摘　　要：矿床的地下水位一般随季节变化而变化,但在采区外围进行铀矿勘探时,发现地下水位与季节变化的联动不明显,这与前人对该矿床地下水天然流场的认识存在较大差异。通过收集矿床勘探阶段的水文地质资料,并结合实际测量结果,分析了地浸开采对蒙其古尔矿床地下水系统产生的影响。结果显示,地浸采区上游未受地浸开采影响,采区内部地下水位出现缓慢下降现象,采区下游地下水位呈持续下降趋势。The previous studies of Mengqiguer uranium deposit centred on the directing exploration work and summary of metallogenic regularity.There are few studies on groundwater hydrodynamic field in upstream and downstream of the mining area affected by in-situ leaching.It is found that the linkage between groundwater level and seasonal variation is not obvious in the process of uranium exploration outside the mining area.These changes are quite different from the understanding of the natural flow field of groundwater in the previous exploration process.Previous studies have shown that the groundwater level throughout the deposit varies seasonally.In view of this,this paper analyzes the influence of in-situ leaching mining on the groundwater system of Mengqiguer deposit by collecting the hydrogeological data in the exploration stage and the actual measurement.Through the analysis,it is concluded that the upstream of the in-situ leaching mining area is not affected,the underground water level in the mining area is slowly declining,and the underground water level in the downstream of the mining area continues to decline.This study can provide a new idea for the understanding of groundwater hydrodynamic field in the process of uranium exploration outside the mining area,and also provide data reference for in-situ leaching of uranium.
