Abstract

The invention discloses an explosion test simulation experiment device for an explosion-proof sealing wall. The invention relates to the technical field of explosion-proof sealing wall simulation. Thedevice comprises a coal mine tunnel simulation pipeline and a central controller; the central controller is electrically connected with a computer; the inner side wall of the coal mine tunnel simulation pipeline is a wall surface of a similar material, and a dynamic stress-strain tester I, a pressure sensor I and a temperature sensor I are mounted in the coal mine tunnel simulation pipeline. According to the invention, the problem of testing the mechanical property of an explosion-proof sealing wall under the condition of dynamic load is solved. Except for a mechanical property test, connecting branch pipelines and explosion-proof sealing wall positions can be increased according to the environment of an on-site roadway to simulate complicated roadway explosion conditions on site, a proper explosion-proof sealing wall construction position can be designed, and meanwhile, the safety performance of the existing explosion-proof sealing wall can be evaluated, so that the on-site requirements are met.

Description

technical field [0001] The invention relates to the field of explosion-proof airtight wall simulation technology, in particular to an explosion test simulation experiment device for an explosion-proof airtight wall. Background technique [0002] The underground production conditions of my country's coal mines are complex and the geological conditions are changeable. With the increase of mining intensity and depth, the gas emission in coal mines is increasing, and the spontaneous combustion of coal seams and the gas explosion accidents caused by them are increasing. The gas explosion accident is one of the important disasters that endanger the safe production of coal mines. Once the explosion occurs, the damage will be huge, and it will also cause the coal dust accumulated in the roadway to rise and cause a secondary explosion, causing more gas explosion disasters. In order to prevent gas explosions, spontaneous combustion of coal seams, or diffusion of harmful gases from aff...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing explosion-proof airtight walls usually use static load uniaxial fracturing test or numerical simulation to test their compressive strength when designing and constructing the process, but this method cannot truly reflect the mechanics of the explosion-proof airtight wall during the gas explosion process. Performance and destruction mechanism, so in the past there have been many major gas explosion accidents where the explosion-proof airtight wall failed

In order to measure these performances more realistically, it is best to test the impact dynamic load on the airtight wall by means of gas explosion, but such an experimental test is not allowed under field conditions, so an explosion-proof airtight wall is needed Explosion test simulation experimental device
