As shown in fig. 1-2, the mineral mixing transportation hose system for positioning and shaping the spiral auxiliary line comprises a mineral transportation hose 2, a mooring line 3, a mooring line tensioning system and a fixing device 8 for the mineral transportation hose 2 and the mooring line 3. The fixing device 8 is a guide groove, a guide tube or a fixing ring. The mooring line 3 is secured to the outer surface of the ore transfer hose 2 in a helically wound form by a securing means 8 for ease of offshore installation. The ore carrying hose 2 and the mooring line 3 are relatively movable. When the tension of the mooring line 3 is adjusted by the tensioner 7, the length of the mooring line 3 in the water changes and moves relatively along the outer surface of the ore transfer hose 2, changing the configuration of the ore transfer hose 2 in the water. Along with the change of the tension of the mooring cable 3, the axial rigidity of the mooring cable 3 is changed, and when the rigidity of the mooring cable 3 is increased, the ore transportation hose 2 can be helped to resist the disturbance of sea waves and ocean currents, the dynamic response of the ore transportation hose is reduced, and the shaping effect is achieved.
