摘要
在利用综合测井资料,分析十红滩铀矿床含矿含水层的隔层、夹层物性特征的基础上,阐述了隔层、夹层的成因及其空间展布,并对其厚度进行了确定,讨论了隔层、夹层与砂岩型铀矿的关系以及对铀资源/储量估算和地浸工艺的影响。认为隔、夹层对层间氧化带砂岩型铀矿的形成和地浸开采有重要影响,同时其厚度的确定对于铀矿体的圈定和铀资源/储量的估算,具有重要的现实意义。
The geophysical paramerters of ore-hosting aquifer was summarized with the comprehensive logging data at Shihongtan uranium deposit. The contributing factors to the parameters was analysed to i- dentify the distribution and thickness of the aquifuge and interbed. The relation of these layers to sand- stone type uranium deposit, their impact to resources/reserves estimation and in-situ leach mining tech- nology are discussed. It was suggested that the aquifuge and interbed bring about significant effect to the formation of interlayer oxidation zone sandstone-type uranium deposit, as well as to in-situ leach mining of the deposit and the established thickness play an important role in resources/reserves estimation.
