ABSTRACT
This article discusses the methodology for increasing the uranium extraction, in the process of development of hydrogen type uranium deposits of the Republic of Kazakhstan. The analysis of the effectiveness of the standard repair work and methods was applied. The plasma-impulse technology (PIT) using is proposed to increase the permeability of the ore-layer decolmatate the well filters and as a result, intensify the leaching process. The article reviews the physical impact of PIT on the reservoir. Due to the resonant effects in the reservoir as a result of the elastic impact, the process of uranium transition to the mobile form is intensified. A schematic model of the elastic resonance action on a uranium-containing ore-layer using PIT is presented. Positive results were obtained on the application of the proposed technology on some uranium ore deposits of the Republic of Kazakhstan at all stages of their development – while the opening of a deposit, blocks acidification and leaching. Based on the results of testing the technology, a combination of PIT with standard methods of repair and restoration work was developed. The application of the author’s methodology intensifies the process of uranium transition to the mobile form due to resonance at dominant frequencies and stabilizes the metal yield. High flow rates of pumping wells with an increased or stable metal yield will increase uranium production, its extraction rate and, accordingly, shorten the life of the deposit.
