广西大新铅锌矿地下采空区对地面沉陷的影响

Influences of the lead-zinc mine underground goaf in Guangxi Daxin on ground subsidence

针对矿体采空后对地表的影响,对采空区稳定性及地表沉陷进行了分析,结果表明,采取合理方法对浅部未充填采空区进行密实充填,实施地表水管理控制进入地下是控制地表沉降、防止地面建筑物变形和破坏的最有效措施。

Aiming at the influences of ore body which has been stoped out, the author analyses the stability of the goal and the ground subsidence, results indicated that, adopting a reasonable method to densely pack the shallow unfilled goaf and controlling ground water into underground is the most effective measure for controlling the ground subsidence and preventing ground building from distortion and destroying.
