Abstract
The invention discloses a water medium explosion technology which comprises the following steps: selecting a denotation point; installing a circular support bracket on a cartridge and putting the cartridge into blast holes in sequence; putting blast hole plugs at blast hole mouths; filling water through water filling holes of the blast hole plugs; sealing the blast holes after the water is filled up; further blocking the blast holes by using stemming; and detonating so as to obtain good glazes. The technology is simple to operate and low in explosion cost, and the water further has the function of dust suppression after the explosion.
Description
Technical field
The present invention relates to a kind of blasting technique, relate in particular to a kind of aqueous medium blasting technique.
Background technology
At present; Mine general smooth controlled blasting technology for adopt few powder charge, at interval coupling charging, aperture apart from, float is apart from the controlled blasting technology and adopt thunderbolt management and control system blasting technique, though latter's pitch-row is bigger, demolition effect is also better; But operation is harsh; Blasting direction is required strictness, explosive is had relatively high expectations, cost is relatively also higher.
Summary of the invention
The object of the present invention is to provide a kind of aqueous medium blasting technique, not only simple to operate, can realize big pitch-row high quality control explosion, and also cost is lower, the effect of the dirt that goes out in addition simultaneously.
A kind of aqueous medium blasting technique of technical scheme of the present invention may further comprise the steps:
(1) select fire point, the explosive payload in every hole is calculated in boring;
(2) circular housings is installed on powder stick, adopts thin powder stick continuous charging mode, connect powder stick and detonator, the big gun hole of packing into successively;
The big gun hole stopple that (3) will have air slot and a water injection hole places aperture, big gun hole, and the water injection hole of stopple begins water filling from the big gun hole, and air is discharged by air slot in the hole;
(4) after fills with water, fast the fritter foam to be filled in water injection hole and simultaneously big gun hole stopple is pushed in the hole, big gun hole, the big gun hole is stopped up with stemming again in sealing big gun hole;
(5) ignite, be equivalent to a skim at the instantaneous water of explosion, the shutoff crack obtains light face preferably;
Said big gun hole stopple is processed by plastic foam.
Beneficial effect of the present invention is: can realize big pitch-row explosion, owing to be equivalent to a skim at the instantaneous water of explosion, and the shutoff crack, blasting direction obtains light face preferably along the direction in adjacent big gun hole; The active force of explosion is not to act directly on the crag, and is lighter to the destruction of crag; Simple to operate, blasting cost is lower, and water can also play the effect of the dirt that goes out after the explosion.

The specific embodiment
As shown in Figure 1, a kind of aqueous medium blasting technique of the present invention: fire point is selected in (1), and common 2# rock emulsion explosive is adopted in boring, calculates the explosive payload in every hole; (2) circular housings 2 is installed on powder stick 1, adopts thin powder stick continuous charging mode, connect powder stick 1 and detonator 4, the big gun hole 8 of packing into successively; The big gun hole stopple 5 that (3) will have air slot 6 and a water injection hole 7 places aperture, big gun hole, the water injection hole 7 beginning water fillings 3 of stopple 5 from the big gun hole, and air is by air slot 6 discharges in the hole in; (4) after fills with water 3, fast the fritter foam to be filled in water injection hole 7 and simultaneously big gun hole stopple 5 is pushed in the hole, big gun hole, big gun hole 8 is stopped up with stemming again in sealing big gun hole 8; (5) ignite, be equivalent to a skim at the instantaneous water 3 of explosion, the shutoff crack obtains light face preferably.
Claims (2)
1. aqueous medium blasting technique is characterized in that: may further comprise the steps:
(1) select fire point, the explosive payload in every hole is calculated in boring;
(2) circular housings is installed on powder stick, adopts thin powder stick continuous charging mode, connect powder stick and detonator, the big gun hole of packing into successively;
The big gun hole stopple that (3) will have air slot and a water injection hole places aperture, big gun hole, and the water injection hole of stopple begins water filling from the big gun hole, and air is discharged by air slot in the hole;
(4) after fills with water, fast the fritter foam to be filled in water injection hole and simultaneously big gun hole stopple is pushed in the hole, big gun hole, the big gun hole is stopped up with stemming again in sealing big gun hole;
(5) ignite, be equivalent to a skim at the instantaneous water of explosion, the shutoff crack obtains light face preferably.
2. aqueous medium blasting technique, it is characterized in that: said big gun hole stopple is processed by plastic foam.
