| 摘 要： | 针对深部巷道岩爆现象,结合华丰煤矿深部开采的冲击地压问题,采用FLAC-Dynamic进行了深部巷道岩爆动力学计算分析.计算结果表明,发生岩爆时,巷道围岩的速度曲线和加速度曲线出现突变.在水平构造应力的作用下,巷道可能岩爆的过程是先从巷道的两帮开始,然后迅速扩展到巷道的顶、底板的过程.

| Abstract: | 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. |
