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。
以蘭尖鐵礦露天轉地下開採為工程揹景，針對尖包包礦區露天採場邊坡穩定性問題，利用簡化Bishop法，對露天採場的邊坡穩定性進行分析。通過數值模擬分析，得齣選取的典型邊坡剖麵的安全繫數，併確定邊坡最危險滑裂麵的位置。研究結果錶明，蘭尖鐵礦尖包包礦區露天採場的邊坡是穩定的。

The paper,taking the transition of Lanjian Iron Mine from open-pit mining to underground as the engi-neering background,uses simplified Bishop method to analyze the slope stability in open-pit stopes.Numerical simula-tion 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.
