摘 要: 对古交矿区峰峰组与上马家沟组两含水层之间水位差较小的水文钻孔及其钻孔结构进行分析,发现部分钻孔由于分段止水的问题导致2个含水层发生水力联系,使得水位差较小,给评价奥灰水文地质特征带来困难。同时对以后的工作给出建议:要求止水部位设在峰峰组一段(O2f1),并且止水层段长10~20 m以上。
关 键 词: 水文地质学;奥灰;水文地质特征;隔离止水;带压开采

Abstract: This paper analyzed the structure of the borehole which water level difference is small and found that isolation problem leads to two aquifers occur hydraulic connection, making the water level difference smaller, adds difficulties to the evaluation of the hydrogeological characteristics of Ordovician limestone, then gave suggestions for the future work that sealing parts should be in O2f1, and the length of sealing layers should be more than 10~20 m.
Key words: hydrogeology; Ordovician limestone; hydrogeological characteristics; isolation seal; mining with water pressure
