Tunneling: What are the drilling methods?

A tunnel boring machine (TBM) – also called a "mole" – is a complex machine used to create tunnels, usually with a circular cross-section (other cross-sections are also possible), through various layers of soil and rock. It can also be used for so-called microtunneling. Tunnel boring machines can be designed to work in any material ...
