摘　　要：为改善地下水示踪连通试验中示踪剂投放量大、迁移缓慢、试验周期长和效果不确定等问题,提出了以碘化钾为示踪剂的放水和示踪联合试验方法。为检验这种方法的效果,先后在鹤壁矿区寺湾矿进行了多点投放-单点接收的放水和示踪联合试验、在灵宝市银家沟硫铁矿进行了单点投放-多点接收的放水和示踪联合试验、在汝州矿区的朝川矿进行了单点投放-单点接收的放水和示踪联合试验。试验不仅查明了这些富水矿井地下水补给来源、径流通道和断层导水性,还证实了放水和示踪联合试验较天然地下水径流条件下示踪试验,更能促进示踪剂在裂隙岩溶含水层中的迁移,缩短了试验周期,并可确保试验达到预期效果。The application of traditional tracing connection test needs a lot of tracer in general and has some defects that are the movement speed of a tracer is slow,test period is long and the effect is uncertainty. In or- der to improve these defects, a test combined with a dewatering test and a tracing test was applied to mine un- derground areas. This dewatering and tracing combined test took KI as a tracer. The multiple drop point-singe receipt point tracing test was implemented in Siwan mine in Hebi mine areas. The singe drop point-multiple receipt point tracing test was implemented in Yinjiagou pyrite mine in Lingbao city. The single drop point-sin- gle receipt point tracing test was implemented in Chaochuan mine in Ruzhou mine area. These tests confirmed the recharge resource and run-off channel of groundwater, and judged the conductivity of faults. They also proved that the dewatering and tracing combined test can accelerate the movement of trace and shorten the test period. Thus, the efficiency of the test can be ensured.
