etc. to ask
Topic.
The content of the invention
In view of the foregoing defects the prior art has, it is cold quick-fried this application provides one kind closing blast hole liquid carbon dioxide
Broken method, does not use blasting cartridge, directly injects liquid carbon dioxide in blast hole, and blast hole is closed using hole packer, reinjects
Liquid carbon dioxide carries out cold explosion, and it is small to solve the plasting damage effect that the cold blasting technique of liquid carbon dioxide is present, high cost
It is that the optimization of the cold blasting technique of existing liquid carbon dioxide is improved etc. technical problem.
To achieve the above object, the technical scheme of the application use is：The cold explosion side of closing blast hole liquid carbon dioxide
Method, comprises the following steps that：
S1:First, blast hole is bored on shot rock；
S2:Then hole sealing device is installed, one end that initiator is provided with hole sealing device is entered deeply into the pores, hole sealing device whole
In immersed hole, high pressure liquid injection port, carbon dioxide liquid injection port, the lead mouth of pipe are reserved in outside blast hole；
S3：High pressure liquid injection port connects high pressure liquid fluid injection gun, hole sealing device fluid injection elastic housing expansion plugging blast hole；
S4：Carbon dioxide liquid injection port connects liquid carbon dioxide liquid injection pipe, is needed in blast hole injection according to explosion design
Quantitative liquid carbon dioxide；
S5：The initiator wire that lead mouth of pipe side will be reserved in is connected according to mode in parallel；Initiator is powered and ignites
Liquid carbon dioxide in blast hole, completes explosion.
Further, the hole sealing device, including：Housing, fairlead, initiator, initiator wire, high pressure liquid injection port,
Carbon dioxide liquid injection port, carbon dioxide liquid injection pipe；High pressure liquid injection port, carbon dioxide liquid injection port, the lead mouth of pipe are placed in the one of housing
End, the lead mouth of pipe is connected with fairlead, and fairlead runs through whole housing and leans out the other end of housing, and the end is provided with initiator,
Carbon dioxide liquid injection pipe runs through whole housing, and carbon dioxide liquid injection port is connected with carbon dioxide liquid injection pipe；The initiator wire
It is placed in fairlead, and is connected with initiator.
Further, the housing is elastic shell.
Further, the carbon dioxide liquid injection port is located between high pressure liquid injection port, the lead mouth of pipe.
Further, the fairlead is in close contact with carbon dioxide liquid injection pipe.
The present invention can obtain following technique effect due to using above technical scheme：
(1) plasting damage effect is big；The blasting cartridge intensity that original blasting cartridge explosion is used is high thus thickness of pipe wall, the liquid that can be injected
Amount of carbon dioxide only has about 1/3rd of explosion pore volume, and the application does not use blasting cartridge to be directly injected into liquid carbon dioxide
In blast hole, injection rate increases by 2 times than blasting cartridge, and plasting damage effect is directly improved because the quality of carbon dioxide blast source increases；
(2) the initial stage input and use cost of explosion are reduced；Because explosion blasting cartridge is using high-strength seamless steel pipe system
Into the initial stage of being more expensive to manufacture is needed than larger input, and damage in use also results in that blasting cost is high, and the application is not
Using explosion blasting cartridge, thus reduce use cost；
(3) construct simple and convenient, it is easy to promote；Hole sealing device integrate sealing of hole, fluid injection, ignite function reduce construction
Difficulty, it is possible to which recycling also reduces cost.
