Геология и особенности извлечения урана методом подземного скважинного выщелачивания на месторождение Буденовское (Южный Казахстан)

Abstract

Эпигенетические месторождения урана региональных зон пластового окисления представлены большой группой месторождений в пределах Шу-Сарысуйской и Сырдарьинской ураново-рудных провинций. Общие ресурсы, заключенные в месторождениях пластово-инфильтрационного типа, весьма значительны и составляют более 75% всех ресурсов урана Республики Казахстан.

The Chu-Sarysu Basin is located in south-central Kazakhstan. It is as much as 250 km wide and extends for more than 600 km from the foothills of the Tien Shan mountains to the south and southeast, and merges into the flats of the Aral Sea depression to the northwest. The northern and western boundary coincides roughly with the course of the Sarysu River while the Chu river flows across the southern part of the basin. The basin is bounded to the SW by the NW-SE-trending Karatau mountain range, which separates the Chu-Sarysu Basin from the southwesterly located Syr-Darya Basin. These two basins originally formed a single basin before they were separated by periodical uplift s of the Karatau Range. The separation took place after the formation of the U deposits.
