高家堡井田主要含水层为白垩系下统华池组和洛河组。在分析矿井水文地质特征的基础上，通过抽水及水力连通试验，查明了矿井主要含水层的富水性及连通性。结果表明：华池组（K1h）与洛河组（K1l）下段富水性弱，洛河组（K1l）上段富水性中等，洛河组（K1l）中段或中上段富水性强；华池组含水层富水性较洛河组含水层弱得多，两含水层不存在明显的水力联系；洛河组（K1l）中上段之间的水力联系较为明显，洛河组（K1l）中上段与下段之间的水力联系较弱；洛河组含水层渗透系数大，水头压力大，厚度大、分布广、富水性较强，为煤层顶板的间接充水含水层，是矿井防治水的主要对象。
高傢堡井田主要含水層為白堊繫下統華池組和洛河組。在分析礦井水文地質特徵的基礎上，通過抽水及水力連通試驗，查明瞭礦井主要含水層的富水性及連通性。結果錶明：華池組（K1h）與洛河組（K1l）下段富水性弱，洛河組（K1l）上段富水性中等，洛河組（K1l）中段或中上段富水性彊；華池組含水層富水性較洛河組含水層弱得多，兩含水層不存在明顯的水力聯繫；洛河組（K1l）中上段之間的水力聯繫較為明顯，洛河組（K1l）中上段與下段之間的水力聯繫較弱；洛河組含水層滲透繫數大，水頭壓力大，厚度大、分佈廣、富水性較彊，為煤層頂闆的間接充水含水層，是礦井防治水的主要對象。

The main aquifers in Gaojiabu minefield have lower Cretaceous Huachi and Luohe formations. On the basis of hydrogeologi?cal features analysis, through pumping test and hydraulic connectivity test have identified water yield property and connectivity of main aquifers in the coalmine. The result has shown that the water yield property of Huachi Formation (K1h) and lower member of Luohe For?mation (K1l) is weak, upper member medium, middle member or middle upper member strong. Water yield property of Huachi Forma?tion aquifer is much weaker than Luohe Formation aquifer, no obvious hydraulic connection between them. Hydraulic connection be?tween Luohe Formation middle and upper member is obvious, middle upper member and lower member is weaker. Luohe Formation aquifer has large permeability coefficient and head pressure, thick and widely distributed with rather strong water yield property, thus the coal roof indirect water filling aquifer and main object in coalmine water controlling.
