Abstract
The invention discloses a method for quickly blocking a blast hole, and the method comprises the following steps: (1) after the blast hole is filled with an explosive material and a detonating tube is educed, a hole plug which is made of a fibrous material and slightly smaller than the blast hole in diameter is stuffed into the orifice of the blast hole, so that the detonating tube is close to the blast hole wall; 2) the hole plug is injected with water so that the hole plug is inflated, the orifice of the blast hole is totally plugged, and the detonating tube is tightly close to the blast hole wall. The method is characterized in that the blast hole is plugged with the hole plug made of the fibrous material, thus the method is simply, conveniently and quickly operated and excellent in security, besides the effect of plugging the blast hole is reliable and the detonating tube cannot be damaged.
Description
Technical field
The invention belongs to blasting technique field, specifically, the particularly method of a kind of big gun hole fast blocking-up.
Background technology
At present, after bursting work fills explosive, generally adopt and carry out plug-hole in two ways: a kind of is the grinding adopting rock ballast, boring formation, and existing deficiency is that speed is slow, and potential safety hazard is large; Another kind adopts accelerated cement, but cost is high, complex operation, and speed is slow, and solidify the rear extruding force to detonator greatly, easily causes detonator to damage.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple to operate, fireballing big gun hole fast blocking-up method.
Technical scheme of the present invention is as follows: a kind of big gun hole fast blocking-up method, comprises the following steps:
1) install explosive in big gun hole, after drawing detonator, the stopple be made up of fibre material more smaller than big gun hole for diameter is filled in the aperture in big gun hole, make detonator press close to blasthole hole wall;
2) water on stopple, stopple is expanded, by complete for the aperture in big gun hole shutoff, and detonator is close to blasthole hole wall.
Adopt above technical scheme, stopple can be prefabricated according to the size in big gun hole, when plug-hole, operating personnel only need complete and put into stopple and two actions of watering can be withdrawn, simple, convenient on the one hand, speed is fast, can guarantee the personal safety of operating personnel; On the other hand, stopple can guarantee the effect in shutoff big gun hole, and little to the extruding force of detonator after stopple plug-hole, and detonator can not be caused to damage.The selection of stopple can be green grass, straw, straw or other herbaceous plant be applicable to, and also can be wood chip etc., scope of selecting material be wide, and material cost is extremely low.
Described stopple is cylinder, and is made up of screw extruder, and the moulding of such stopple is simple, namely be can be made into by spiral extruder discharge, and processing and fabricating is easy, and processing cost is low.
Beneficial effect: the stopple that the present invention adopts fibre material to make comes shutoff big gun hole, not only simple, convenient, quick, security is good, and shutoff big gun hole is reliable for effect, and detonator can not be caused to damage.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
A method for big gun hole fast blocking-up, comprises the following steps:
1) install explosive in big gun hole, after drawing detonator, stopple more smaller than big gun hole for diameter is filled in the aperture in big gun hole, make detonator press close to blasthole hole wall.Described stopple is cylinder, is made up by screw extruder of fibre material.Fibre material can be wood chip or/and grass meal, also can be other be applicable to material, as long as there is water swellable after making stopple.The diameter 2-20mm less of blasthole diameter of stopple, concrete difference is determined according to actual needs.
2) water on stopple, stopple is expanded, by complete for the aperture in big gun hole shutoff, and detonator is close to blasthole hole wall.Irrigation amount is determined according to actual needs, as long as stopple can be impelled to expand.
The structure and working principle of above screw extruder is prior art, and therefore not to repeat here.
Although above, the preferred embodiments of the present invention are described; but the invention is not restricted to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic instead of determinate; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite without prejudice to present inventive concept and claim; can make like multiple types and representing; as changed the raw material of stopple; or change irrigation amount; or stopple is changed into spherical or other shape etc. be applicable to, such conversion all falls within protection scope of the present invention.
Claims (2)
1. a big gun hole fast blocking-up method, is characterized in that comprising the following steps:
1) install explosive in big gun hole, after drawing detonator, the stopple be made up of fibre material more smaller than big gun hole for diameter is filled in the aperture in big gun hole, make detonator press close to blasthole hole wall;
2) water on stopple, stopple is expanded, by complete for the aperture in big gun hole shutoff, and detonator is close to blasthole hole wall.
2. big gun hole according to claim 1 fast blocking-up method, is characterized in that: described stopple is cylinder, and is made up of screw extruder.
