Simulation for the Motion of Polymetallic Nodules in Hydraulic Hoist for Deep Sea Mining
نویسندگان
چکیده
The two-phase flow composed of polymetallic nodules and the fluid in hydraulic hoist for deep sea mining was simulated by the discrete particle method (DPM). The motion of nodule particles was simulated by the particle-motion-resolved model, in which the effects of Saffman lift force and Magnus lift force were included. The collisions between particles as well as between particles and the pipe wall were also simulated. The simulated results show some motion characteristics of nodules in hydraulic hoist. These results agree with the experimental results in general.

Biological responses to disturbance from simulated deep-sea polymetallic nodule mining
Commercial-scale mining for polymetallic nodules could have a major impact on the deep-sea environment, but the effects of these mining activities on deep-sea ecosystems are very poorly known. The first commercial test mining for polymetallic nodules was carried out in 1970. Since then a number of small-scale commercial test mining or scientific disturbance studies have been carried out. Here w...
متن کاملFrom the Surface to the Deep-Sea: Bacterial Distributions across Polymetallic Nodule Fields in the Clarion-Clipperton Zone of the Pacific Ocean
Marine bacteria regulate fluxes of matter and energy essential for pelagic and benthic organisms and may also be involved in the formation and maintenance of commercially valuable abyssal polymetallic nodules. Future mining of these nodule fields is predicted to have substantial effects on biodiversity and physicochemical conditions in mined areas. Yet, the identity and distributions of bacteri...

متن کاملResilience of benthic deep-sea fauna to mining activities.
With increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyz...
متن کاملDeep-sea Mining: An Emerging Marine Industry
Deep-sea mining is an emerging marine industry that presents particularly complex challenges due to its multi-faceted technological, scientific, environmental, social, industrial, political, economic and legal aspects, all of which must be addressed to achieve commercially viable results. These aspects are governed by the burgeoning regulatory regime promulgated by the International Seabed Auth...
