Tunnel Boring Machine an overview ScienceDirect

2010-8-18  4.3.1.5 Slurry Tunnel Boring Machine. Slurry TBMs are used for highly unstable and sandy soil and when the tunnel passes beneath structures that are sensitive to ground disturbances (NFM Technologies, n.d.). Pressurized slurry (mostly bentonite) supports the tunnel face. The support pressure is regulated by the suspension inflow and outflow.

Tunneling Machines an overview ScienceDirect Topics

2012-1-1  7.8.3 Rock Boring. Because TBM tunneling produces a much smaller disturbed zone and requires much less rock support than the drilling and blasting method, more and more TBM machines are used all over the world. However, up to the present date the cost of TBM tunneling has been much higher than that of the drilling and blasting method.
