摘　　要：通过建立相似材料模拟实验,对倾斜煤层开采引起的上覆岩层移动进行了系统地全面地观测研究。利用首次观测数据和开采结束稳定后数据,定性与定量分析了岩层内部各点移动矢量,得出测点移动矢量图。分析不同区域内6个观测点的动态运动轨迹,得到了详细的移动轨迹。对岩体内部巷道工程的损害及治理具有指导意义。Strata movement of surrounding rock induced by inclined coal-seam mining was observed by analog simulation.Movement vector of every point in rock was analyzed qualitatively and quantitatively and point movement vector map was obtained.Detailed movement tracks were obtained by analyzing dynamical movement tracks of 6 observation points.This would provide reference for preventing roadway failure in rock.
