Abstract

The utility model discloses a hole-by-hole blasting circuit, wherein each blast hole is filled by a detonation delay detonator. Each row of blast holes is connected for forming a set through explosion propagation delay detonators I. After the sets of blast holes are connected through explosion propagation delay detonators II. According to the hole-by-hole blasting circuit of the utility model, each row of blast holes is designed to a set. The sets of blast holes are successively blasted through delay detonation. The blast holes in each set are successively blasted through delay detonation, thereby realizing hole-to-hole blasting. Therefore, the hole-by-hole blasting circuit has the following advantages: reducing vibration generated in explosion, satisfying safety requirement of the buildings at the periphery of the exploded area, and simultaneously improving explosion quality remarkably.

Description

The hole-by-hole initiation networking

Technical field

The utility model relates to a kind of blasting circuit, is specifically related to a kind of hole-by-hole initiation networking.

Background technology

The short-delay blasting of many rounds generally is meant the explosion of detonating blanking time with Millisecond between each row of many rounds; Compare with the single row of holes volley that the past generally uses, the short-delay blasting of many rounds have improve blasting quality, improve demolition effect, burst size is big and reduce advantage such as earthquake sheet.

But when near the blast area building being arranged, the vibration that produces when adopting common short-delay blasting can have influence on the stability of fabric structure, need improve detonation mode and reduce vibration, satisfies the building safety demand.

Summary of the invention

In view of this, the utility model provides a kind of hole-by-hole initiation networking, can reduce the vibration that explosion produces, and satisfies near the demand for security of building the blast area.

The hole-by-hole initiation networking of the utility model, the delay detonator that detonates all is equipped with in each big gun hole, and each row big gun hole is one group through the series connection of propagation of explosion delay detonator I, connects initiation ends through propagation of explosion delay detonator II series connection back between each group.

Further, the said delay detonator that detonates is high section delay detonator, and said propagation of explosion delay detonator I and propagation of explosion delay detonator II are low section delay detonator;

Further, the said delay detonator that detonates is ten sections detonators of millisecond, and said propagation of explosion delay detonator I is five sections detonators of millisecond, and said propagation of explosion delay detonator II is two sections detonators of millisecond;

Further, the line in said each row big gun hole and step bench crest are oblique;

Further, said initiation ends is positioned at big gun district one side.

The beneficial effect of the utility model is: it is one group that the blasting circuit of the utility model is designed to each row big gun hole, respectively delays time successively between group and detonates, and also delays time successively between each hole in the group and detonates; Realized hole-by-hole initiation; Therefore, the utility model has reduced the vibration that explosion produces, and has satisfied near the demand for security of building the blast area; Simultaneously, blasting quality has also had obvious improvement.

Description of drawings

For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.

Fig. 1 is the structural representation of the utility model; As shown in the figure, the hole-by-hole initiation networking of the utility model, the delay detonator that detonates all is equipped with in each big gun hole 1; Each row big gun hole 1 is one group through 2 series connection of propagation of explosion delay detonator I, connects initiation ends 4 through propagation of explosion delay detonator II 3 series connection backs between each group.

In the present embodiment, the said delay detonator that detonates is high section delay detonator, and said propagation of explosion delay detonator I 2 is low section delay detonator with propagation of explosion delay detonator II 3; High section delay detonator in the hole, the section delay detonator is hanged down on the face of land, can effectively avoid detonator to be destroyed by the slungshot of quick-fried big gun hole generation earlier, guarantees the quick-fried property of standard at networking.

In the present embodiment, the said delay detonator that detonates is ten sections detonators of millisecond, and said propagation of explosion delay detonator I 2 is five sections detonators of millisecond, and said propagation of explosion delay detonator II 3 is two sections detonators of millisecond.

In the present embodiment, the line and the step bench crest in said each row big gun hole 1 are oblique; Oblique line detonates and helps improving blasting quality.

In the present embodiment, said initiation ends 4 is positioned at big gun district one side.

When the utility model detonates; From initiation ends 4 beginning, because the time-lag action of propagation of explosion delay detonator II 3, respectively organize big gun hole 1 from right to left and delay time successively and detonate; Because the time-lag action of propagation of explosion delay detonator I 2; In the group also delay time successively and detonate in 1 in each big gun hole, realized hole-by-hole initiation, reduced the vibration that explosion produces.

Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although the preferred embodiment through with reference to the utility model is described the utility model; But those of ordinary skill in the art should be appreciated that and can make various changes to it in form with on the details, and the spirit and the scope of the utility model that does not depart from appended claims and limited.
