FIELD: mining, in particular, well hydraulic giants designed for hydraulic borehole mining of mineral deposits presented by ore bodies of sheet-, lens-like and similar shapes with different angles of dip. SUBSTANCE: hydraulic giant includes standpipe with barrel, rigid tie-rod and plumb with axle, headframe, platform hinged with plumb axle to which ball joint is secured, guide movably attached to platform. Headframe is made in the form of two sleeves interconnected to each other with their opened sides for rotation round each other. Located in one of sleeves is platform with guide and window for barrel resting on guide. Nozzle is installed on barrel. EFFECT: higher efficiency of mining of mineral deposits due to provision of working of slightly sloping and sloping ore bodies , and increased sizes of worked chambers. 5 cl, 4 dwgu
