摘要
焦作矿区水文地质条件复杂,矿井水害严重,探明矿区含水层组间的水力联系特征,可为水害防治提供科学依据。根据焦作矿区已有的地质、水文地质资料,从当地构造、矿区的水化学和同位素特征三个角度进行分析,发现矿区内奥陶系含水层与石炭系含水层之间有较强的水力联系,且石炭系含水层的主要补给来源为奥陶系含水层;二叠砂岩含水层除了与石炭系含水层存在微弱的水力联系外,与其他含水层无密切联系;第四系含水层的主要补给来源为地表水;地表水及第四系含水层可通过断裂通道补给下部的奥陶及石炭系含水层。
Jiaozuo Mine Area has complex hydrogeological conditions with serious mine water damage,determination of the hydraulic connection between the aquifer groups can provide the scientific support for water damage control.According to the geological and hydrogeological data,the hydraulic connection characteristics between the aquifer groups were analyzed from the perspectives of construction,mine water chemistry,and environmental isotopic characteristics.The results showed that（1）the Ordovician and Carboniferous aquifers have a strong hydraulic connection and the main recharge source of the Carboniferous aquifer is Ordovician aquifer;（2）the Permian sandstone aquifer has no hydraulic connection with other aquifers except for the Carboniferous aquifer;（3）the main recharge source of the Quaternary aquifer is surface water;and（4）the surface water and Quaternary aquifer can recharge the Ordovician and Carboniferous aquifers through the tectonic fault in the mine area.
