本文总结了近三十年来所取得的各类铀矿床的水文地质勘探资料和部分矿床开采验证的结果。根据铀矿床围岩特征和含水条件,归纳出坚硬裂隙岩层、半坚硬孔隙岩层、岩溶和赋存温热水岩层四种含水特点。总结出了引起矿床充水的三个主要因素,即矿体与当地侵蚀基准面的相对位置、地表水体(主要是河流)的影响程度和地质构造发育程度及形态特征。在此基础上,将矿床水文地员条件共分为十六种不同情况,得出一个比较简单、直观的分类表,进一步划分出水文地质条件简单、中等、复杂和极复杂四种类型,并作了简要阐述,列举了典型矿床实例。最后得出铀矿床水文地质条件多数不复杂,而复杂和极复杂类型仅占矿床总数的20％,河水、岩溶和温热水是造成矿床水文地质条件复杂的三个主要因素等结论。
This paper summarizes the hydrogeological exploration data of all kinds of uranium deposits obtained in the recent three decades and the results of some ore deposits verification. According to the characteristics of surrounding rock and water content in uranium deposits, four water features of hard rock, semi-hard rock, karst and warm reservoirs are summarized. Summed up the three main factors causing the water flooding in the deposit, that is, the relative position between the ore body and the local erosion datum, the influence degree of the surface water body (mainly the river), the degree of geological tectonic development and the morphological characteristics. On this basis, the conditions of mine hydrologists are divided into 16 different situations, and a relatively simple and intuitive classification table is obtained, which further divides into four types: hydrogeological conditions of simple, moderate, complex and extremely complicated Made a brief description of the typical deposit. Finally, it is concluded that the hydrogeological conditions of uranium deposits are mostly uncomplicated, while the complex and extremely complicated types account for only 20% of the total. The river water, karstification and warm water are the three major factors that cause the complex hydrogeological conditions of the ore deposits.
