The study develops a mobile unit for the chemical treatment and flushing of technological wells in the uranium industry, aimed at improving repair and restoration work efficiency in challenging mining and geological conditions. The research included the design and testing of the unit at the Karamurun field (Kazakhstan) with 60 geotechnological wells. The mobile unit featured specialised components like pumping equipment, pipelines for reagents, and was upgraded to handle difficult conditions, enhancing operational reliability and safety. The tests revealed that the unit reduced well downtime by 50% and increased productivity. The cost-effectiveness of the unit was KZT 14,068,374 (USD ~28,400) annually, with a payback period of 4.4 years. The results demonstrated the unit’s significant impact on improving filtration characteristics in hard-to-permeate rocks and its potential for improving production in the uranium industry. This solution offers new prospects for developing geological deposits and enhancing industry efficiency.
