摘　　要：结合湖北省大冶市正兴铁矿的残矿回收工程实践,利用有限元数值分析软件ANSYS,建立矿山三维模型。首先利用有限元软件分析现有采空区的围岩稳定性,在此基础上运用ANSYS Workbench的Design Exploration设计模块,模拟残矿回采过程中不同工况对地下复杂采空区条件下岩体稳定性的影响,将矿柱的回采程度予以量化;同时借助声发射技术对危险区域进行安全监测预警。分析成果能对声发射监测布点提供科学依据,模拟结果对矿山安全生产具有重要的指导意义。Based on the recovering remnant ore engineering practice of Zhengxing Iron Mine in Hubei Daye, the finite element analysis software ANSYS is used to build the mine 3D model. On the basis of the finite element analysis of the sta- bility of surrounding rock, combining with Design Exploration design module of ANSYS Workbench, simulating the influence of rock mass stability of complicated conditions during the process of recovering remnant, and quantified the extent of pillar mining. At the same time, launching the safety monitoring and early warning of dangerous region by means of acoustic emis- sion technique, analysis results can provide scientific basis to acoustic emission monitoring stationing. The simulation results are instructively important for safe production in mines.
