DESIGN AND IMPLEMENTATION OF A JET PUMP DREDGE

English abstract

Purpose. Experimental confirmation of mathematical models obtained in previ-ous studies, testing and industrial implementation of a jet pump dredger. Methodology. Standard methods of experimentation with experimental and in-dustrial mining of construction sand applied with different settings of the jet suction member. Findings. The method for calculating the rational parameters of hydraulic ripper was introduced in the design of a jet suction member with a hydraulic ripper. The use of a jet working member as the main equipment of a jet pump dredger made it possible to efficiently mining a gravel bed during the development of the East-Bugsky-2 construction sand deposit. The industrial implementation of the jet pump installation using the example of an ejector dredger project showed the practical feasibility, technological and economic efficiency of the use of ejector dredgers in the mining of flooded and underwater sand and gravel deposits with a significant content of coarse gravel. To confirm the reliability of the previously obtained analytical dependencies and determine the operational characteristics of the equipment, field exper-imental studies of the jet suction member were carried out.. An ejector dredger is used in the development of the East-Bugsky-2 sand deposit. Conclusion. The use of a jet dredging member as the main equipment of a jet pump dredger made it possible to efficiently mining a gravel bed during the devel-opment of the East-Bugsky-2 field of construction sands.
