Pump-lockage ore transportation system for deep sea flexible mining system
Based on characteristics of deep sea flexible mining system, a new pump-lockage ore transportation system was designed. According to Bernoulli equation and two-phase hydrodynamics theory, parameters of the new system were obtained and four ore transportation systems were analyzed. The results indicate that the pump head of 1 000 m mining system is 100–150 m and that of 5 000 m mining system is 660–750 m. In addition, based on similarity theory, a model of the new transportation system was made, which can simulate more than 5 000 m actual ore transportation system. So both theory and experiment prove that the new pump-lockage ore transportation system is an ideal design for deep sea flexible mining system.
