塔木素铀矿床含矿层地下水储集和渗流类型分析

Occurrence and Seepage Flow Types of the Ore-bearing Seam Groundwater in Tamusu Uranium Deposit

塔木素铀矿床是一个大型砂岩型铀矿床,水文地质试验表明含矿层渗透性好,钻孔涌水量大。地下水储集和渗流类型是确定铀资源开发方案时需要考虑的重要因素。通过对矿床地质勘查资料研究、岩心观察和物性参数测试可知,矿区经历了多期次断裂构造和岩浆活动,含矿层岩石致密坚硬,多数钻孔岩心中发育有裂隙构造,岩石密度大、含水率低、孔隙度小、渗透性差,含矿层地下水应以构造裂隙水为主,少量孔隙水。建议在下一步地质勘查工作中,加强对含矿层构造裂隙发育、地下水储集和渗流特点的研究。

Tamusu uranium shows discharge from drilling deposit is a large-scale sandstone-type uranium deposit. Hydrography experiment is great and permeability of the Ore-bearing seam is excellent. The occurrence and seepage flow types of groundwater is necessarily important factor when the project of uranium resource exploration is determined. According to study of deposit＇ s geologic exploration date, core＇ s observation and test results of physical character＇ s parameter, the results show that there are several fracture tectonic and magmatic activities in the mining area. The Ore-bearing rock is hard, compact, have low water yield property, few porosity and poor permeability. The groundwater mainly consists of fissure-water, and some few pore-water. It is suggested that fur- ther study on geology and hydrography aims at the development of and the characteristics of the occurrence and seepage flow.
