Abstract
A rock blasting splitter capable of lengthening the distance between two adjacent blast holes relates to a rock blasting splitter tube and aims to resolve the problem that explosive blasting energy in the existing rock blasting splitter tube can not be utilized sufficiently so that the distance between each two adjacent blast holes on rocks is short. The rock blasting splitter is characterized in that opening ends of two energy concentration partitions with V-shaped sections are opposite to each other, the two energy concentration partitions are arranged between two buffer medium partitions, cavities formed by the inner wall of a round tube between the two buffer medium partitions and energy concentration partitions with the V-shaped sections corresponding to the buffer medium partitions are energy concentration spaces, the taper angle of the energy concentration partitions with the V-shaped sections ranges from 60 degrees to 63 degrees, the distance between the two buffer medium partitions is 0.23-0.25 time of the diameter of the round tube, and a buffer medium is filled between each buffer medium partition and the round tube. When in use of the rock blasting splitter, the distance between the two adjacent blast holes can be lengthened to 500-530 mm.
Description
Technical field
The utility model relates to a kind of rock blasting splitter, is particularly useful for the shaping blasting to rock, relates to the blasting technique field.
Background technology
With existing rock blasting split tube exploitation stone material, can prevent from that stone material from causing to shatter when explosion, and molding effect is also better, can be when explosion along the direction cracking of setting.But it also has the following disadvantages, energy during explosive charge in the rock blasting splitter is not also utilized more fully, cause on the rock distance between adjacent two blast holes can not elongate to longer length, that is to say that what need be in the rock upper edge for the treatment of explosion same straight line needed that uniform cutting has a comparatively dense is used to install rock blasting splitting tubulature
Blast hole (during with existing rock blasting split tube exploitation stone material, distance between adjacent two blast holes is 320 ㎜～350 ㎜, otherwise molding effect is poor), so not only increased the rock drilling workload, must need more rock blasting splitter, influence operating efficiency, caused waste.
The utility model content
The purpose of this utility model provides a kind of rock blasting splitter that makes distance lengthening between adjacent two blast holes, energy when solving the explosive charge in the existing rock blasting split tube is not utilized more fully, cause the distance between adjacent two blast holes less (blast hole comparatively dense) on the rock, so not only increased the rock drilling workload, must need more rock blasting splitter, influence operating efficiency, caused the problem of waste.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the rock blasting splitter of distance lengthening between adjacent two blast holes that makes described in the utility model comprises pipe and explosive filling pipe, explosive filling pipe centering vertically is arranged in the pipe: described explosive filling pipe is to surround the cylinder that has cavity by the cumulative dividing plate that two buffer medium dividing plates and two cross sections are in the shape of the letter V, two buffer medium dividing plates are set in parallel in the pipe, the opposing setting of openend of the cumulative dividing plate that two cross sections are in the shape of the letter V and the two is between two buffer medium dividing plates, the cavity that surrounds between the cumulative dividing plate that the inwall of the pipe between two buffer medium dividing plates and corresponding cross section are in the shape of the letter V is the cumulative space, the cone angle of the cumulative dividing plate that the cross section is in the shape of the letter V is 60 °～63 °, and the distance between two buffer medium dividing plates is 0.23～0.25 times of pipe diameter; All be filled with buffer medium between each buffer medium dividing plate and the pipe.
The beneficial effects of the utility model are:
Obtain structural parameters after rock blasting splitter described in the utility model is optimized by Test Summary many times: the cone angle of the cumulative dividing plate that the cross section is in the shape of the letter V is 60 °～63 °, distance between two buffer medium dividing plates is 0.23～0.25 times of pipe diameter phi, limit by above-mentioned parameter, the cumulative action that is positioned at the cumulative space of explosive filling pipe both sides of the present utility model is brought into play to best, the shaping blasting energy is increased severely, but also play the effect of determining the presplitting direction.When the explosive charge in the explosive filling pipe, produce jet, itself and big gun hole wall collision back formation stagnation pressure at the symmetrical cone angle place in two cumulative spaces, at first on hole wall, cut out the crack, and then its detonation gas quasi static pressure acts on hole wall, the cutting seam is further enlarged, between two big gun holes, connect.Of the present utility modelly make that the distance lengthening is 500～530 ㎜ between adjacent two blast holes by what above-mentioned parameter limited, and good forming effect, explosion face quality is higher, satisfies instructions for use.And when adopting existing rock blasting split tube to implement explosion on the rock of same nature and will reach better molding effect the time, distance is less than or equals 320 ㎜～350 ㎜ between adjacent two blast holes.This shows, use of the present utility model, under the prerequisite that guarantees blasting quality,
Can makeTreat distance lengthening between adjacent two blast holes on the rock face of explosion
,So not only reduce the rock drilling workload, increased work efficiency, also saved more rock blasting splitter, greatly reduced the processing cost of rock blasting.
