摘要
采用现场实测、相似模拟实验以及离散元模拟相结合的综合研究方法,对沿倾斜方向采场上覆岩层的运动与破坏进行了系统的研究.证实了剪切滑移区的存在,并按覆岩运动规律与破坏特征对围岩进行了分区.
A systematic investigation of the movement and failure of overlying rocks in workings is made by site observation,in lab simulation test with equivalent materials and discrete element method.The existence of a shear slip zone is proved,and the overlying strata are divided into different zones according to the rules of strata movement and characteristics of rock failure.
