Beschreibung
Zusammenfassung:	A tunneling apparatus is disclosed. The tunneling apparatus includes a drill string formed by a plurality of drill string sections. The drill string has a proximal end and a distal end. The tunneling apparatus also includes a drill head mounted at the distal end of the drill string, the drill head including a cutting unit, a rotational driver that provides torque for rotating the cutting unit, and a thrust driver for applying thrust to the drill string. The tunneling apparatus further includes a vacuum system for withdrawing spoils generated by the cutting unit during operation of the tunneling apparatus and a drilling fluid system for providing drilling fluid to adjacent the cutting unit during operation of the tunneling apparatus. The tunneling apparatus includes a control system that allows an operator to select between a drilling mode and a break-out mode. The tunneling apparatus also includes a control interface that allows an operator to monitor vacuum pressure which concurrently controlling operation of various systems of the tunneling apparatus.
