Tunnel boring machine - Wikipedia

A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through anything from hard rock to sand. Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drillingra

Jan 01, 2012  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.

Tunnel Boring Machines (TBM) – Roadheaders (TSM)

Tunnel boring machines, together with shield machines (SM), belong to the category of tunnel boring machines (TBM).
