The result shows that because unreasonable shape of slope designed by traditional method, uneven physical strength and concentrated stress appeared when it begins to exploit deep ore. Especially the four bands appear straight-line shape, they are like to be developed into slipped slope under the tension stress in the middle of the bands. Which causes unstable factors to slope and adverse effect to production; the rational slope designed by new method conformity to mechanical theories, this shape can averts concentrated stress caused by upper rock gravity, contemporarily, the stress distributes along the oval ring section, so the integrate stress distribution around slope become more even and reasonable and the stability also be improved than the traditional.
采用有限差分软件FLAC-3D对原设计小北露天坑和优化后的小北露天坑进行了模拟分析，在赋予相同的岩体参数下，从数值模拟计算的结果看，原设计露天坑由于边坡形状设计的不合理，在转入深凹开采时，边坡岩体出现受力不均和应力集中现象，尤其是四个边帮呈直线状态，在边帮中部拉应力的作用下，很容易形成滑坡，不利于边坡的稳定，给生产造成不利影响；优化后的露天坑边坡符合力学原理，转移了上部岩体自重产生的集中应力，同时，边坡应力沿椭圆形环向分布，因而边坡所受应力的整体分布趋于均匀、合理，使边坡的稳定性得到提高。
