ABSTRACT

This text deals with the dredging of rock by large cutter suction dredgers. The rock properties influencing the mechanical cutting of rock and the wear of cutting teeth are examined, and to verify the model of mechanical rock excavation developed, case studies of dredging projects were performed.
