摘　　要：为科学预测刘楼铜铁(金)矿地下开采对地表道路、水闸和民房等建构筑物的安全影响,根据矿山设计资料及开采现状,采用FLAC^(3D)数值模拟软件,对矿山开采过程进行模拟分析,得出了矿山开采结束后地表位移分布情况和位移值。在数值模拟得到的位移数据基础上,通过变形计算公式,得出了矿区地表倾斜、曲率和水平变形值,并绘制了地表变形等值线云图。计算结果表明:矿山开采结束后地表产生的最大倾斜值为0.26 mm/m,最大曲率值为0.04×10^(-3) mm/m,最大水平变形值为0.26 mm/m,小于地表建构筑物的允许变形值,满足相关规范要求,研究结果可以为保障矿山后续开采过程中地表建构筑物安全提供理论依据。In order to scientifically predict the safety impact of underground mining of Liulou copper iron(gold)mine on surface roads,sluice gates,houses and other structures,according to the mine design data and mining status,the FLAC^(3D) numerical simulation software was used to simulate and analyze the mining process,the surface displacement distribution and displacement value after the mining is finished are obtained.Based on the displacement data obtained by numerical simulation,through the deformation calculation formula,the surface inclination,curvature and horizontal deformation values of the mining area are obtained,and the contour cloud map of the surface deformation is drawn.The calculation results show that the maximum inclination value of the surface after mining is 0.26 mm/m,the maximum curvature value is 0.04×10^(-3) mm/m,and the maximum horizontal deformation value is 0.26 mm/m,which is less than the allowable deformation value of the surface structures.The research results can provide a theoretical basis for ensuring the safety of surface structures in the subsequent mining process of the mine.
