摘 要:为了分析不同含水层系统中水流场分布,利用淮北任楼井田及所在的临涣矿区地表水体、地面长期观测孔、井下出水点从上而下分别采集了地表、第四系第四含水层、二叠系煤系砂岩裂隙含水层、石炭系太原组岩溶含水层及奥陶系岩溶含水层30个水样,测试了δD,δ18O与咸化指标总溶解固体TDS.结果表明:临涣矿区四含和太灰地下水表现18O漂移,煤系地下水表现D漂移,奥灰地下水漂移特征不明显;临涣矿区四含与太灰地下水δ18O与TDS呈负相关关系,煤系地下水δD与TDS呈正相关关系。任楼井田煤炭的开采对四含与煤系水的影响较大,四含水由井田西北与东南方向向采区径流,煤系水由井田四周向采区径流;煤炭开采对太灰水影响不大,太灰水在井田范围内由东向西径流.In order to analyze the current field of deep groundwater in different aquifer systems, thirty specimens including the fourth aquifer of the Quarternary, the coal and sandstone cranny aquifer, the Taiyuan limestone aquifer and the Ordovician limestone aquifer were obtained from the top down by surface water, the long-term observation bores and mine streaming water in Renlou colliery, the local Linhuan coal district of Huaibei. The δD, δ^180 and the content of tall dissolve solid(TDS for short) in groundwater were tested. The results show that the groundwater in the fourth aquifer and the Taiyuan limestone aquifer takes on 18O excursion in Linhuan coal district, and in the coal aquifer takes on D excursion, but the excursion characteristic in the Ordovician limestone aquifer is not evident. The relation between δ18O and TDS of ground- water is negative correlation in the fourth aquifer and the Taiyuan limestone aquifer in Linhuan coal district. The relation between δD and TDS is positive correlation in the coal aquifer. Be- cause of the mining in Renlou colliery, the groundwater in the fourth aquifer flows from northwest and southeast to mining areas, and that in the coal aquifer flows from around to mining areas. However, the mining doesn't influence the Taiyuan limestone aquifer evidently so that the groundwater flows from east to west.
