Abstract
A kind of blasting hole radial direction Uncoincided charge connector, including top flap, inner bag, shell and bottom baffle, it is characterized in that, described inner bag is located at enclosure, and inner bag is connected by top flap, bottom baffle with shell and forms airspace chamber, and the cavity of top flap, bottom baffle and inner bag communicates composition powder charge chamber, top flap central opening is medicine containing opening, its bore is equal with powder charge chamber, and bottom baffle central opening is bottom outlet, and its bore is less than powder charge chamber.Blasting hole radial direction Uncoincided charge connector of the present utility model, blasthole charging height can not only be lifted, make blast fragmentation size more uniform, the boulder yield of reduction filling section, and airspace section two sections powder column can be made to link together, reduce the usage amount of detonator, reduce explosive specific charge and construction cost, have constructing operation easy simultaneously, it is wide using scope, it can be suitably used for vertical hole, tilt blasthole and horizontal blasthole.
Description
Technical field
The utility model is related to a kind of blast charging device, and more particularly to a kind of blasting hole radial direction Uncoincided charge connects
Connect device.
Blast charging spacer and a kind of powder charge connector, the function not only with blast charging interval effectively improve dress
Medicine height, improves demolition effect, and can break traditions, and powder charge section above and below outside spacer is connected, reaches continuous dress
The purpose of medicine, reduces the quantity of igniting primer, saves detonator use cost.
Background technology
At present, hole Blasting In Open-pit Mines reduce explosive specific charge to reduce boulder yield, cost-effective, improve demolition effect, improve
Benefit, frequently with spaced loading technology, especially air-decking technique.Only it is continuous using more air-spacer
Powder charge section is spaced apart with air section, is generally divided into 1~2 airspace section, boulder yield can be reduced to a certain extent, is dropped
Low unit consumption.But when using multiple airspaces section to carry out spaced loading, each powder charge section must at least fill 1 hair detonator as rising
Quick-fried pack, this causes detonator use cost to significantly improve, and operates complex.So that most of work orders in hole Blasting In Open-pit Mines
Position is unwilling to use, so existing air-spacer, which can not play it completely, improves the effect of demolition effect.
The content of the invention
It is high, easy to operate and applicable that the purpose of this utility model is just to provide a kind of air storing cavity good airproof performance, support strength
The low blasting hole radial direction Uncoincided charge connector of in extensive range, cost.
Blasting hole radial direction Uncoincided charge connector of the present utility model, including top flap, inner bag, shell and bottom
Baffle plate, it is characterised in that described inner bag is located at enclosure, inner bag is connected by top flap, bottom baffle with shell and formed
Airspace chamber, the cavity of top flap, bottom baffle and inner bag communicates composition powder charge chamber, and top flap central opening is dress
Medicine mouthful, its bore is equal with powder charge chamber, and bottom baffle central opening is bottom outlet, and its bore is less than powder charge chamber.
Blasting hole radial direction Uncoincided charge connector of the present utility model, in use, whole connector is positioned over quick-fried
Between broken blasthole two sections explosive, powder charge intracavitary fills up explosive and forms powder column, or two connectors are serially connected, and makes
Powder column is connected, and inner bag plays a supportive role simultaneously with shell.
Blasting hole radial direction Uncoincided charge connector of the present utility model, can not only lift blasthole charging height, make
Blast fragmentation size is more uniform, the boulder yield of reduction filling section, and airspace section two sections powder column can be made to be connected to one
Rise, reduce the usage amount of detonator, reduction explosive specific charge and construction cost, while have constructing operation easy, energy wide using scope
Suitable for vertical hole, tilt blasthole and horizontal blasthole.
