A tunnel boring machine ( TBM ), also known as a "mole", 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".
Una tuneladora o Tunnel boring machine (TBM por su denominación en inglés) es una máquina capaz de excavar túneles bajo tierra a sección completa, es decir, en una sola operación mecánica, mediante la perforación. Suelen pesar más de 6.000 toneladas y alcanzar más de 150 metros de longitud; y trabajan en terrenos variados, desde rocas ...

Learn how a tunnel boring machine (TBM) works, what are its advantages and drawbacks, and what are the different types of TBMs. A TBM is a device that excavates tunnels in hard or soft rock using a rotating cutterhead and a thrust system.
From the design and stabilization of the cutterhead to the rapid removal of muck, we know what it takes to manufacture the most efficient tunneling machines. That’s why Robbins TBMs have been used on more rock tunnels than all of the competition combined. Robbins TBM owners have set world excavation records for virtually every tunnel diameter.
