Tunnel boring machine - Wikipedia
A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. Tunnels are excavated through hard rock, wet or dry soil, or sand, each of which requires specialized technology. Tunnel boring machines are an alternative to drilling and blasting (D&B) methods and "hand mining".
Prufrock - The Boring Company
Prufrock is designed to “porpoise,” meaning it launches directly from the surface, mines underground, and re-emerges upon completion. This allows Prufrock to begin tunneling within 48 hours of arrival onsite and eliminates the need to excavate expensive pits …

Tunnel Boring Machine: Working of the Tunnel Construction …
A tunnel boring machine (TBM), also known as mole, is employed for the construction of tunnels in hard or soft rock strata. The cutting process utilizes the rotation of the cutterhead (geared with disc cutters) and the blade pressure for excavation on the face of rock.

The Evolution of Tunnel Boring Machines - by Brian Potter
2023年10月6日 — TBMs have evolved along two parallel paths of technological development. The first is the development of machines for tunneling through soil and soft ground, and the second is machines for tunneling through rock. Today, machines of both types get categorized as tunnel boring machines, and the lines between them are sometimes blurry.
Tunnel-boring machine: how does it work, types and …
A tunnel-boring machine (TBM) is a machine that can dig full-face tunnels underground; this means it is done in a single mechanical operation by drilling. They usually weigh over 6,000 tons and span more than 150 meters in length, and they work in a variety of terrains, from sedimentary and volcanic rock to sandy or clay soils.
