摘　　要：针对济三煤矿七采区水文地质勘探程度不高,抽(放)水试验钻孔数量有限的实际情况,从岩性结构和构造发育特征出发,综合考虑砂岩厚度、砂–泥组合层数、岩心采取率以及砂岩含量等因素,构建岩性结构指数模型,同时,采用断层分维值来定量表述断层构造特征,通过信息复合建立多因素富水性指数综合评价模型,对煤层顶板含水层进行富水性分区,通过有限的实测单位涌水量数据对评价结果进行验证,取得了较好的应用效果。Considering the low degree of hydrologic exploration and the limited number of pumping test in the seventh mining district of Jining No.3 mine,quantitative analysis was carried out on the roof aquifer from two aspects： the lithology structure characteristics and tectonic development features.Firstly,the factors,such as sandstone thickness,the numbers of sandstone and mudstone,core recovery percentage and the percent of sandstone in the strata,were considered synthetically to build the lithology structure index.Secondly,the tectonic characteristics of faults were quantitatively analyzed by fractal dimension.Then,the comprehensive evaluation model of water abundance index was established through information recombination.Zonation of water abundance was made for seam roof aquifer.The evaluation results were verified by actually measured specific capacity and good results have been achieved.
