Summary:FIELD: transport and storage devices, particularly for building underground reservoirs. ^ SUBSTANCE: method involves placing adjusting pipe string bottom of directionally drilled well in horizontal position at well outlet; arranging preparation underground excavation for design tunnel reservoir height at initial stage of rock solution between casing and adjusting pipe strings of directionally drilled well; ejecting non-solvent in casing pipe strings along with maintaining non-solvent-brine interface in upper part of preparation excavation or in the case of stepped rock solving at level of each underground tunnel reservoir stage forming; maintaining non-solvent-brine interface in vertical well at level or above level of non-solvent-brine interface of preparation excavation. ^ EFFECT: increased efficiency of underground tunnel building. ^ 6 dwg
