摘要以湖北鄂州程潮铁矿西区为例，依据近6 a的地表水平位移、沉降位移变形监测成果，对地下开采引起的地表变形规律进行分析。结果表明：程潮铁矿西区从地表塌陷至今，等值线、移动线和陷落线在矿区东北端扩展最多，并且在2010年1月，设置的关卡门至措施井往西约150 m的矿区公路(以下简称矿区公路)、粉矿堆场及运输隧道东南端处的地表岩体突然加速，究其原因是矿区水平应力得到较大程度的释放，特别是东北端，使得矿区公路和粉矿堆场处深部岩体开始形成弯曲折断面，目前进入沿着高陡倾角的拉张裂缝向采空区的倾倒滑移破坏阶段，地表岩体以快速变形为主，而运输隧道东南端处的深部岩体只是发生弯曲变形，地表岩体在经历较短时间的快速变形之后，又线性稳定增长，进入倾倒破坏阶段。其成果能为其他类似的金属矿山工程提供可借鉴的规律。

Abstract：The measured data of the surface deformation including the horizontal and vertical displacements in the west part of Chengchao iron mine over the period of 6 years were collected and analyzed. The contours，moving line and collapsing line were expanded the most in the northeast area of the iron mine from the initial time of surface subsidence up to now. In January 2010，the displacements of rock mass at a road in mining area，at the surface of the fines yard and at the surface in the southeast of the transportation tunnel were found to accelerate. The reason was that horizontal stress in mines was greatly released，especially in the northeast of the mine. In the mine road and fines yard，bending fracture plane was formed in deep rock mass，and now it entered the stage of toppling-sliding to golf along the high and steep dip angle of tension cracks，with the surface deformation increasing rapidly，while in southeast area of transport tunnel，only certain bedding deformation occurred in deep rock mass. After a shorter but rapid phase of increasing，the deformation became increasing linearly and steadily，and the rock mass there is entering into a stage of toppling failure. The research results may be applied to the similar metal mines for reference.

Key words： mining engineering underground mining horizontal stress surface deformation
