摘　　要：地下开采会产生大量的采空区,大规模的采空区可能会对矿山的设备和作业人员造成危害,所以采空区的稳定性相当重要。通过FLAC数值模拟方法对东升庙铅锌矿900m中段以上的采空区稳定性进行分析,并对9#矿柱回收前后所造成的对采空区稳定性的影响进行分析,分析表明回收9#矿柱不会对采空区稳定性造成太大的影响。在工程实践中,900m中段以上的9#矿柱回收完后,确实未对采空区的稳定性造成大的破坏性影响,说明FLAC对矿山的安全生产起到了一定的技术指导作用。The underground mining will produce large amounts of goaf, even to cause great damage to mining e- quipment and operating personnel. Therefore, the stability of the mine goal is pretty important. By the numerical simulation method using FLAC software, the goaf stability above 900 m level of Dongshengmiao Lead-Zinc Deposit is analyzed, and the effect to the stability of goaf before and after the recovery of 9^# pillar is also analyzed. The a- nalysis result shows that the recovery of 9^# pillar makes little affect on goal stability. In engineering practice, as 9^# pillar ahove 900 m level is recovered, it has not caused great destruction to the stability of goal, which indicates that FLAC numerical simulation can provide technical guidance for safety production of mine.
