改进层次分析法在矿井水文地质类型划分中的应用

矿井水文地质类型划分是矿井水文地质工作的一项重要内容，对分析充水条件，评价水害威胁程度，指导矿井防治水工作具有重要意义。引进最优传递矩阵对层次分析法进行改进，将改进的层次分析法应用到水文地质类型划分中。以内蒙古呼吉尔特矿区4对生产矿井为例，在分析水文地质条件的基础上，建立了矿井水文地质类型划分的评价指标体系，利用改进的层次分析法，计算各项影响因素的权重值，建立数学模型计算每个矿井综合得分Z值，根据计算结果，呼吉尔特4对生产矿井水文地质条件均为复杂型。 

Application of improved hierarchic analytic process in the classification of mine hydrogeological types

The classification of mine hydrogeological type is an important part of mine hydrogeology work. It is of great significance to analyze water filling conditions, evaluate water hazard and guide mine water prevention work. In order to evaluate mine hydrogeological conditions, this paper introduced optimal transfer matrix to improve hierarchic analytic process, and then applied this method to classify mine hydrogeological types. Taking four pairs of active mines in Hujierte mining area of Inner Mongolia as an example, the evaluation index system for classification of mine hydrogeological types was built on the basis of analysis of the hydrogeological conditions, then theoretical weight of different influencing factors was calculated using improved hierarchy analysis process. The mathematical model was set up to calculate Z value of the composite score of each mine. According to the calculation result, the hydrogeological conditions in four pairs of active mines are all of complex type.
