Selecting the rational parameters for restoring filtration characteristics of ores during borehole mining of uranium depositst

Purpose. The research purpose is to increase the efficiency of borehole uranium mining by selecting special decolmating solutions and rational parameters technology for influencing seam near-filter zone geotechnological boreholes, as well improving filtration characteristics seam, depending on mineralogical composition ores structure sediment-forming materials. Methods. method X-ray phase analysis was used study powders. core material samples were studied transparent sections using a LEICA DM 2500 P microscope. content elemental host rocks in productive horizon controlled an atomic emission spectrometer. Findings. Based results, quantitative-qualitative horizon, sedimentary formations from technological boreholes have been determined, revealing various levels horizon. It has found that Campanian complex multicomponent formations, representing mixture sediments mechanical-chemical origin. Originality. results quantitative-qualitative, microscopic, thermal methods ore-bearing horizons at Syr Darya depression deposit comparatively analyzed. Santonian, Maastrichtian, Northern Kharasan field, depression, also sampled studied. choice most appropriate chemical reagents dissolution prevention formation porous media substan-tiated microscopic method. Practical implications. A detailed comparative makes it possible more accurately plan blocks, minimizing emerging risks. Using developed combined intensifying mining, reduce its operating costs. At same time, ecological industrial safety work intensi-fying leaching increases.
