Improving the efficiency of downhole uranium production by selecting special decolmating solutions and selecting rational parameters of the technology of influencing the near-filter zone of the formation of geotechnical wells, improving the filtration characteristics of the formation depending on the mineralogical composition and structure of sedimentary materials. The structure and composition of sedimentation causing a decrease in the filtration characteristics of the productive horizon of the Syrdarya and Chu-Sarysui deposits are determined. The effective composition of a special decolmating solution for destruction and prevention of sedimentation in the productive horizon with the use of ammonium bifluoride with the addition of sulfuric acid and surfactants was selected. Rational parameters of an innovative technology for improving the filtration characteristics of a productive horizon with the use of special decolmating solutions have been developed and experimentally confirmed. The effectiveness of the developed complex method for improving the filtration characteristics of reservoirs in uranium deposits worked out by the well method is substantiated. The use of an innovative technology to improve the filtration characteristics of ores in difficult mining and geological conditions can increase the uptime and utilization rate of geotechnical wells, which in turn will positively affect the intensity of mining of technological blocks and increase productivity and labor safety, as well as reduce the operating costs of mining enterprises.
