摘要
依据柳林西部中奥陶统峰峰组的岩性,将其划分为四个层段,根据钻孔岩性、抽水试验、水化学分析及岩样压汞试验成果,得出了峰峰组的弱含水特征及其与富含水的上马家沟组之间相对隔水层的存在结论,提出了煤层开采中峰峰组具有相对隔水层的性质。
According to lithology of Fengfeng Formation, middle Ordovician System divided it into four members. Then based on data from borehole lithologic records, pumping tests, water chemical analyses and rock mereury-injection tests, conclusions were made that the Fengfeng Formation is weakly aquiferous and a relative confining bed exists between the Fengfeng Formation and water-rich upper Majiagou Formation. Put forward a conclusion that during the coal mining, the Fengfeng Formation has a nature of relative confining bed.
