Description
Technical field
The utility model relates to a kind of blasting flyrock protection network, is applicable to the flyrock protection in open cut ore mine and engineering explosion earthwork evacuation operation process.
Background technology
Explosion has the advantages such as efficiency is high, the time is short in pledge excavation process, is the most applicable and effective method of current fractured rock, in mine, department's extensive use such as traffic, water power, urban construction.Blasting flyrock refers to that indivedual fragments of blasting body or small part fragment, by throwing, occur that beyond thought fragment flies to throw phenomenon.Though it is indivedual that blasting flyrock belongs to, because uncertainty and the casting distance of its thrown direction is difficult to accurate calculating, the safety that tends near personnel Gei Bao district, installations and facilities, buildings or structures etc. causes serious threat.According to statistics, 1982～1985 years surface blasting accident borehole blasting slungshot accidents of the U.S. account for 59.1%, and Japan is in the demolition accident occurring for 1979, and blasting flyrock accident is up to 61%.In China, the casualties, the buildings or structures damage accident that because of blasting flyrock, cause have accounted for 15%～20% of whole demolition accident, and China's surface mine blasting flyrock casualty accident accounts for 27% of whole demolition accident.As can be seen here, blasting flyrock is one of latent defect factor the most serious in engineering explosion, is generally acknowledged public nuisance from blasting.In general, by the flying speed of blasting flyrock and harm, blasting flyrock mainly occurs with impelling and two kinds of forms of throwing.Pinpoint blasting slungshot is mainly because resisting deficiency or overcharging, and explosion dump energy goes out indivedual rubble throwings rock main body and forms.This kind of blasting flyrock throwing speed is generally not high, and influence area is less, but often occurs destructive destruction in coverage; The reason that impelling blasting flyrock produces is mainly relevant with the weak face being existed in blasting medium structure and quick-fried raw crack.
Blasting flyrock endangers as a great explosion, is one of problem of paying close attention to the most such as numerous experts, scholar and mine worker always.By optimal design and well construction, can effectively control the generation of a large amount of blasting flyrocks, but will definitely guarantee not produce a small amount of or indivedual blasting flyrocks, under current blasting technique condition, also be difficult to reach.Therefore, the security protection work of blasting flyrock is absolutely necessary.At present, in blast working operation, conventional safeguard procedures have: glue curtain, chaste tree basketry (bamboo basketry) and the wire netting etc. that in blasting body, cover straw bag (or straw screen or mat), waste and old adhesive tape (or sebific duct) establishment; Enclosing framed bent etc. is set near blasting body.Yet above conventional flyrock protection measure exists the shortcoming and defect such as difficulty of construction is large, covering is heavy, difficult carrying, not reproducible use to some extent, and flyrock protection effect is limited.
Summary of the invention
For the technical deficiency of current flyrock protection measure, for effective controlled blasting slungshot, improve demolition effect, create good bursting work environment, the utility model proposes the adjustable blasting flyrock protection network of a kind of flexibility.This protection network can effectively limit the lumpiness of blasting flyrock, shortens the distance of dispersing of slungshot, prevents the generation of blasting flyrock accident, guarantees the safety of bursting work.
For realizing above-mentioned purpose of the present utility model, the technical scheme of blasting flyrock protection network employing that a kind of flexibility of the utility model is adjustable is:
A kind of flexibility of the utility model is adjustable blasting flyrock protection network, it comprises protection network, described protection network is to be overlapped and formed by hinges by net sheet; Four ends at protection network connect respectively one section of buffer rope, in the end of buffer rope, are provided with counter balance pocket.The length of buffer rope can be adjusted according to site work environment, hole pattern parameter and rock property etc., and adopts counter balance pocket that the end of buffer rope is fixed.
The mesh of protection network is to adopt cross buckle to connect and compose by steel wire rope; Length >=the 15cm of the lap segment of adjacent net pieces.The weight of each counter balance pocket is 100～200kg.
Described net sheet specification is 2m * 2m, and mesh size is 10cm * 10cm; Described buffer rope and protection network mesh wirerope diameter are all 10mm.
The beneficial effect of a kind of flexibility of the utility model is adjustable blasting flyrock protection network is: this blasting flyrock protection network can effectively reduce blasting flyrock lumpiness and stone fling distance, prevent the generation of demolition accident, protection network is flexible protective, its intensity and toughness are better, frangibility, can reuse, and protective materials is not cheap, method of operating is simple and easy to do, safe and reliable, and flyrock protection effect is very remarkable.
Accompanying drawing explanation
Fig. 1 is the planar structure schematic diagram of the adjustable blasting flyrock protection network of a kind of flexibility of the utility model.
Reference numeral is: 1-protection network, 2-buffer rope, 3-counter balance pocket, 4-hinges, 5-lap segment, 6-cross buckle.
The specific embodiment
For further describing the utility model, below in conjunction with accompanying drawing, the adjustable blasting flyrock protection network of a kind of flexibility of the utility model is described in further detail.
The planar structure schematic diagram of the adjustable blasting flyrock protection network of a kind of flexibility of the utility model as shown in Figure 1 finds out, a kind of flexibility of the utility model is adjustable, and blasting flyrock protection network is to be connected and composed by protection network 1, buffer rope 2, counter balance pocket 3.According to on-the-spot explosion scope, determine flyrock protection web area and net sheet quantity, after blasting network has connected, the net sheet of protection network 1 is covered in quick-fried district one by one, the mesh of protection network 1 adopts cross buckle 6 to connect, between adjacent net pieces, adopt hinges 4 to connect, length >=the 15cm of lap segment 5, four ends at protection network 1 connect respectively one section of buffer rope 2, its length can be according to site work environment, hole pattern parameter and rock property etc. are adjusted, finally adopt counter balance pocket 3 that the end of buffer rope is fixed, form collection protection network 1, buffer rope 2 and counter balance pocket 3 are in the blasting flyrock guard system of one.
A kind of flexibility of the utility model the is adjustable blasting flyrock protection network at the scene technological process of bursting work flyrock protection is:
(1) according to explosion scope of design, determine the region of flyrock protection, determine the area of protection network 1, calculating required specification is the net sheet quantity of 2m * 2m; According to site work environment, determine the length of buffer rope 2.
(2), after blast hole projectile filling, obstruction, blasting network have connected, Bao district covered protection net net sheet, adopts hinges 4 that adjacent net sheet is coupled together one by one, guarantees lap segment 5 length >=15cm; In protection network overwrite procedure, note the protection to blasting network, prevent that protection network from covering operating failure initiation net, to avoid the generation of the demolition accidents such as blind big gun.
(3) end of flyrock protection net 1 is connected with buffer rope 2, adopts the counter balance pocket 3 of field fabrication that the other end of buffer rope 2 is fixed.Counter balance pocket 3 is arranged in four angles of soft protecting net, the heavy 100～200kg of each counter balance pocket 3.
(4) after protection network has covered, personnel's general evacuation in quick-fried district fence coverage, send time break while reaching initiation conditions, Jing Bao district checks that after releasing restricted speed signal, bursting work personnel enter quick-fried district and reclaim blasting flyrock protection network, so that continue next time to reuse.
