Abstract

The invention discloses a method for detecting the anti-explosion performance of a mining mobile rescue capsule, and relates to the technical field of mine emergent rescue, aiming at solving the problem that in the existing anti-explosion performance detection of the mining mobile rescue capsule, the complicated soil-fluid coupling effect between gas explosion shock wave and the structure of the rescue capsule is not considered. The method for detecting the anti-explosion performance of the mining mobile rescue capsule comprises the following steps: 1, establishing a three-dimensional finite element model of a shell of the mining mobile rescue capsule; 2, carrying out numerical simulation in real underground roadway environment or gas explosion flow field environment; 3, determining boundary conditions; 4, determining the materials of all components of the mining mobile rescue capsule; 5, carrying out numerical simulation in the gas explosion flow field environment; 6, analyzing the dynamic response of the mining mobile rescue capsule under a gas explosion shock wave load effect by a soil-fluid coupling method. The method can be applied to the technical field of mine emergent rescue.

Description

technical field [0001] The invention relates to the technical field of mine emergency rescue, in particular to a method for detecting the anti-explosion performance of a mine-used movable rescue cabin. Background technique [0002] Coal is a traditional and widely used important energy source. my country is the country with the largest coal consumption in the world, and our country is also a large coal-producing country. With the continuous increase of the mining depth and scope of coal mines, the prominent danger of coal mines is also becoming more and more serious. It is getting more and more serious, and the safety production situation in coal mines is becoming increasingly severe. Once a mining accident occurs, protecting the lives of miners has become a top priority. [0003] The mine movable rescue cabin is an effective measure to provide miners with a stable, reliable and well-guaranteed living space in a catastrophic environment when a mine disaster occurs, and to min...
