〔摘 要〕运用数值模拟方法，通过提取计算模型地表节点位移数据、计算地表变形、生成地表位移云图和沉降等值线等做法，对某超大规模深井矿山的地表移动范围进行了圈定。与传统方法相比较，数值模拟充分结合了矿山开采工艺，减少了矿山的征地面积，为深井开采地表移动范围的圈定提供了一定的参考价值。

Abstract  The surface movement range of a super-large scale deep mine was delineated by using numerical simulation methods， such as extracting displacement data of surface in the calculation model， calculating surface deformation， generating surface displacement cloud maps and settlement contour lines， and other methods. Compared with traditional methods， numerical simulation fully integrates mining process， reduces the land acquisition area of the mine， and provides certain reference value for delineating the deep mining surface movement range.

地下矿山开采以后，原岩应力场的平衡被打破，岩体中的应力重新分布，从而引起围岩的变形、位移、开裂、冒落，甚至产生大面积塌陷。（剩余4406字）
