为了更加科学合理的开展矿井防治水工作，需要对威胁煤层开采的含水层进行富水性分区。根据含水层的沉积和构造特征，选取了含水层的砂地比、砂岩厚度、粗砂岩厚度、砂岩层数、断层分维值和褶皱分维值作为富水性的影响指标，采用灰色关联度法确定了含水层富水性与其各影响指标之间的相关性，并利用语气算子比较法确定了各影响指标的权重。在此基础上，运用模糊综合评价模型，对含水层富水性进行了分区。通过与研究区内各工作面实际涌水量对比，发现基于灰色关联度-模糊综合评判法对含水层进行的富水性分区与实际情况较为一致，说明含水层沉积和构造条件是影响含水层富水性的主要因素。

To develop coalmine water controlling scientifically and reasonably, need to carry out water yield property zoning for aquifers threatening coal mining. Based on aquifer sedimentary and structural features, selected aquifer ratio of sandstone to shale, sandstone, grit thicknesses and layers, fault and fold fractal dimensions as influencing indices on water yield property. Using grey correlation analy?sis determined interdependency between aquifer water yield property and influencing indices and using modal operator comparison de?termined weight of each index. On this basis, using fuzzy synthetic assessment model carried out aquifer water yield property zoning. Through comparison with working face measured water inflow in the study area, the water yield property zoning based on grey correla?tion analysis-fuzzy synthetic assessment is rather coincided with actual situation. It follows that the aquifer sedimentary and structural conditions are the main factors impacting aquifer water yield property.
