- Abstract
Deep-sea mining represents an opportunity for an alternative supply of high-tech raw materials. A concept for the extraction of polymetallic nodules from the seabed envisages the use of a harvester that extracts the nodules using a hydraulic principle. To design an effective and efficient mining process, the composition of the material flows must be continuously monitored. A promising technology for this task is the Acoustic Emission (AE) technology, which has already been successfully used for material flow characterisation of aggregates transported by belt conveyors. In the scientific investigations presented in this paper, AE technology was used to differentiate different sand contents of hydraulic material flows. Differentiation of the different sand contents using interval analysis of the AE signals was possible in a laboratory environment. These results provide a basis for further investigations of more complex material flows consisting of water, sediment and polymetallic nodules.
