Specific embodiment
In conjunction with attached drawing 1~3, a kind of outdoor limestone mine explosion dust-removing method, comprising the following steps:
(1) it drills: according to actual landform condition, being drilled with blasthole on bursting work platform.
(2) it fills hole: A, stoppering explosive 1 to blasthole bottom；
B, empty bottom water bag 2 is put in 1 top of explosive and is in close contact with 1 top surface of explosive, bottom water bag 2 be equipped with
The water injecting pipeline that bottom water bag 2 is connected to, fills water into bottom water bag 2 by water injecting pipeline；
C, after bottom water bag 2 fills water, tamper 3 is put into blasthole, 3 bottom surface of tamper and 2 top surface of bottom water bag are tight
Contiguity touching, 3 top slot milling of tamper, and being put into empty top water bag 4 keeps top 4 bottom surface of water bag and 3 top surface of tamper tight
Contiguity touching, top water bag 4 are equipped with the water injecting pipeline being connected to top water bag 4, are filled by water injecting pipeline into top water bag 4
Water.
(3) it moistens processing: before detonation, the drilling rock powder near blasthole mouth and explosion body surface dust will be deposited in water
Wet processing is carried out, prevents it in explosion from forming fugitive dust.
(4) networking explosion: being connected to the network burst region, and quick-fried using the loosening of step medium-length hole msdelayed light emission
Broken, two one section of blastholes, the outer 3 sections of detonators of the built-in 15 sections of detonating capsules of blasthole, blasthole connect network.
As the present embodiment preferred embodiment, the top water bag 4, bottom water bag 2 are tubulose water bag, the top
Portion's water bag 4, bottom water bag 2 are blow molded using LDP- low density polyethylene (LDPE), and the water bag wall thickness is 0.06mm-0.08mm.
Traditional water bag is to select colourless, tasteless, transparent, soft, environment-friendly materials latexes or vinyon injection molding
It forms, the toxic gases such as carbon monoxide can be generated after burning, unburned residue totally is difficult to be decomposed by edaphon, produces
Raw white pollution.Therefore, present invention top water bag 4, bottom water bag 2 are added using " LDP-low density polyethylene (LDPE) " by blow moulding
Tubular film made of work is as water bag material, environment-friendly high-efficiency, economical and practical water bag material, and its burning is rapidly and water bag
Residue compares traditional water bag can be faster by the microorganism decomposition of soil；
Water bag wall thickness can influence water droplet and spread around, and water bag wall thickness is excessive, do to the scattered water droplet of throwing negative
Function is more, influences the dispersal velocity and radius of water droplet；Water bag wall thickness is small, and resistance to compression and abrasion-resistance are small, be easy water filling,
Leak is ruptured during water bag wall and drilling wall friction and filling, the demolition effect of explosive had not only been influenced but also had lost water bag method water
Mist droplet dust-laying effect.
The wall thickness for the maximum speed and water bag that water droplet is shed, which exists, does negative work relationship, and water mist dispensing radius is because of water bag wall
To the impact force of water when face can offset explosive charge, in a certain range, water bag wall thickness is bigger, and the function and effect of counteracting are got over
Greatly, water mist dispensing radius is smaller, when water bag wall thickness is 0.06mm-0.08mm, water bag not cracky, and the water that water bag is formed after explosion
Mist is ideal, can play effective dust-laying effect.
As the present embodiment preferred embodiment, the blasthole diameter is 120mm, top water bag 4, bottom water bag 2
Length be 1200mm.
As the present embodiment preferred embodiment, the blasthole diameter is 140mm, top water bag 4, bottom water bag 2
Length be 1500mm.
As the present embodiment preferred embodiment, the length of the tamper 3 is 400mm.
As the present embodiment preferred embodiment, top water bag 4, bottom water bag 2 fill tight with blasthole inner wall after water
Contiguity touching forms sealing state.
The size of water is to influence the principal element of dust removing effects, it is considered that water increase can effectively improve dedusting effect
Rate, in the case where other conditions are identical, certain water corresponds to certain maximum except dust quantity, the shadow of the diameter of water bag by bore diameter
It rings, water bag needs to be close to after charging the wall surface that drills, and forms sealing state, water storage diameter i.e. bore diameter, water bag are long
The size of diameter ratio is practical, and reflect is exactly number in certain bore diameter moisture storage capacity.Water in top water bag 4 and bottom water bag 2
It is under by the instant impact effect after explosive charge, so that top water bag 4 and the rupture of 2 moment of bottom water bag form water
Water mist water droplet and shed around, certain water corresponds to certain dustfall content.
Water bag plugging method explosion depositing dust mainly makes the water in water bag form water droplet, water mist mist according to blasthole explosive charge
Drop is all to have a certain size, and water mist water droplet captures and wet grit blasting dust, and water in water bag is made to form water after explosion
The size and its water droplet range of mist mist droplet particle size and its efficiency of seizing dust have much relations；The water droplet that is formed after explosion with
Efficiency of seizing dust is best when grit particle size is suitable, and water droplet is too small, is difficult to keep grit wet grit is collided with it；
Water droplet is too big, and dispensing velocity is low, area is small, can only collide with small-scale dust, cementing, cohesion keeps dust wet.
Water droplet is excessive or too small can all influence to catch dirt ability and influence dust-laying effect.
One, test effect
1, experimental group: double water bag explosions are provided with top water bag and bottom water bag, and after powder charge completion, solid
There is stemming length to consider water bag length ratio, riding position under conditions of 400mm.
Contrast groups 1: single water bag explosion is only arranged top water bag, is in close contact tamper bottom surface and explosive top surface,
Intrinsic stemming length considers water bag length ratio, riding position under conditions of being 400mm.
Contrast groups 2: without water bag explosion.
2, demolition site uses the msdelayed light emission standing of step medium-length hole, and two one section of blastholes, built-in 15 sections of blasthole are risen
Quick-fried detonator and the outer 3 sections of detonator relay networks of blasthole, divide without three kinds of water bag, single water bag and double water bags each explosions of situation three times.
3, experimental result
The fixed point of 1. blasting dust concentration of table measures table
By upper table data it is found that carrying out explosion using the improved double water bags of the present invention, dust concentration can be effectively reduced, solve
Blasting dust problem.
The present invention and its embodiments have been described above, this description is no restricted, shown in the drawings
Only one of embodiments of the present invention, actual structure is not limited to this.All in all if the ordinary skill of this field
Personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution phase
As frame mode and embodiment, be within the scope of protection of the invention.
