Abstract
The invention relates to an improvement of a blasting dust-settling method, belongs to the field of mine blasting environmental protection, and is suitable for mine blasting engineering. The invention aims to overcome the defects of the prior art and provide a method for increasing the length of water stemming, wherein the water stemming is firstly placed into a blast hole and then injected with high-pressure water, and the water stemming plays a role in dust fall and blocking, so that the clay stemming is omitted, and the production cost is reduced. Because the water stemming increases the length and the volume of water, and high-pressure water is filled in the water stemming, the plugging effect is enhanced, and the blasting dust-settling effect is obviously improved.
Description
Technical Field
The invention relates to an improvement of a blasting dust-settling method, belongs to the field of mine blasting environmental protection, and is suitable for mine blasting engineering.
Background
The blasting dust fall method in the prior art adopts a combination mode of water stemming and clay stemming, and an electric detonator, an explosive, the water stemming and the clay stemming are arranged in a blasting hole in the combination mode. The water stemming is injected with water in the cylindrical belt body to play a role in dust fall; the clay stemming plays a role in plugging. Because the depth of the blast hole is fixed, the length of the water stemming which really plays a role of dust fall cannot be too long, and the blasting dust fall effect is not obvious. The water stemming in the prior art is firstly injected with water and then placed in a blast hole, the diameter of the water stemming is smaller than that of the blast hole, the water stemming does not play a role in blocking and only plays a role in dust fall, and therefore the water stemming needs to be blocked by clay stemming.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a method for increasing the length of water stemming. The water stemming not only plays a role in dust fall, but also plays a role in plugging, so that the clay stemming plugging is cancelled. Because the water stemming increases the length and the volume of water, and high-pressure water is filled in the water stemming, the plugging effect is enhanced, and the blasting dust-settling effect is obviously improved.
The water stemming needs a special fixture to be put into the blast hole, and then high-pressure water is injected into the water stemming by a high-pressure water gun.
By adopting the scheme, the dust settling effect of the dust settling agent is obviously improved, and the cost of clay stemming is saved.
Drawings
For the purpose of promoting an understanding of the principles of the structure and best mode for practicing the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.
FIG. 1 is a schematic view of the overall structure of the water stemming of the invention;
fig. 2 is a schematic structural view of the special water stemming clamp.
In fig. 1: the water stemming consists of a cylindrical band body 1 and a cylindrical water injection hole 2, wherein the cylindrical band body 1 and the cylindrical water injection hole 2 are formed by high-temperature pressing of high-strength flexible plastic materials. The cylindrical belt body 1 plays a role of bearing high pressure water pressure, and the cylindrical water injection hole 2 plays a role of closing the water injection hole.
In fig. 2: the special clamp for the water stemming consists of a movable operating handle 1, a movable pull rod 2, a fixed handle 3, a guard ring 4, a clamp cylinder 5, a guard ring 6 and a clamping mouth 7. The opening of the nip 7 is increased or decreased by the left-right movement of the movable operation handle 1.
Detailed Description
The specific implementation process of the invention is as follows: as shown in fig. 1 and 2, the water stemming without water injection is firstly clamped by the clamping nozzle of the water stemming special fixture and is sent to the inside of the shot hole drilled in advance, then the clamping nozzle is opened by pushing the moving operating handle of the water stemming special fixture inwards, the water stemming special fixture is pulled out from the shot hole, then water is injected into the water stemming water injection hole by the high-pressure water gun, the water pressure inside the water stemming is increased, the water stemming seals the water injection hole under the action of the water pressure, and simultaneously the water stemming expands under the action of the internal pressure, so that the frictional resistance is increased, and the effect of sealing and plugging is achieved.
When the electric detonator detonators the electric detonator, due to the resistance action of the water stemming, the explosion shock wave is not leaked to the outside of the blast hole, the rock or coal is burst by strong explosion pressure, meanwhile, the water stemming is broken, and the water atomization of the water stemming is used for reducing dust.
