In order to stabilize the trajectory of buckets traveling on the sea floor for mining mineral resources, this study proposes a novel method to mine these mineral resources with traveling buckets whose trajectories are straight and predictable with the use of two axially moving belts. ... A concept design of the two-belt continuous line bucket ...

We propose a system configuration where the excavating function is realized by a machine and the transporting function is realized by another machine. "Continuous mining" adopts the similar approach [22], [23]. It is composed of continuous excavating machines fixed at draw points and conveyer machines fixed at drift.
