FIELD: mining. SUBSTANCE: method for elimination of inrush of clay mass into mine active workings includes introduction into rushed clay mass of freezing columns from additionally driven working or well to form ice-rock plug. Simultaneously, erected in flooded working near boundary of broken through mass is bulkhead, and introduced into clay mass are perforated injectors through which, at first, aqueous solution of surfactant is supplied, and then it is foamed by bubbling gaseous nitrogen and frozen with liquid nitrogen into porous conglomerate. The latter is extracted by tunneling machines. EFFECT: higher efficiency. 2 cl, 1 dwg
