Abstract
The invention discloses a compound energy-concentrating blasting cartridge and a production method thereof. The blasting agent is arranged in a double-layer tube, the double-layer tube is respectively provided with an inner tube kerf and an outer tube kerf, and couplant water is added in the clearance between the two tubes. Thus, the blasting cartridge firstly produces high pressure gas jets at the moment of blasting, water jets are formed through the energy concentration at the kerf of the inner tube, and the energy of the water jets are strengthened through the energy concentration at the kerf of the outer tube to form high pressure water jets, thereby impacting the wall of the blast hole and achieving the goal of oriented cracking. Thus, from the perspective of energy concentration, the compound energy-concentrating blasting cartridge can form the effect of energy concentration twice, which is twice as the energy concentrated by a normal cut blasting cartridge; and from the perspective of enclosing rock protection, the compound energy-concentrating blasting cartridge adopts a double-layer tube which is twice as the common cut blasting cartridge, and the enclosing rock protection effect is better than that of the common cut blasting cartridge, thereby further reducing the supporting cost.
Description
Technical field
What the present invention relates to is a kind of compound energy-concentrating explosion cartridge bag and production method thereof, belongs to the CUMULATIVE BLASTING field.
Background technology
Since phase early 1950s, Sweden has adopted since the photoface exploision, and many countries have also carried out lot of experiments research to photoface exploision in succession.At present, China is in the excavation construction, and photoface exploision is also popularized in an all-round way, and becomes a kind of construction method of standard.
Nearly decades, China is to the quick-fried mechanism of light, the quick-fried charge constitution of light, the time difference of detonating, guide effect, the quick-fried parameter of light etc. have been carried out large quantity research, develop low-density, low explosion velocity, low power, low-density Special explosive for smooth blasting, AN-TNT containing explosive small diameter medicine roll, aqueous gels small diameter medicine roll, carried out field experiment.But really reach the also few of smooth demolition effect in the present well lane engineering of China, except managerial reason, main cause also has: the quick-fried borehole spacing of (1) light is less, and the boring workload is larger; (2) normal optical is quick-fried can not be completed into hydraulically smooth surface at the joints development rock mass; (3) normal optical quick-fried in the blast action in single big gun hole do not have directionality.
In order fundamentally to improve the quick-fried technology of light, forefathers improve bursting quality from joint-cutting directional blasting method, cumulative directional fracture blasting, three kinds of approach of joint-cutting cartridge bag directional fracture blasting.Wherein the joint-cutting cartridge bag is less demanding to hole, and cartridge bag is made well and extensively adopted, but the application of joint-cutting cartridge bag mostly is based upon the joint-cutting to cartridge bag, and the effect of cumulative is limited, and explosive energy does not take full advantage of.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of compound energy-concentrating explosion cartridge bag is provided, increase on the one hand the quick-fried borehole spacing of light, reduce the boring workload, improve operating speed; Improve on the other hand the explosive energy utilization rate, reduce the damage to country rock, reduce support cost, effectively improved the explosive energy utilization rate, improved the effect of cumulative.
For realizing above technical purpose, the present invention will take following technical scheme:
A kind of compound energy-concentrating explosion cartridge bag, comprise the big gun hole and place joint-cutting cartridge bag in the big gun hole, described joint-cutting cartridge bag comprises the joint-cutting inner tube and places explosive in this joint-cutting inner tube, and vertically offer the inner tube joint-cutting on the tube wall face of joint-cutting inner tube, also be provided with the joint-cutting outer tube between described big gun hole and the joint-cutting cartridge bag, vertically offer the outer tube joint-cutting on the tube wall face of this joint-cutting outer tube, and the wide seam width than outer tube joint-cutting of the seam of inner tube joint-cutting, outer tube joint-cutting and inner tube joint-cutting are oppositely arranged simultaneously, are marked with couplant water between big gun hole wall and the explosive in addition.
Be 180 ° on the described joint-cutting inner tube and offer symmetrically the wide inner tube joint-cutting between 1.0～2.0mm of seam, be simultaneously 180 ° on the joint-cutting outer tube and offer symmetrically that seam is wide to be the outer tube joint-cutting between 3.0～5.0mm.
Be provided with packed layer in the gap between joint-cutting inner tube and the joint-cutting outer tube.
Packed layer is arranged between the joint-cutting outer wall of inner tube face and joint-cutting outer tube of inner tube joint-cutting both sides.
The joint-cutting outer tube diameter is 1.3～1.8 times of joint-cutting diameter of inner pipe.
The diameter of joint-cutting outer tube is 1.8～2.5 times of explosive diameter.
The bottom of explosive is provided with rebasing.
Fill with couplant water in the big gun hole.
According to above technical scheme, can realize following beneficial effect:
Compound energy-concentrating explosion cartridge bag of the present invention at first produces the gases at high pressure jet in explosion moment, then by the cumulative of inner tube joint-cutting, forms water jet, water jet passes through again the cumulative of outer tube joint-cutting, energy is further strengthened, and then impacted the big gun hole wall, reach the purpose of directional fracture.Hence one can see that, and from the angle of cumulative, this compound energy-concentrating explosion cartridge bag can form the effect of twice cumulative, is the twice of conventional joint-cutting cartridge bag cumulative; From the angle of protection country rock, this compound energy-concentrating explosion cartridge bag adopts bimetallic tube, is the twice of conventional joint-cutting cartridge bag, and the effect of its protection country rock is better than conventional joint-cutting cartridge bag, and then reduces support cost.
Another technical scheme of the present invention provides a kind of method of producing above-mentioned compound energy-concentrating explosion cartridge bag, may further comprise the steps: (1) on joint-cutting inner tube and joint-cutting outer tube, offer accordingly respectively the seam wide between 1.0～2.0mm the inner tube joint-cutting and stitch wide outer tube joint-cutting between 3.0～5.0mm; (2) the joint-cutting outer wall of inner tube face in inner tube joint-cutting both sides arranges packed layer; (3) arrange in the explosive bottom rebasing so that explosive places the center of joint-cutting inner tube; (4) the joint-cutting inner tube that explosive is housed is placed in the joint-cutting outer tube, and so that inner tube joint-cutting and outer tube joint-cutting be oppositely arranged; (5) cartridge bag that step (4) is obtained is packed diameter into than the big gun hole of the large 1.5～2.5mm of outer tube diameter, adds simultaneously couplant water in the big gun hole and arrives certain height and get final product.
According to above technical scheme, the preparation method of compound energy-concentrating explosion cartridge bag of the present invention is easy and simple to handle as can be known, and simultaneously, this technical scheme increases the quick-fried borehole spacing of light on the one hand, reduces the boring workload, improves operating speed; Improve on the other hand the explosive energy utilization rate, reduce the damage to country rock, reduce support cost.
