| 摘 要： | 以程潮铁矿东区为例,通过现场结构面调查、地表及深部岩体变形监测,分析了该区地表及岩体移动变形与结构面的关系。结果表明:程潮铁矿东区地表及岩体移动变形主要受该区复杂的地质条件控制,特别是结构面的影响,变形方向和变形量值均与理论预期不同。NNE、NE向结构面的存在控制着岩体向采空区运动的侧向边界条件,同时导致变形方向的向西偏转,NWW向结构面的松动导致东主井区岩体向采空区的倾倒变形,地表变形在南北剖面上呈三级阶梯分布;西风井相对东西采空区的特殊位置以及NE向结构面的影响使其变形值小于预期,是该区相对安全的主要原因。

| Abstract: | Taking a typical iron mine as the background engineering,the discontinuities of rock mass were revealed by the field geological survey and borehole camera technology;and based on the results of deformation monitoring including the global positioning system(GPS),leveling measurement,fissure extensometer monitoring and borehole deviation surveying,the influence of discontinuities on rock movement and surface deformation caused by underground mining is analyzed.Results obtained indicate that: the special geolo... |
