摘要
为研究动载方向对于诱发巷道冲击矿压的影响,运用FLAC2D中的动态模块,研究分析了不同动载方向下震动波在巷道顶板传播的速度、位移和加速度的变化规律以及震动波引发的巷道顶、底板和左、右帮速度和加速度变化规律,为预防冲击矿压提出相应技术措施。
In order to study on effect of roadway burst induced by dynamic disturbance at different directions, we discussed the variation law of velocity, displacement and acceleration on the roadway roof caused by vibration wave and the variation law of velocity and accel- eration on the road roof and floor and the roadway~ sides caused by vibration wave under different dynamic directions by using the dy- namic module of FLACaD program, and it provided technical measures for the prevention of rock burst.
