Abstract
The utility model discloses adopt to be equipped with the chuck for being fixed with annular on inserting groove, the middle part inwall of pipe collar on overhead caving powder charge pvc pipe fastening means, including pipe collar, the two ends port of pipe collar at the beginning of underground mine working face.Powder charge pvc pipe is connected by the utility model, it is to avoid damage of the primacord in junction caused by bending, it is ensured that Detonation Initiation Effect.Inserting groove corresponding with the mouth of pipe of powder charge pvc pipe is equipped with the utility model on the two ends port of pipe collar, in powder charge, due to the inhibition of the pipe collar mouth of pipe, pack can not glide, reduces degree of packing in powder charge difficulty, hole big and uniform, it is ensured that demolition effect.
Description
Technical field：
The utility model adopts overhead caving powder charge dress at the beginning of being related to a kind of fastening means, more particularly to underground mine working face
Put.
Background technology：
Pressed in order to avoid underground mine face roof large area and enormous impact is caused to support, threaten working face personnel
Safety, after underground mine working face installation, promotes after 10m or so, Deephole pre-splitting blasting is carried out in the range of eye cutting, destroy
The integrality of top plate, makes it be caving as early as possible；
Overhead caving is premised on the integrality for destroying top plate, to implement effective control to top plate, it is caving as early as possible, by force
During caving construction processed, tier hole is bored obliquely in top plate, and continuous coupled mode powder charge is then used in blasthole, and use is led
Quick-fried rope connects each pack, aperture filling, so that pack shifts bottom hole onto, and loads real.
General, in order to which powder charge is convenient, frequently with powder charge pvc pipe powder charge bag in practice, it then will be equipped with the powder charge of pack
Pvc pipe is loaded into blasthole, is connected between adjacent powder charge pvc pipe using outer pipe collar, still, has following lack using outer pipe collar
Point：
First, using outer pipe collar, the easy slide downward of pack into blasthole in powder charge fashionable dress medicine pvc pipe adds dress
Medicine difficulty, and explosive easily concentrates on middle and lower part, reduces bottom hole degree of packing, reduces demolition effect.
Second, using outer pipe collar, what primacord easily bent and caused in junction when powder charge pvc pipe is attached leads
Quick-fried rope damage, influences explosive initiation, or even causes to miss-fire, and influences Detonation Initiation Effect.
Utility model content：
In order to solve the problem of existing pvc pipe is connected generation with outer pipe collar, the purpose of this utility model is to provide a kind of
Overhead caving powder charge pvc pipe fastening means is adopted at the beginning of the underground mine working face for facilitating powder charge and detonation.
The purpose of this utility model is implemented by following technical scheme, and overhead caving powder charge PVC is adopted at the beginning of underground mine working face
Pipe fastening means, it includes being equipped with grafting corresponding with the mouth of pipe of powder charge pvc pipe on pipe collar, the two ends port of the pipe collar
The chuck of annular is fixed with groove, the middle part inwall of the pipe collar, the chuck can be to loaded on the medicine in the powder charge pvc pipe
Bag carries out effectively spacing.
Further, through hole is offered on the middle part tube wall of the pipe collar.
Advantage of the present utility model：
First, powder charge pvc pipe is connected by the utility model in the utility model, it is to avoid primacord is in junction because curved
Qu Zaocheng damage, it is ensured that Detonation Initiation Effect.
Second, inserting groove corresponding with the mouth of pipe of powder charge pvc pipe is equipped with the two ends port of pipe collar in the utility model,
In powder charge, due to the inhibition of the pipe collar mouth of pipe, pack can not glide, reduce in powder charge difficulty, hole degree of packing it is big and
Uniformly, it is ensured that demolition effect.

Embodiment：
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment 1：
Overhead caving powder charge pvc pipe fastening means is adopted at the beginning of underground mine working face, it includes pipe collar 1, the two ends end of pipe collar 1
The chuck that annular is fixed with inserting groove 2 corresponding with the mouth of pipe of powder charge pvc pipe 4, the middle part inwall of pipe collar 1 is equipped with mouth
7, chuck 7 can be effectively spacing to being carried out loaded on the pack 5 in powder charge pvc pipe 4, and through hole is offered on the middle part tube wall of pipe collar 1
8。
The quantity of powder charge pvc pipe 4 is needed by the depth calculation of blasthole first, then by priming system, the and of powder charge pvc pipe 4
Pipe collar 1 is transported to underground Qiang Fang places；
Preliminary charging work then is carried out in strong place of putting, pack 5 is fitted into powder charge pvc pipe 4, adjacent powder charge pvc pipe 4
Between leave a pipe collar 1, each pack 5 is connected by primacord 6, and primacord 6 is passed from any one through hole 8, preliminary dress
Structure is as shown in Figure 3 after medicine；
Charging work is finally carried out, the powder charge pvc pipe 4 for installing pack 5 is sequentially loaded into blasthole, in powder charge process,
Adjacent powder charge pvc pipe 4 is clogged aperture padding 3 by the grafting of pipe collar 1, completes charging work, and the structure after powder charge is as schemed
Shown in 4-6.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
