This paper presents the results of experimental research applications "pumping wells" when the mining of uranium deposits by the method of In-Situ Leach Mining ISL in mine "Karatau". Analyzed the experience results of uranium deposits development in the conditions of high-pressure nature of groundwater. The experimental works have been conducted using proposed “pumping wells” technology. The implementation of the proposed "pumping well" technology did not affect the Me and pH values in comparison with the actual technology, but it did reduce the production cost. It is proved that by using the proposed technology and schemes in conditions of high-pressure nature of groundwater reduces the cost of procurement of cables, significantly reducing the cost of acquisition of submersible pumps, savings in the end cap.
