FIELD: mining industry, possible use for extracting solid mineral resources using well hydro-extraction method and during construction of underground reservoirs in soluble rocks. ^ SUBSTANCE: method includes drilling well 2, installing well implement 4 in it, supplying water from ground body of water 8 through well implement 4 into created underground chamber 14, lifting hydro-mixture of mineral resource and hydro-transport thereof to pool 12 with return of water into ground body of water 8. trench 13 is driven in advance with inclination from well mouth 2 to ground body of water 8, water is supplied to underground chamber 14 via external 5 column of pipes of well implement below level of lower end of central 6 pipes column with lifting of hydro-mixture of mineral resource through this column with productiveness, making it possible to accumulate sedimentation 15 of mineral resource on the bottom of underground chamber up to level, exceeding the level of lower end of central 6 pipe column, while water is drained to the surface along well 2 with return to ground body of water 8 via trench 13. ^ EFFECT: decreased energy costs of lifting of hydro-mixture of mineral resource with simultaneous simplification of its dehydration process. ^ 2 cl, 4 dwg, 1 ex |
