A Closer Look at the Design of Cutterheads for Hard Rock Tunnel-Boring Machines

Jamal Rostami, Soo-Ho Chang

Engineering 2017, Volume 3, Issue 6,   Pages 892-904 doi: 10.1016/j.eng.2017.12.009

Abstract:

The success of a tunnel-boring machine (TBM) in a given project depends on the functionality of allno part of the machine plays a more crucial role in the efficient operation of the machine than its cutterheadThe design of the cutterhead impacts the efficiency of cutting, the balance of the head, the life ofOverall, cutterhead design heavily impacts the rate of penetration (ROP), rate of machine utilizationdesign, and the implications of the head design on machine operation and life cycle.
