摘　　要：我国金属矿山具有分布范围广,总量大,空间形态多样、规律性差的特点。随着采空区塌陷事故的增多,给周边居民的生命财产安全造成巨大隐患,如何准确客观地评估采空区的稳定性,越来越受到人们的重视。结合某金属矿山采空区,采用"三带理论"、岩石移动带理论和数值模拟方法对沉降范围进行研究,并分析其对地表建筑物产生的影响。China's metal mines have the characteristics of wide distribution range,large total volume,diverse spatial forms and poor regularity.With the increase of collapse accidents in the mined-out area,leading to high potential risks to the lives and properties of the surrounding residents.More and more attention has been payed on how to accurately and objectively evaluate the stability of the mined-out area.In this paper,the"three-zone theory",rock movement zone theory and numerical simulation method are used to study the subsidence range in conjunction with the goaf of a metal mine,and analyze its impact on surface structures.
