Abstract
The utility model relates to a shock proof explosive bag. One side of the explosive bag is provided with a shock absorbing layer; a ratio of cross-sectional areas of the shock absorbing layer and the explosive is no larger than 1. The shape of the utility model and the ratio of the cross-sectional areas of the shock absorbing layer and the explosive can be specifically determined according to rock strength and structural characteristics. One side of the explosive bag is provided with the shock absorbing layer, the shock absorbing layer of the explosive bag is arranged face to an excavating edge line, and as a result, the utility model can reduce damage to an excavating surface during detonating; simultaneously, the periphery of the excavating edge line is detonated together with the center. The utility model has the advantages of convenient operation, low explosion cost and low risk. The utility model can be used for excavating tunnels and slopes, and can also be used for controlling the explosion for removing buildings.
Description
Technical field
The utility model relates to a kind of blasting technique, particularly a kind of blasting charge.
Background technology
During the explosion of cubic meter of stone excavation, not only require to explode to remove predetermined rock mass, and the excavation face of the rock mass that needs protection.The protection blasting technique that adopts mainly contains presplit blasting and smooth blasting dual mode at present.Wherein presplit blasting is the pre-ceasma at place, excavation sideline that detonates earlier, and then carries out the excavation area explosion; Smooth blasting is first in the excavation area explosion, the quick-fried then quick-fried layer of the light that shields that removes.The slit vibration damping protection rock mass that presplit blasting utilizes presplitting to produce, because it is the fracture width that forms is limited, not too obvious to the protective effect of rock; Smooth blasting is protected protected rock mass by reserving the rock mass protective cover, because the resistance that rock produces still has certain damage to the excavation face less than blast action power when detonating; Simultaneously, blasting time is carried out segment blast because top two kinds of protection blasting methods all need stagger, and has not only increased blasting cost and difficulty, has also increased the explosion risk simultaneously.
Summary of the invention
The purpose of this utility model is in order to provide a kind of to the little vibrationproof blasting charge of excavation sideline degree of injury.
The purpose of this utility model can realize by following measure:
A kind of vibrationproof blasting charge comprises the blasting charge, is provided with shock absorption layer in a side of the described blasting charge.
Described shock absorption layer is not more than 1 with the ratio of the sectional area of explosive.
Described shock absorption layer is the low mold materials that becomes.
The utility model compared with prior art has the following advantages:
1, the utility model has reduced the damage to the excavation face owing to the side at the blasting charge is provided with shock absorption layer.
2, the utility model need not adopt the delay detonator because the blast hole in the excavation area detonates simultaneously, and is easy and simple to handle, reduced blasting cost and risk.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model
1-shock absorption layer 2-explosive
The specific embodiment
A kind of absorbing blasting charge shown in Figure 1 is that the side at explosive 2 is provided with shock absorption layer 1; In order to make demolition effect good, and do not damage the excavation sideline, the ratio of the sectional area of shock absorption layer 1 and explosive 2 is not more than 1; Shock absorption layer 1 can be a foam class material.
The utility model can be used for the excavation of cavern, side slope, also can be used for the controlled blasting of demolishing buildings.Shape of the present utility model and shock absorption layer should specifically be determined according to the intensity and the structure characteristics of rock mass of rock with the ratio of the sectional area of explosive.
Claims (3)
1, a kind of vibrationproof explosion cartridge bag comprises the blasting charge, it is characterized in that being provided with shock absorption layer in a side of the described blasting charge.
2, vibrationproof explosion cartridge bag as claimed in claim 1 is characterized in that the described shock absorption layer and the ratio of the sectional area of explosive are not more than 1.
3, vibrationproof explosion cartridge bag as claimed in claim 1 is characterized in that described shock absorption layer is the low mold materials that becomes.
