The recovery of the residualore-body under the slope of the open-pit, easily results in the second unloading of the slope.
露天矿边坡驻留矿体开采使边坡产生了第二次卸荷作用。

Through the numerical analysis, the change mechanism of the slope stress in the mining of the residualore-body is investigated and the slope stability is analyzed.
通过数值模拟计算，研究了驻留矿体开采边坡岩体的应力变化机理，分析了边坡稳定性情况。
