摘　　要：结合鸡笼山金矿的具体工程实际,运用FLAC3D有限差分数值模拟软件对试验采场进行了稳定性分析,得出了控顶高度为6 m时采场围岩的应力、位移分布特征。从而在保证矿山安全生产的前提下,为最大限度地提高采场生产能力及矿石回采率提供可靠依据。Combining with the engineering practice of Jilongshan gold mine,this paper analyzed the stability of stope by adopting the FLAC3D finite difference numerical simulation software and obtained the distribution of the stress and displacement field of surrounding rock mass when the stope height was 6 m.The results provided a reliable basis to increase the stope production capacity and improve the recovery rate of ore maximally.
