摘要
Abstract
In order to study the impact of goaf on main shaft of Tushan iron deposit,a 3 D geo-mechanical numerical analysis model has been established by using 3 DMine-Midas GTS-FLAC3D coupling technolo-gy,and the influence of deposit mining on the stability of main shaft has been simulated.The deformation values(inclination value,curvature value,and vertical deformation value),maximum compressive stress,maximum shear stress,maximum vertical displacement,and plastic zone distribution characteristics of the surrounding rock on four simulated monitoring lines of main shaft wall have been studied,the safety and stability of the shaft have been accurately simulated and analyzed.It will provide a new solution approach for the stability research of complex goaf and vertical shaft.关键词
