摘要
在系统收集济三煤矿十二采区已有的勘探资料和揭露的地质及水文地质资料的基础上,对采区3煤层顶板砂岩含水层水文地质特征进行了分析。利用多因素复合分析法,综合考虑3下煤层顶板砂岩厚度、砂泥岩组合及砂岩含量、构造复杂程度等因素,对3下煤层顶板砂岩含水层富水性进行了分级分区,为采区3煤顶板砂岩水防治提供了依据。
Based on the existing exploiting data and geological and hydrogeological information in 12th mining section of Jining third mine,the paper analyzed the hydrogeological characteristics of the sandstone aquifer on the roof of 3 coal seam.The water abundance of the sandstone aquifer on the roof of 3下 coal seam is divided and classified using the multiple factors analysis method.The conclusion can provides basis for the prevention and cure of the sandstone water on the roof of 3 coal seam.
