Zusammenfassung:FIELD: rock mining, particularly to develop gravel-sand deposits. ^ SUBSTANCE: rid comprises body made as U-shaped pontoon and having docking mechanism, which provides connection of similar pontoon sections to maintain floatability thereof in the case of suction head weight increasing. The rig also has suction head made as downhole hydraulic mining tool and having ground receiving means and portal crane for ground receiver lifting and lowering arranged in front pontoon part. The ground receiver is lifted and lowered by suction head rotation about axle arranged in central pontoon part. The rig also has sludge line connected to suction head. ^ EFFECT: possibility of mining work performing at variable development depth. ^ 4 dwg
