Abstract

Mine rescue cabin is an important emergency equipment to protect coal miners in gas and coal dust explosion accidents. The rescue cabin body needs to be able to resist the impact of shock waves and rocks, and has excellent heat insulation performance. In general, the design of the mine rescue cabin is to increase the thickness of components or optimize the structure of the rescue cabin. Research performance has been developed and optimized to a bottleneck. In this paper, negative Poisson's ratio material is used to fill the interlayer of the mine rescue cabin. Make use of its light, heat insulation, vibration isolation and excellent impact resistance characteristics. Improve the impact resistance and heat insulation capacity of the overall rescue cabin. The superior safety performance of negative Poisson's ratio filled mine rescue capsule was verified through explosion transient thermal analysis, thermal coupled impact performance analysis and impact response analysis.

Key words
