矿山发生局部破坏的边界条件主要是由台阶的几何特征所决定，台阶边坡几何特征主要有台阶坡面角、台阶高度、台阶的平台宽度和台阶组合4要素。在对整体边坡角优化的同时，同样需要对台阶的宽度进行优化。通过分析台阶边坡特征，计算出不同规模破坏的边界条件，进而对矿山台阶的宽度进行优化。通过对一个矿山边坡算例的优化分析，在不改变整体边坡角的前提下，对台阶宽度进行优化，可以避免某些大规模的台阶破坏可能，提高矿山边坡的稳定性。
礦山髮生跼部破壞的邊界條件主要是由檯階的幾何特徵所決定，檯階邊坡幾何特徵主要有檯階坡麵角、檯階高度、檯階的平檯寬度和檯階組閤4要素。在對整體邊坡角優化的同時，同樣需要對檯階的寬度進行優化。通過分析檯階邊坡特徵，計算齣不同規模破壞的邊界條件，進而對礦山檯階的寬度進行優化。通過對一箇礦山邊坡算例的優化分析，在不改變整體邊坡角的前提下，對檯階寬度進行優化，可以避免某些大規模的檯階破壞可能，提高礦山邊坡的穩定性。

The boundary conditions of partial failure are mainly decided by geometrical characteristics of slope .The geomet-rical characteristics are formed by angle ,height ,platform width and combination of bench slope .The platform width should be optimized while optimizing the angle of the whole slope .The optimization of platform width is completed by analyzing the geometrical characteristics of mine slope ,and computing the boundary conditions of different partial failure .Based on a mine slope ,an example of optimization is analyzed .The optimization of platform width is completed under the premise of un-changing the overall angle .The optimization can avoid lots of possibility of damage scale and enhance the stability of mine slopes .
