摘要
为丰富露天矿边坡危险度评价方法,针对影响因素中定性与定量指标共存的问题,建立了基于熵权法的模糊混合评价模型。首先将由直觉模糊数、区间数、语言值和区间直觉模糊数组成的混合型评价矩阵统一转化为区间直觉模糊评价矩阵,然后利用集成算子将各个指标因素对应值集成为综合区间直觉模糊数,其中指标因素权重由熵权法确定,最后借助得分值函数进行评价。在神华宝日希勒能源露天矿边坡危险度评价中的应用表明,模型实用性较强且可靠性高。
To further develop the slope risk evaluation method 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 formed by intuitionistic fuzzy value,interval-value,linguistic value,and interval intuitionistic fuzzy value were all 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 factor were determined by entropy theory.At last,evaluation was made according to the score value function.According to the application in risk evaluation of Shenhua Baorixile Open Pit Coal Mine,the model was of strong practicability and high reliability.
