| 摘 要： | 以采用无底柱分段崩落法的武钢程潮铁矿开采为工程背景，采用GPS测量和水准测量，建立了193个水平位移点和95个沉降点的地表塌陷监测系统，对塌陷区中心和周边地带进行为期12个月的地表变形监测，特别是对沉降量、沉降漏斗发展过程剖面图、矿区关键构筑物的变形、地表移动边界随时间及地下采空区的扩展关系分析，总结出该矿地表塌陷的特征和一般规律。

| Abstract: | Based on Chengchao Iron Mine of Wuhan Iron and Steel Company,which uses pillarless sublevel coving mining mothod,as the engineering background,using GPS survey and leveling survey to establishment a surface subsidence monitoring system which has 193 horizontal displacement monitoring points as well as 95 settlement points,monitoring the center of collapse areas and surrounding areas for a period of 12 months,especially to analysis the settlement,developing process of settlement crater profile,deformation of the mine key structures,the extended relational between surface moving boundary with time and underground goaf.The general law and characteristics of surface subsidence are summarized. |
