Micro Tunneling

As the name implies, microtunneling or microtunnelling is a digging technique used to construct small tunnels. These small diameter tunnels make it impossible to have an operator in the machine itself. ... Microtunnel boring machines are very similar to tunnel boring machines (TBM) but on a smaller scale. As the name implies, microtunneling or microtunnelling is a digging technique used to construct small tunnels. These small diameter tunnels make it impossible to have an operator in the machine itself. Instead, the microtunnel boring machine (MTBM) must be operated remotely.
