摘要
楚—萨雷苏盆地位于中亚哈萨克斯坦东南部,是全球最著名的产铀盆地之一。本文从区域地层和大地构造背景出发,分析了该盆地铀成矿条件和铀矿化时空分布特征,总结了典型矿床的品位、厚度、埋深、形态、矿物成分、化学成分及渗透性、富水性等地质—水文地质方面的特点,结合该地区普遍采用的地浸采铀工艺,探讨了其地浸开采规模化、标准化和低成本的原因,并借鉴哈萨克斯坦在砂岩型铀矿勘查、采冶过程中的先进理念和实践经验,为我国盆地铀资源的研究和开发提出了建议。
Chu—Careisu basin is located in the southeastern part of Kazakhstan, a central Asian nation, and it is one of most uranium rich basins in the world. This article focused on its regional strata and tectonic background, analyzed the metallogenic condition and spatial and temporal distribution features, summarized on the geological—hydrogeological characteristics, including grade, thickness, depth, shape, mineral contents, chemical contents, permeability and water yield property of aquifer, discussed the reasons for its large scale, standardized and low-cost in-situ leaching mining activity based on the mining technology massively-deployed in this region, summarized several advanced ideas and practical experiences of uranium exploration and mining process of sandstone hosted uranium deposits in Kazakhstan, and proposed several suggestions for research and development of uranium resources in China＇s basin terrains.
