Description
Technical field
The invention belongs to finely control blasting technique field, in particular to a kind of fine explosion abrasive material Concentrated charge device and
Its application method.
Background technology
Engineering explosion is directly development of the national economy service as a kind of means of engineering construction, has become China's economy
One of indispensable important support technology in social construction.At present engineering explosion technology have been widely used with mining, build
(structure) builds numerous engineering fields such as object dismounting, road and rail construction, water conservancy and hydropower.It is worth noting that in numerous engineering explosions
In, rock blasting is wherein most important component part.In the Rock Blasting Engineering early stage of development, people only pay attention to utilize explosive
Explode the energy discharged, achievees the purpose that " to destroy ", as long as can reach catalase purpose.With theory of blasting with
The development of rock mechanics should also reach to non-it was recognized that not only to achieve the purpose that fractured rock during explosion
The protection of burst region rock, for example, tunnel drilling and blasting construction in the damage of country rock answer it is as small as possible in favor of later stage supporting with enclose
The permanent stability of rock；Or to achieve the purpose that explosive forming after explosion, such as in valuable stone material Cutting Blasting, after explosion
The complete plane of disruption can be formed along design profile line.In consideration of it, to propose photoface exploision, presplit blasting, grooving in succession quick-fried by people
Several controlled blasting methods such as broken, CUMULATIVE BLASTING and Cutting Seam Cartridge Blasting.Nowadays engineering explosion is even more to enter new hair
Exhibition stage, i.e. " fine explosion " technological phase.In blasting process, in addition to the two kinds of purposes that reach above-mentioned, should also it meet fried
Medicine energy maximization utilizes, blasting process is safe and reliable, bursting work economical rationality purpose.
Main using face notched blasting, CUMULATIVE BLASTING and Cutting Seam Cartridge Blasting in rock controlled blasting at present.But
These three methods respectively have advantage and disadvantage.Notched blasting method breaking effect is good, and dosage is few, but grooving needs specific drilling tool to dig, and bores
Hole is less efficient, and difficulty of construction is big；CUMULATIVE BLASTING method orientation is apparent, can effectively control initial crack and be formed, but energy gathering cap
Processing is complicated and costly；Cutting Seam Cartridge Blasting method technology is simple, easy for construction, and joint-cutting pipe can effectively protect country rock subtracts
Small loss, but initial crack is formed not as good as the above two.
The essence of rock blasting is the formation, extension and the formation in final fracture face of rock initial crack.Conventional blast
Method is to utilize the mesh for reaching rock blasting under the quasi-static effect collective effect of Explosive stress wave in blast process and detonation gas
, poor controllability, blast working period length, explosive energy interest rate are compared with small, rock convergence measure is big, support cost is high.Modern fine
Blasting technique proposes that in blasting process problem above should be overcome, thinks in the premise of guarantee demolition effect, reduce rock convergence measure, improve
Explosive energy utilization rate, while to control construction cost.
Invention content
To solve above-mentioned existing problem, the present invention provides one for deficiency present in existing rock Controlled blasting technique
The fine explosion abrasive material Concentrated charge device of kind, the device have CUMULATIVE BLASTING technology and water-jet technology, segment algorithm technology etc.
Machine combines, and takes its advantage, improves insufficient, industrial simple, the safe and reliable, convenient construction of making, and extraordinary can control
Demolition effect processed reduces explosion rock convergence measure, effectively plays Mohaupt effect, jet impulse effect and retaining wall effect.The present invention
Another be designed to provide the fine explosion abrasive material Concentrated charge device blasting construction method, this method simply may be used
It leans on, convenient for construction.
