Experimental Study on Optimum Transport Velocity for Deep-sea Mining Pipeline Transportation

摘要

On the stage of pre commercial exploitation, the safety and economiccost become the main research content in the study of deep-sea miningpipeline transportation technical. The laboratory has been established tostudy on the deep-sea mining pipeline transportation for a long time.Based on the results of these research, the experimental study ofdifferent particle size and concentrations for artificial manganesenodules had been carried out in the test system. The followingconclusions were obtained. 1. Resistance loss in different particle sizeand concentration, 2. The best ratio of particle size and concentration, 3.The Empirical formula of the optimal transport velocity.
