FIELD: mining.
SUBSTANCE: device for underwater development of mineral deposits involves transporting reservoir which is hinged to rope by means of rod, gas generator, flexible gas cavity with limit pressure valve, and rope with ballast and float. Transporting reservoir is made in the form of bucket grab with flexible links and connected through gas generator equipped with startup sensor and load-carrying rope to flexible cavity.
EFFECT: excavation of mineral deposits from water area bottom and their lifting to surface irrespective of visibility conditions, with minimum power consumption for loading.
