Numerical simulation of rock burst under depth portion tennel tectonic stess

This article carries on the dynamics computation analysis of the deep roadway rock burst used FLAC-DYNAMIC in view of the phenomena of the deep roadway rock burst and the question of the deep roadway rock burst of Chinese abundant coal mine.The computed result indicates the acceleration curve and the speed curve appears change suddenly in the rock burst.The process of the tunnel rock burst occurs possibly from the tunnel of two groups,then expands rapidly to the tunnel goes against,the ledger wall process under horizontal tectonic stress function.
