In view of the lack of rock transport information at home and abroad, this article performs a back analysis on the slurry pump head and pipe coefficient of friction resistance based on delivery system principle and operational data of Asia’s first heavy-duty self-propelled cutter suction dredger Tian Jing Hao. On this basis, the paper verifies the applicability of the empirical formulas and gets the pipe coefficient of friction resistance of two kinds of rock, one is weathered and mixed with a lot of fine-grained component, and the other is weakly-weathered rock which is almost totally blocks. Considering the pipe coefficient of friction resistance varyend from the hard of uniaxial compressive strength, it is recommended to calculate the pipe coefficient of friction resistance by performing a back analysis on the rock conditions.
