依据哈萨克斯坦某古河道砂岩型S矿床地浸开采的实践经验，结合中国及乌克兰一些古河道型铀矿床的矿化特点及地浸试验中遇到的资源量变化等问题，通过对比分析此类矿床与层间氧化带形矿床的异同，指出古河道型矿床地质-水文地质条件的不均质性和多变性以及矿体零散分布的特点是影响地浸开采的最大因素，提出能否合理组织生产勘探、及时依据条件变化调整和优化开拓方案是能否地浸开采古河道型铀矿床的一个关键，并结合地浸采铀技术工艺的特点讨论了此类矿床生产勘探和开拓工作的内容、方法和基本原则，以期为该类矿床的开发提供借鉴。%On the basis of experience and lessons of in-situ leaching mining of paleochannel-type sandstone-hosted uranium deposits in Kazakhstan ,china and other countries ,through analyzing the main difference between interlayer oxidation-type sandstone-hosted uranium deposit and paleochannel-type sandstone-hosted uranium deposit ,points out the inhomogeneity of geological and hydrogeological condition and mineralization characteristics of paleochannel-type sandstone-hosted uranium deposits are the biggest factors which influences economical feasibility of in-situ leachin mining uranium ,and puts forward rational organization of productive exploration and mine development are only method to solve the problem . Further ,combined with the technological characteristics of in-situ leaching uranium mining ,preliminarily discussed the content ,method and fundamental principle of productive exploration and mine development in order to provide reference for mining this type of deposits by in-situ leaching method .
