Biz tomondan tadqiqot olib borilganda uranni er ostida tanlab eritib olish texnologiyasida tog‘ jinslarida noturg‘unfiltrlanish harakati kuzatildi, suyuqlik harakati bo‘yicha filtrlanish koeffitsienti laminar va turbulent oqimi bo‘yicha tog‘ jinsiningva eritmaning fizik xossalarini hisobga olish zarur. Tog‘ jinslarining bo‘shliqlarida eritmaning harakati judda qiyin tasniflanadi,shu uchun amaliyotda filtrlanish tezligini hisoblaganda o‘rtacha ifoda bilan hisoblanadi, oqimning harakat tezligi alohida nuqtakesimi bilan belgilanadi.
Tayanch iboralar: uranni tanlab eritish, eritmaning tarqalishi, sulfat kislota, filtralanish, kimyoviy reakssiya, filtrlanishtezligi, uran miqdori,filtrlanish koeffisienti, mahsuldor eritma, ishchi eritma.
The non-stationary mode of filtration of solutions of underground uranium leaching as from weakly permeable ores whendetermining the filtration coefficient under laminar and turbulent regimes, and filtered leach solutions are describes in the article.The motion of the liquid between the grains of the rock is very complex therefore in calculations in practice consider the averagevalue of the filtration rate, which depends on the velocities of elementary flows at individual points of the cross-sectional area.
Key words: uranium leaching, free fluid, sulfuric acid, filtration, chemical reaction, filtration rate, uranium content,coefficient of filtration, product solution, working solution, water bearing stratum, range of duty, injection hole, ore body,useful element, concentrating, dilution, leakage calculation, Aerodynamic and hydrodynamic curtains, aquiclude, deep depth, lithology, draught loss.
