摘要: 采空区治理在预防矿山地质灾害中具有非常重要的地位。为了确保符山铁矿尾矿库的安全稳定运行,针对某民采铁矿采空区进行了三维激光探测,对采空区的稳定性及冒落后果进行了分析,提出了综合的治理方案。治理方案实施后,消除了井下民采空区重大安全隐患,保证了尾矿库安全稳定及矿山的正常生产,可为其他矿山采空区治理提供参考。

Abstract: The treatment of mined-out areas plays an important role in prevention of mine geological disasters.In order to ensure safety and stability of tailings dam in Fushan Iron Mine,a three-dimensional laser detection was made for a minied-out area of iron ore to analyze its stability and the cabing risks.Then,a comprehensive management plan was proposed.After the implementation of treatment programs,some significant security risks underground the mined-out area are eliminated,and the security and stability of tailings and the normal production in mine are ensured,thus providing a reference for the treatment of other mined-out area.
