Zusammenfassung:	METHOD OF BOREHOLE HYDRAULICKING OF SOLUBLE MINERALS The invention relates to methods of working metalliferous deposits. The method consists of tapping a pay zone by development boreholes, hydraulically mining the mineral in the pay zone so as to form brine the level whereof is located below the zone of hydraulic mining of the mineral, shaping a working chamber by shifting the zone of hydraulic mining along the axis of the borehole within the confines of the pay zone and lifting the brine to the surface. The hydraulic mining of mineral is alternated with the lift-of brine to the surface, whereby the zone of hydraulic mining is shifted from the floor of the pay zone to the roof thereof at a speed which is not less than the speed whereat the level of brine is rising in the working chamber.
