摘　　要：以兰尖铁矿露天转地下开采为工程背景,针对尖包包矿区露天采场边坡稳定性问题,利用简化Bishop法,对露天采场的边坡稳定性进行分析。通过数值模拟分析,得出选取的典型边坡剖面的安全系数,并确定边坡最危险滑裂面的位置。研究结果表明,兰尖铁矿尖包包矿区露天采场的边坡是稳定的。The paper,taking the transition of Lanjian Iron Mine from open-pit mining to underground as the engineering background,uses simplified Bishop method to analyze the slope stability in open-pit stopes. Numerical simulation analysis obtains the safety coefficient of the section of the selected typical slope and identifies the most dangerous location of slipping crack in slopes. The research results indicate that the slope in Lanjian Iron Mine is stable.
