摘要
针对卧龙湖煤矿砂岩裂隙含水层水文地质条件复杂的问题,以6~8煤顶底板砂岩含水层(七含)为研究对象,基于岩性结构指数、断裂构造分维值和褶皱变形系数3个定量指标,采用模糊聚类综合评判方法对该含水层富水性进行了综合评判。研究结果表明,卧龙湖煤矿七含以中等富水性为主,弱富水性区域主要分布于矿区北部和中西部,强与极强富水性区域集中分布在矿井南部;基于冲洗液最大消耗量和岩芯采取率等水文地质信息,验证了模糊聚类综合评判结果的可靠性。
In view of the problem that the hydrogeological condition of sandstone fractured aquifer in Wolonghu Coal Mine is complex,taking the sandstone aquifer of coal roof and floor from the 6 th to the 8 th layers（Qihan） as the research object,based on 3 quantitative indexes of lithologic structure index,fractal dimension of fault structure and fold plane deformation coefficient,the water abundance of the aquifer was evaluated by fuzzy cluster comprehensive evaluation. The results showed that Qihan of Wolonghu Coal Mine are mainly medium water abundance area,the weak water abundance area are mainly distributed in the north and the midwest of the mining area,strong and extra-strong water abundance area are concentrated in the south of the mining area. Based on the hydrogeological information such as the maximum consumption of washing liquid and the adoption rate of core,the reliability of the comprehensive evaluation result of fuzzy clustering is verified.
