摘　　要：根据某金矿I2矿体的水文及地质特征和采矿方法,运用理论计算得出了矿体防水隔离层厚度,并采用有限元数值模拟计算软件Phase^2分析了开采区域围岩变形和破坏特征。结果表明,理论计算与数值模拟计算结果基本吻合,确定防水隔离矿柱厚度为87.95 m。According to hydrogeological and geological characteristics of I2 gold orebody and mining methods for it,the thickness of the waterproof safety pillar was obtained by theoretical calculation,and numerical simulation with finite element method was conducted by using software Phase^2 to analyze the deformation and failure characteristics of surrounding rock in the mining area.The results showed that the theoretical calculation was almost consistent with the calculation by numerical simulation and the thickness of the waterproof pillar was determined as 87.95 m.
