摘　　要：某金矿地表岩石移动带内分布有公路、村庄等建(构)筑物,划定的保安矿柱资源量占总设计利用资源量的55.5%,严重影响了项目的开发效益。为确保岩石移动范围内建(构)筑物的安全,最大限度地回收矿石资源,采用MIDAS和3DMine联合建模、FLAC^(3D)计算、Tecplot后处理的方法,分析了地下开采对地表建(构)筑的影响。经计算,地表沉降、水平位移、曲率均满足设计规范的要求,为该矿最大限度地回收资源提供了依据。Roads,villages and other buildings(structures)are distributed in the surface rock move⁃ment zone of a gold mine.The delineated security pillar resources account for 55.5%of the total designed utilization resources,which seriously affects the development benefits of the project.In order to ensure the safety of structures within the range of rock movement and maximize the recovery of ore resources,MIDAS and 3DMine combined modeling,FLAC^(3D) calculation and Tecplot post-processing were used to analyze the influence of underground mining on surface buildings(structures).After calculation,the surface subsid⁃ence,horizontal displacement and curvature all meet the requirements of the design specification,which provides a basis for the mine to maximize the recovery of resources.
