Theory and Application of Rock Burst Prevention Based on Rigid-flexible Integrated Support with Energy Absorbing

Abstract

Based on the theory of stress control for rock burst prevention, rigid-flexible integrated support with energy absorbing was found. In this paper, we tested between flexible yield support and rigid-flexible integrated support with energy absorbing. The results showed that the frequency of rock burst occurrence and the intensity were both declined. The extent of damage to roadway, machines and workers were effectively avoid in several seriously rock bursts with high energy released in Yuejin coal mine, consequently, no casualties and no effect produce occurred when rock burst happened.
