摘　　要：在邹城市宏河矿业集团横河煤矿井田范围内,有多眼供水井。由于这些供水井大部分穿透了第四系松散层,致使上部含水层和底部含水层串通,造成对矿井水的补给。但较长时期以来,由于缺乏直接的证据,对供水井与煤矿底含涌水之间的关系看法不一,从而造成对矿井水防治决策的困扰。通过化学示踪法跟踪地下水的流向,证实是供水井自身结构串通了第四系含水层上、中、下组,从而造成上组含水层对底部含水层的补给。Connection test is a valid method in confirming the flow path of ground water. In Henghe coal mine region, there are several supplying wells which collude the upper aquifer and the bottom aquifer, resulting in water supplying to the drain bores as most of these wells drilled through the stratum of quaternary. But over a long term, opinions about the relationship between these supplying wells and the water welling in bottom aquifer are variable for lacking of directly evidence, which also leads to difficulties in decision-making. This paper results from the connection test to verify that it's the wells' self-structure that forms the channels among different aquifers of quaternary through tracing the ground water flowing direction with chemistry tracer.
