FIELD: mining.
SUBSTANCE: invention relates to mining and can be used for dredging soil. The system to extract submerged sediments (3) of the geological allotment and their allotment is considered. From the free floating mining ship (1) the mixture of water and sediment is sucked by the submerged pump assembly through the flexible hose (7) made with the ability of winding on a rotating spool (5) located on the said mining ship when the ship sails over the geological allotment. The sucked mixture is then immediately fed into one of the series of free-floating cargo and transporting assemblies (27), which float along the board side. The system is provided with the length regulators of the suction hose and the length of the hanging ropes.
