摘　　要：在分析钻孔岩芯及水文观测孔资料基础上,从奥灰岩溶发育形态、富水性、水位动态变化三方面对新驿井田奥灰含水层进行系统研究,结果表明奥灰岩溶主要发育在奥灰顶部200 m岩层内,以溶孔和溶蚀裂隙为主,局部见孔洞,富水性情况区域差异性大,分布不均。奥灰岩溶水主要接受降水及第四系裂隙水补给,北东南西方向补给强,西北方向补给弱,岩溶水地下径流强,是下组煤开采过程中主要含水层。Based on the analysis of borehole core and the data of hydrogeological observation well,the Ordovician limestone aquifer in Xinyi mine field was studied systematically from Ordovician limestone karst development form,water yield property and dynamic change of water level.The results showed that the Ordovician limestone karst mainly developed in the stratum200 m over the Ordovician limestone,which took solution pores and resorption fissure as main features,holes existed locally,regional differentiation of water yield property was large and the distribution was uneven.Ordovician limestone karst mainly accepted the replenishment of rainfall and the Quaternary fissure water,and the replenishment of NE-SW direction was strong while the northwest direction was weak,the karst groundwater runoff was strong,and it was the main aquifer in the mining process of down-group seam.
