SELF-CONTAINED DEVICE FOR LIFTING MINERAL RESOURCES FROM BOTTOM OF WATER AREA Russian patent published in 2017 - IPC E21C50/00 F42B3/10 

FIELD: mining engineering.

SUBSTANCE: self-contained device for lifting mineral resources from the bottom of the water area includes a grab bucket made of elastic material, flexible links interconnected with the bucket, a bucket closing mechanism, and an actuating sensor for the flexible cavity located in the lifting section. The bucket surface is made with steel spokes evenly spaced throughout the area. The lifting section is equipped with a protective casing with branch pipes for supplying gas to the flexible cavity, fixed in the casing. Inside the protective casing, along its perimeter, there are evenly located cartridges with an explosive substance and a pyrotechnic relay between them, which are, in turn, interconnected through an electric detonator with an actuating sensor of the flexible cavity. In this case, the lifting section is made in the form of a hemisphere, the upper part of which is provided with a porous material, and the branch pipes are provided with check valves.

EFFECT: increasing the efficiency of mineral extraction from the bottom of the water area.
