The technology of in-situ leaching of metals from the bowels is based on drilling networks of injection and extraction wells, followed by injection of various solvents and pumping out fluids saturated with a valuable component. During these manipulations, solid particles of minerals are leached and become part of the liquid. In this case, the process of seepage of liquid through the rocks is observed. The process under study is called filtration and is one of the main conditions of rocks for the effective extraction of metals from ores, while it is important to control the hydrodynamic parameters of the rock-liquid system. This article describes studies to identify the dependence of the decrease in the water permeability of the rocks of the productive horizon on the dynamics of injection/pumping out of technological solutions in the mines of in-situ leaching of uranium in Uzbekistan.
