摘　　要：依据程潮铁矿西区的地表水平位移、沉降位移和运输巷道关键测点的变形监测成果,对运输巷道区域地表变形规律及变形机理进行了分析研究。结果表明:运输巷道目前位于倾倒区,深部岩体变形处于弯曲变形阶段,变形趋势为向采空区的整体倾倒,该区域变形不大,以稳定变形为主;随着采矿工作在深度和平面上的拓展,深部岩体有可能形成弯曲折断面,进入倾倒滑移区,地表变形以快速为主。其成果对程潮铁矿西区运输巷道的安全运营及类似工程具有重要的指导意义。According to horizontal displacement and vertical displacement in the west of Chengchao iron mine,as well as the deformation monitoring results of the observation points in haulage roadway,the law and its mechanisms of surface deformation were analyzed.Research results showed that the haulage roadway was in toppling station,and some bedding deformation had occurred in deep rock mass,with a tendency of toppling to the mined-out areas.Deformation in this area was not obvious and in a steady process.With the expansion of mining in the plane and depth,deep rock mass may occur bending fracture plane and came into toppling-sliding station,with the surface deformation increasing rapidly.The study was of high theoretical and practical value on safe production of haulage roadway in the west of Chengchao iron mine and similar engineering.
