ABSTRACT:
A device for mining the bottom of a body of water for ores and minerals, having a flexible combined guide train and conveying train assembly suspended between a drive unit on board a ship and a receiving unit. The latter is towed along the bottom, so as to scrape or scoop up the wanted materials, by means of the resiliently stretchable combined train assembly. This assembly comprises synthetic rope strands in both the guide train assembly and the conveying train, guide units being spaced along the guide train assembly for the interference-free guidance of the conveying buckets attached to the multiple strands of the conveying train. The receiving unit, equipped with various monitoring sensors, is also linked to a buoy, by means of which it can be raised for transport and repositioning.
