For the example of the mine in both sides of the Wulagai reservoir,the side slope stability is analyzed by using the polar stereographic projection and the mechanics calculations qualitatively and quantitatively,and through application of the ROCKFALL tool,the motion state of side slope deformation instability is simulated numerically,the graphics of jumping height and total energy distribution of dangerous rocks are drawn,and it lays the foundation of the mine side slope restoration.%以乌拉盖水库两岸矿山为例,运用极射赤平投影方法和力学计算法对边坡稳定性进行了定性和定量分析,并且应用ROCKFALL工具对边坡失稳变形后的运动状态进行了数值模拟,绘制出危岩体弹跳高度图和总能量分布图,为生产矿山的边坡治理恢复提供了依据。
