Title: | STUDY OF COLLECTION PROCESS FOR HARVESTING OF SEABED MINERALS FOR DEEP SEA MINING | Authors: | WANG WENTAO | Keywords: | mining, experimental, prototypes, force, collection, sedimentary disturbance | Issue Date: | 20-Jun-2018 | Citation: | WANG WENTAO (2018-06-20). STUDY OF COLLECTION PROCESS FOR HARVESTING OF SEABED MINERALS FOR DEEP SEA MINING. ScholarBank@NUS Repository. | Abstract: | This project aims at the experimental study of collection process for harvesting minerals in a lab scaled tank. Complexity, process limitations and sedimentary disturbance are found for previous experimental tests. This project is to better understand the interaction between the physical nodules harvesting system and the seabed to minimize the disturbance and resulting environmental impact to the seabed. Test scaled prototypes representative of the harvesting equipment are designed and constructed to validate the numerical models predicting sedimentary disturbance. Meanwhile, a setup to measure the forces acted by the sediment on the moving prototypes is designed to better understand the motion of the collector. The graphs plotting the force loaded on the plate shows the trend obtained with the simulation matches the experimental one very well. It was found that collector with transverse rods appears to generate a downward suction flow through the network of rods which could reduce the plume generated which may lead to reducing the environmental impact on sea bed. | URI: | https://scholarbank.nus.edu.sg/handle/10635/147848 |
