There are several factors influencing the slope stability of open pit mine, and the common methods can be divided into the subjective weighting method and the objective weighting method. In this paper, we make comprehensive evaluation of slope stability by using AHP method and entropy weight method. First of all, we make evaluation of the first level indicators, using AHP method to determine the weight of factors and then use the entropy weight method to calculate the influence factors, the conclusion has certain reliability and scientific nature. Through field monitoring, we get the membership function of each influence index by using assignment method and trapezoid distribution. Following the principle of maximum membership, slope II is the most stable, followed by slope V and slope I, slope III and slope IV are poor stability. This result is consistent with the on-site inspection, and then we proposed treatment measures according to the engineering practice.
