Load Shedding Scheme Optimization Design of the Dump Slope

In this paper, xingshan iron mine as an engineering example. Based on slip field theory, numerical simulation method and limit equilibrium method for the mine slope stability research and evaluation. Meanwhile, a variety of load shedding scheme was designed and optimized design. The results showed that the final dump slope angle is 19.2, considering the most unfavorable conditions in saturated with earthquake. And ultimate load shedding scheme can guarantee the slope stability, and saves the load shedding costs is about 20 million yuan. The economic effect is remarkable.
