摘　　要：为了确定永平铜矿南部-100m中段近地表盘区二步骤采场回采过程中,嗣后胶结充填的作用及其对岩移的影响,首先基于嗣后充填岩移理论进行了初步分析和计算,然后基于AutoCAD、3DMine等软件建立了开采区域的三维可视化模型,并进一步采用3DEC对盘区二步骤采场采-充全过程进行了模拟和对比分析。结果表明:嗣后胶结充填能够有效控制二步骤采场回采后的岩层移动变形大小及范围,充填后岩层移动角得到明显改善,采动影响范围显著减小,对地表露天坑不构成安全威胁。In order to determine the function of subsequent cemented filling and its influence on the strata movement during the near-surface mining of panel second-step stopes in Yongping Copper Mine, firstly, the preliminary calculation and analysis were carried on based on strata movement theories of subsequent filling, then a 3D visualization model of mining area was established by AutoCAD and 3DMine. Furthermore, the whole process of mining and filling in panel second-step stopes was simulated and analyzed with 3DEC. The results showed that subsequent cemented filling can ef- fectively control the strata movement range and deformation, the displacement angle of strata was significantly improved, and the mining influence scope was reduced evidently, which posed little threat on the safety of open-pit.
