Study on Application of the Mine Anti-Impact and Energy-Absorption Device

Abstract:

This article touches on the problem that the shock occurs on support at the time of violent vibration and deformation failure of the surrounding rocks. According to the buckling principle, a thin-walled energy-absorption component is designed with special shape applied to a new roadway anti-impact and energy-absorbing hydraulic support in order to relieve excess load impact and injuring and damage by itself and the traits abdicating deformation process and when impact of surrounding rock occurring suddenly, thus preventing support system from the serious damage caused by rock burst. In the theory, simplified energy-absorbing component capacity and energy-absorption formula are obtained by the theory analysis, the effect of energy-absorption curve and the buckling deformation mode are obtained in the quasi-static compression test, results are almost the same with simulation and provide certain reference for the optimization design of support.
