Tunnel Boring Machine

 · Bhawani Singh, R.K. Goel, in Engineering Rock Mass Classification, 2011. Introduction. Tunnel boring machines (TBMs) have extreme rates of tunneling of 15 km/year and 15 m/year and sometimes even less. The expectation of fast tunneling places great responsibility on those evaluating geology and hydrogeology along a planned tunnel route.
