Abstract
The utility model discloses a detonating device for simulating the tunneling of a vertical shaft with a square cross section. The detonating device comprises a steel cylinder, wherein the wall thickness of the steel cylinder is no less than 3mm and the cross section of the steel cylinder is square. A solidified body for simulating rocks in different mechanical properties is poured in the steel cylinder. Simulating blast holes are prefabricated in the solidified body, and electric detonators for simulating an explosive are installed in the simulating blast holes. The proportion of the cross section of the steel cylinder to the actual cross section of the vertical shaft is 1:5. The height of the steel cylinder needs to be two times greater than the depths of the simulating blast holes. When the simulating blast holes are prefabricated, peripheral holes with different intervals can be prefabricated, and different loading structures such as continuous load, intermittent load, coupled load, positive load and negative load can be simulated when the electric detonators are installed, and the detonating sequence can be further simulated. The actual arrangement of the peripheral holes, the loading structures and the detonating sequence can be determined according to effect of simulated explosion, so that the cross-section forming rate of the vertical shaft is increased.

Technical field
The utility model relates to a kind of experimental simulation device for the rock blasting experiment.
Background technology
At present, in mine design, sometimes according to requirement of engineering, be designed to square cross-section, during the shaft sinking of square cross-section, the periphery hole explosion at four angles is difficult to control, once the blasting parameter design is bad, is difficult to produce qualified square cross-section.So, carry out some experiments and just can obtain rational blasting parameter.Because on-the-spot large-scale experiment not only needs to spend substantial contribution, and be subject to the impact of various factors after rock blasting, can't obtain blasting parameter and blasting result accurately, and the modeling experiment not only can be saved substantial contribution, but also the advantage that tool blasting parameter and blasting result easily record, and carry out the qualitative and quantitative analysis.
Therefore, it is very important designing a kind of square cross-section shaft sinking explosion analogue experiment installation.
The utility model content
The purpose of this utility model is for solving the problem of square cross-section shaft sinking explosion simulated experiment, designing a kind of demolition set of simulating the square cross-section shaft sinking.
To achieve these goals, structure of the present utility model is, a kind of simulation square cross-section shaft sinking water level demolition set, it comprises that the section that a wall thickness is not less than 3mm is square steel cylinder, build the solidifying body of the different mechanical property rocks of simulation in steel cylinder, be prefabricated with the artillery simulators hole in solidifying body, the electric cap of Dynamite is installed in the artillery simulators hole; Wherein the ratio of the cross dimensions of steel cylinder and actual shaft section area size is 1:5, and the height of steel cylinder should be greater than 2 times of artillery simulators hole depth.
Good effect of the present utility model is, when prefabricated artillery simulators hole, can precast the periphery hole of different spacing, when being installed, electric cap can simulate different charge constitutions, as continuous charging, spaced loading, coupling charging, forward powder charge, inverse initiation etc., also can simulate firing order.Can determine actual periphery hole layout, charge constitution and firing order according to the effect after model blasting like this, improve the shaft section area shaping rate.
