Abstract
The utility model relates to a hole bottom detonating device of two function holes, used for mine blasting operation. The detonating device comprises a cartridge case, safety helmets and a support wing arranged on the bottom of the cartridge case. An auxiliary charge is arranged in the cartridge case on the bottom, a main charge is arranged on the upper part, and a cover is arranged on the top part. The utility model is characterized in that two detonator holes are arranged on the main charge, two detonating cord holes are correspondingly arranged on the cover, and two detonating cord grooves are pressed on the outer wall of the cartridge case. The occurrence rate of blown out shot is reduced to a maximum extent. The detonating device is safe and reliable to use. In general condition, accident rate can be reduced to zero. The utility model is broadly used for deep hole detonation in all kinds of mine blasting operation.
Description
(1) technical field: the utility model relates to a kind of difunctional hole hole base initiation tool that the mine blasting operation is used.
(2) background technology: when the mining ore of down-hole, traditional operating type need above mine radial get out a lot of in dark blast hole, in blast hole, fill explosive, lead quick-fried groove by being equipped with at the bottom of aperture to the hole; By at the bottom of aperture to the hole, detonate one by one from outside to inside, this mode shortcoming is bigger when detonating, and open wiring destroys seriously after the explosion, and ore boulder yield height needs second-time breakage.Detonation tool at the bottom of generally adopting one to place the medium-length hole hole is now closed under the state by medium-length hole hole underseal and to detonate from inside to outside.It is made up of safety cap, gland, shell case cover, support fins, main medicine column, auxiliary post etc., mainly develop at the medium-length hole hole base initiation of mine, down-hole, can be widely used in the hole base initiation of all kinds of mine blasting operation medium-length holes, also can replace the detonate explosive of arbitrary type of igniting primer in all kinds of quick-fried miner's journeys, realize detonating of arbitrary position in the full big gun hole.Particularly in down-hole mine blasting operation sublevel caving method without sill pillar, adopt powder type explosive to calm the anger and carry the supporting use of filling hole base initiation tool to implement the hole base initiation, demolition effect is splendid.
Hole base initiation tool product generally all is to adopt the simple function hole, uses single cap sensitive but at present.Use the result to show through users, there is following defective in this product:
The detonation tool grain density is bigger, and sensitivity is on the low side.Owing to use single functional hole, in case the detonator generation quality problems of igniting etc. will produce miso-fire, the success rate of therefore detonating is subjected to factor affecting such as detonator quality, grain density bigger, and it is stable inadequately to detonate.As miso-fire takes place, and then need to draw the hole, the product that miss-fires is cleared up, not only waste time and energy, main is to be unfavorable for job safety.
(3) summary of the invention: the purpose of this utility model is exactly that the hole base initiation tool that will solve existing simple function hole is easy to generate miso-fire, and grain density is big, and the stable inadequately problem of detonating provides a kind of difunctional hole hole base initiation tool.
Concrete scheme of the present utility model is: improve at existing hole base initiation tool, it has the shell case cover, safety cap, and be loaded on the support fins that shell case overlaps the bottom, in the shell case cover, the auxiliary post is equipped with in the bottom, main medicine column is equipped with on top, and gland is placed at the top, it is characterized in that: offer two detonator holes in main medicine column, correspondence has two mooring hawses on gland, and is suppressed with two dragline grooves at shell case cover outer wall.
The filler of major and minor powder column described in the utility model is conspired and is 1.25-1.35g/cm3.
The utility model can effectively reduce and leaks a jam, buried via hole rate, reduces the generation of miso-fire to greatest extent, and is safe and reliable.Generally speaking, accident rate can reduce to zero, can effectively improve the open wiring serviceability rate simultaneously, and reduction air-shock wave that can be by a relatively large margin is to the destruction of mine structures.
(4) description of drawings:
Fig. 1 is a main cutaway view of the present utility model;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: 1-safety cap, 2-gland, 3-mooring hawse, 4-shell case cover, 5-main medicine column, 6-detonator hole, 7-auxiliary post, 8-support fins, 9,10-dragline groove.
(5) specific embodiment:
Referring to Fig. 1, Fig. 2, the utlity model has the basic structure of plain bore base initiation tool, include shell case cover 4, safety cap 1, and be loaded on the support fins 8 that shell case overlaps 4 bottoms, in shell case cover 4, auxiliary post 7 is equipped with in the bottom, and main medicine column 5 is equipped with on top, gland 2 is placed at the top, it is characterized in that: in main medicine column 5, offer two detonator holes 6, corresponding on gland 2, have two mooring hawses 3, and overlap 4 outer walls at shell case and be suppressed with two dragline grooves 9,10.
Major and minor powder column 5 and 7 packing density are designed to 1.25-1.35g/cm in the utility model
3Main medicine column weight is designed to 85-99g, and auxiliary post weight is designed to 24-28g.
When the utility model uses, open safety cap, in two detonator holes 6, lay two detonators respectively, and adopt two fuse cords respectively two mooring hawses 3 from the gland draw by two dragline grooves 9 and 10 of shell case cover outer wall again.
Claims (2)
1. difunctional hole hole base initiation tool, it has the shell case cover, safety cap, and be loaded on the support fins that shell case overlaps the bottom, in the shell case cover, the auxiliary post is equipped with in the bottom, main medicine column is equipped with on top, and gland is placed at the top, it is characterized in that: offer two detonator holes in main medicine column, correspondence has two mooring hawses on gland, and is suppressed with two dragline grooves at shell case cover outer wall.
2. hole base initiation tool in difunctional hole according to claim 1, it is characterized in that: the packing density of described major and minor powder column is 1.25-1.35g/cm
