The technology of downhole uranium production used at mining enterprises in Kazakhstan is described, the factors affecting the decrease in the filtration characteristics of productive formations are studied in detail, and an effective method is described for increasing the downhole uranium production. The applied methods of intensification of downhole production at uranium mining enterprises are considered, the positive and negative aspects of the electroplasma and chemical methods are discussed. Calculations of the working values of the hydro-wave method of destruction of clogging formations in the well and the parameters of the solution supply during repair and restoration work are presented. Based on the calculation of the operating parameters, a diagram of the dependence of the operating cycle of the hydropercussion machine on the flow rate of the water supplied to the machine is constructed. The developed 3D model of the hydropercussion apparatus for increasing the permeability of the productive horizon is presented. The advantages of the use of the hydrodynamic method for restoring the permeability of the productive horizon in the conditions of downhole uranium production in difficult mining and geological conditions are disclosed. The optimal parameters for intensification of downhole uranium production in difficult mining and geological conditions are recommended, and a method for using a hydropercussion apparatus in combination with traditional methods of well regeneration is developed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
