摘要
掌握保安矿柱回采过程中的地表变形规律,对保护地表的建筑物和构筑物有重要意义。以程潮铁矿为背景,采用FLAC3D数值模拟分析方法,从地表水平变形、地表沉降、选厂位置地表变形、应力分析和塑性区分析等5个方面对西区保安矿柱回采过程的地表变形进行了分析,得出了地表变形规律,并提出回采建议。
Master surface deformation law of safety pillar in stoping process has an important mean- ing for protection of surface buildings and structure. Taken the Chengchao Iron Mine as an engineering background, surface deformation of western safety pillar in stoping process was analyzed by FLAC3D and from five aspects as surface horizontal deformation, ground settlement, plant location surface deformation, stress analysis and plastic zone analysis, surface deformation law was obtained and stoping suggestions were proposed.
