摘　　要：为更好揭示地下开采对地表构筑物的影响,针对安徽某硫金矿房柱法开采,采用FLAC3D有限元数值分析软件,模拟计算了+5 m以上矿体回采结束后地表位移,实现了对矿区移动带内保护对象区域及位移变化明显区域的变形值计算分析。模拟结果表明:工区地表最大变形及曲率出现在水泥仓、办公楼和泵房所圈范围内,地表位移总体满足安全要求,相关研究手段为同类矿山提供良好借鉴。To better reveal the impact of underground mining on surface structures,this paper focuses on the room and pillar mining meth-od of sulfur gold mine in Anhui.The FLAC3D was used to simulate and calculate the surface displacement after mining of ore bodies above+5 m.The deformation value calculation and analysis of the protected object area and the area with obvious displacement changes within the mining area movement zone were achieved.The simulation results show that the maximum surface deformation and curvature of work area occur within the range of cement silos,office buildings,and pump rooms.The overall surface displacement meets safety requirements,and relevant research methods pro-vide good reference for similar mines.
