摘要
为了查明陕北某矿的顶板含水层富水性分布规律,在综合考虑该矿地质、水文地质条件的基础上,结合矿井勘探和生产实际,选取了脆塑性岩厚度比、含水层厚度、渗透系数、岩芯采取率和单位涌水量5个因素作为影响含水层富水性的主控指标。并在传统层次分析法(AHP)确定各主控因素权重的基础上,引入改进的模糊层次分析法(IFAHP),建立起含水层富水性评价模型,按照5个等级划分出不同富水性区域,总结富水性的分布规律。
In order to identify the water-richness and zoning rules of the coal roof aquifer in a coal mine of Northern Shaanxi,five influence factors are selected based on comprehensive analysis of the mine hydrogeology data and combination of mine exploration and production practice. IFAHP is introduced to determine the weight of each factor based on AHP. The study area can be divided into five parts, and the zoning rules of rich water is summarized.
