依据矿区补勘钻孔抽水取得的水质化验资料,重点对影响煤层开采的奥陶系中统石灰岩岩溶裂隙含水层和太原组灰岩岩溶裂隙含水层进行了水化学特征分析,结果发现,奥陶系峰峰组含水层中SO42-离子含量普遍较高,大部分地段高于HCO3-离子含量,阳离子以Ca2+和Mg2+离子为主,水化学类型以SO4-Ca· Mg型为主；上马家沟组含水层SO42-离子含量较峰峰组岩溶裂隙水明显下降.根据各钻孔水质化验的主要离子成分、矿化度、总硬度及水化学类型进行各含水层间的水力联系分析,认为峰峰组含水层与上马家沟组含水层、太灰含水层与奥灰含水层水力联系均较弱.该研究可为矿井开采中开展水害防治提供参考.%According as tested water quality data from the mine area complementary exploration pumping tests, put emphasis on middle Ordovician limestone karst fissure aquifer and Taiyuan Formation limestone karst fissure aquifer hydrochemical feature analysis, the result has shown, SO42- ion content is generally high in Ordovician Fengfeng Formation aquifer, in most places higher than HCO3- ion content, while the cations are mainly Ca2+ and Mg2+, hydrochemical type is mainly SO4-Ca·Mg type; SO42- ion content in the Shangmajiagou Formation aquifer is obviously lower than in the Fengfeng Formation karst fissure water. According to the analysis of hydraulic connection between aquifers based on each borehole water main ion composition, degree of mineralization, total hardness and hydrochemical type have considered that hydraulic connections among Fengfeng Formation, Shangmajiagou Formation and Taiyuan Formation limestone fissure aquifers are all rather weak. The study can be a reference in water hazard controlling during coal mining.
