摘    要:地下金属矿山深部开采引起地表移动变形的预测是一项技术难题。通过对某矿区工程地质特点和开采技术条件进行深入了解,建立了具有较高仿真度的三维深部开采模型,并对矿区的开采进行了系统的模拟研究。通过开采三期工程(1 337~1 237 m)时地表下沉的计算值与现场GPS实测值之间的吻合,较准确地预测出四期工程深部开采过程中的各阶段移动角及地表移动变形范围,为该矿山深部开采地下工程的布置及地表移动范围的设计提供了依据。

关 键 词:深部开采  地表移动变形  移动角  FLAC3D  数值模拟

Abstract:It is difficult to predict surface movement deformation caused by deep mining of underground metal mines.By analysis on engineering geological characteristics and mining conditions in one mining area,the 3D model of deep mining with high simulation degree has been established,and the exploration of mining area has been simulated systematically.After the third phase of excavation,the calculated values of surface subsidence are consistent with that of GPS measured.Then the displacement angles and ground defor...
Keywords:deep mining  surface movement deformation  displacement angles  FLAC3D  numerical simulation
