摘　　要：为了研究深部采场围岩特性及随生产扰动的运移规律,以林西矿1021-2工作面为研究对象,通过采场围岩的物理机械性质进行取样测试,对深部采场地应力方向、大小进行现场测试,运用仿真模型对采场覆岩运动进行理论研究,得出林西矿深部覆岩运动及矿压显现规律,给巷道支护设计、采面支架选型、顶板支护等矿压治理提供基础性理论依据。In order to study the characteristics of the deep quarry perimeter and the transportation laws with production disturbances,Linxi Mine 1021-2 face was used as the object of study.The physical and mechanical properties of the quarry perimeter were sampled and tested,and the direction and magnitude of the stress in the deep quarry were tested in the field,and the theoretical study of the quarry overburden movement was carried out using the simulation model.It provided the basic theoretical basis for mine pressure management,such as support design,face support selection,and roof support.
