Problems solved by technology

[0002] At present, the smooth surface control blasting technology commonly used in mines is the control blasting technology using less charge, uncoupled charges at intervals, small hole spacing, and small row spacing, and the blasting technology using thunderbolt tube control. Although the latter has a larger hole spacing, the blasting effect It is also better, but the operation is more demanding, the requirements for the blasting direction are stricter, the requirements for explosives are higher, and the cost is relatively higher

Embodiment Construction

[0015] Such as figure 1 Shown, a kind of water medium blasting technology of the present invention: (1) select detonation point, drill hole, adopt common 2# rock emulsion explosives, calculate the charge of every hole; Frame 2 adopts the continuous charging method of fine powder coils, connects the powder coil 1 and the nonel tube 4, and loads them into the blast hole 8 in sequence; (3) put the blast hole plug 5 with the air guide groove 6 and the water injection hole 7 At the blasthole orifice, start injecting water 3 from the water injection hole 7 of the blasthole plug 5, and the air in the hole is discharged from the air guide groove 6; (4) When the water 3 is filled, quickly insert a small piece of foam into the water injection hole 7 Simultaneously, the blast hole plug 5 is pushed into the blast hole, the blast hole 8 is closed, and then the blast hole 8 is blocked with blasting mud; (5) detonating, the water 3 is equivalent to one deck film at the moment of blasting, an...

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 [0001] The invention relates to a blasting technology, in particular to a water medium blasting technology. Background technique [0002] At present, the smooth surface control blasting technology commonly used in mines is the control blasting technology using less charge, uncoupling charge at intervals, small hole spacing, and small row spacing, and the blasting technology using thunderbolt tube control. Although the latter has a larger hole spacing, the blasting effect It is also better, but the operation is more demanding, the requirements for the blasting direction are stricter, the requirements for explosives are higher, and the cost is relatively higher. Contents of the invention [0003] The object of the present invention is to provide a water medium blasting technology, which is not only easy to operate, can realize high-quality controlled blasting with a relatively large hole distance, but also has a low cost and has the effect of eliminating dust...
