Abstract

This invention belongs to the field of deep-sea mineral resource mining technology and discloses a method for optimizing parameters for vertical lifting of deep-sea granular ore. Under a set conveying capacity, the method optimizes parameters based on the liquid flow velocity V and the critical flow velocity u of the granules. l Satisfying V>u l Under the constraint of +1.5, the pipe inner diameter, particle volume concentration, and liquid flow velocity corresponding to the minimum unit frictional resistance are accurately determined. This invention can effectively improve the efficiency of vertical lifting of deep-sea particle ore, reduce transportation energy consumption, and provide technical support for the efficient mining of deep-sea mineral resources.
