摘要
基于模糊数学原理对采空区稳定性进行综合评判,在评判过程中按各因素的类型建立评估因素集,建立2级模糊评判模型;采用四值逻辑分区法确定隶属函数,进而求解定量因素;通过专家打分法量级划分确定定性因素,进而确定判断矩阵;采用层次分析法分析影响采空区稳定性的动态、静态、定量、定性指标等因素,建立评估因素权重集.然后将判断矩阵与因素权重集进行交、并、补运算.以老鸦巢矿区608采空区为例,得出评判结果为(0.099 7,0.496 2,0.079 2,0.325 0),按最大隶属原则确定该采空区为危险度较高.
Based on fuzzy mathematics, this paper evaluates the stability of mined - out areas comprehensively, establishes concourses of evaluation, and builds a two - level fuzzy evaluation model according to different cate- gories of evaluative factors. The four -valued logic classification is used to determine the subordinate functions in order to get the quantitative factor. Meanwhile the expert scoring is applied to qualitative factor. The evaluating matrix is then obtained based on the two factors. With the adoption of analytic hierarchy process, the dynamic, static, quantitative and qualitative indexes influencing the stability of mined -out areas are analyzed in order to establish weight concourses of evaluation factors. The concourses are then calculated together with the evaluating matrix in aspects of intersection, union and complementary set. Finally, the 608 mined - out area of Laoyachao ore-field is taken as an example, and the results of evaluation are （0. 0997,0. 4962,0. 0792,0. 3250）. According to the maximum subordinate principle, this minedout area is in real danger.
