Abstract
A suspension type blaster comprises a blasting charge and igniters of the suspension type blaster. The upper portion of the blasting charge is connected with a first lifting rope, and each igniter comprises a detonator arranged in the blasting charge and a detonating cord connected with the detonator. A guide pipe is further arranged on one side of the blasting charge, and the first lifting rope is a steel wire rope. At least two set of igniters are arranged to guarantee successful detonation. The suspension type blaster is simple in structure, convenient to operate and capable of avoiding the situation that construction personnel carries out blasting operation construction in a pioneer well, guarantees construction safety, can greatly reduce construction cost, meanwhile, improves working efficiency and is very suitable for being used in the grotto of a vertical shaft structure.
Description
Technical field
The utility model relates to a kind of blaster, particularly a kind of suspension type blaster for underground cavern excavation.
Background technology
In the underground excavation engineering construction, usually run into the shaft structure cavern, such as gate shaft, pressure regulation vertical shaft, diversion vertical shaft etc.For this class vertical shaft cavern, the pilot shaft excavation is carried out first in general employing, carries out the construction method that vertical shaft digs again, and wherein the effect of pilot shaft is mainly as the slide slag passage that digs.And the construction method of pilot shaft has two classes usually, and namely anti-well bores method and drilling and blasting method.Because anti-well brill method adopts the raise boring machine drilling and forming hole, construction cost is higher, and success rate is lower, therefore adopt drilling and blasting methods, and in the drill bursting construction process, workmen's operation such as must in pilot shaft, hole, slag tap more, potential safety hazard is very outstanding, and operating efficiency is also low.
Summary of the invention
The purpose of this utility model provides a kind of suspension type blaster, can avoid workmen's security hidden trouble that operation exists in pilot shaft, and also greatly raising of operating efficiency, and construction cost is also low.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of suspension type blaster, comprise the blasting charge and apparatus to cause bursting thereof, the top of the blasting charge is connected with the first lifting rope, and described apparatus to cause bursting comprises the detonator of being located at blasting charge inside and the primacord that is connected with detonator.
One side of the described blasting charge also is provided with guide pipe.
Described the first lifting rope is seizing wire.
Described apparatus to cause bursting is at least 2 covers, with the ignition that assures success.
The suspension type blaster that the utility model provides, simple in structure, easy to operate, be highly suitable in the shaft structure cavern and use, and rock ballast will directly be scattering into the shaft bottom after the explosion, so that the workmen needn't slag tap, be conducive to construction safety in well.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is blast hole plane of arrangement schematic diagram in the pilot shaft.
Fig. 3 is that the utility model is installed and used schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model comprises the blasting charge 2 and apparatus to cause bursting thereof, and the top of the blasting charge 2 is connected with the first lifting rope 1, and described apparatus to cause bursting comprises the detonator 3 of being located at blasting charge inside and the primacord 4 that is connected with detonator.
One side of the described blasting charge 2 also is provided with guide pipe 5.
Described the first lifting rope 1 is seizing wire.
Described apparatus to cause bursting is at least 2 covers.
It is of the present utility model that to install and use process as follows:
1) finishes first as shown in Figure 2, the boring work of pilot shaft 7 interior all blast holes 6 in the vertical shaft 8 according to designing requirement.
2) by the hole suspension type blaster is installed: as shown in Figure 3, adopt the second lifting rope 9 to pierce in the sleeve pipe 5 of the present utility model, afterwards transfer bottom, hole to blast hole 6 together with the utility model, then continue to transfer one section second lifting rope 9, prop up workmen in the hole is tethered in slightly larger in diameter the second lifting rope 9 in the stopper 10 of blast hole end in the construction of pilot shaft, the staff of blast hole 6 tops second lifting rope 9 of pulling back, stopper 10 is blocked at the bottom of blast hole 6 holes, poured into sandstone 11 from blast hole 6 at last blast hole is stopped up.
3) explosion: after the blaster installation of all blast holes, all primacords are connected with firing switch outside the aperture, can carry out explosion.Rock ballast will directly be scattering into the shaft bottom after the explosion, so the workmen needn't slag tap in well, and this also is conducive to construction safety.
