中文摘要：

根据十红滩矿床含矿层的高矿化度地下水特征,应用水文地球化学原理,在分别对酸法地浸造成硫酸钙沉淀和碱法地浸导致碳酸钙沉淀的原因进行系统分析的基础上,通过模拟计算与实验室试验得出了适合该矿床酸法与碱法地浸采铀的水文地球化学条件,对指导高矿化度条件下的砂岩铀矿床地浸开采具有重要现实意义。

英文摘要：

According to the hydrogeochemical features of high mineralized underground water in Shihongtan deposit,the hydrogeochemical principles were applied to analyze the reasons for CaSO4 precipitation by acid in-situ leaching and CaCO3 precipitation by alkaline in-situ leaching.Based on this,the optional hydrogeochemical conditions for both of methods were obtained by the simulation calculation and lab tests.The above study is of importance for in-situ leaching exploration of sandstone type uranium deposits under high mineralized underground water.
