Abstract: To further rich the evaluation method for the slope risk of open pit coal mine, the fuzzy mixed evaluation model was established based on entropy method according to coexistence problem of qualitative and quantitative indexes in influence factors. At first, the mixed evaluation matrix which was formed by intuitionistic fuzzy value, interval-value, linguistic value, and interval intuitionistic fuzzy value would be unified transferred to interval intuitionistic fuzzy evaluation matrix. Aggregation operator was used to integrate interval intuitionistic fuzzy value of different index factors to comprehensive interval intuitionistic fuzzy value. The weights of each factors were determined by entropy theory. At last, evaluation was made according to the score value function.Through application in the risk evaluation of Shenhua Baorixile open pit coal mine, it reveals that the model has strong practicability and high reliability.
