This paper describes the operation of the tunnel boring machine (TBM) used to drive the French section of the Channel Tunnel. The paper makes a clear distinction between the two driving methods used in the tunnelling process: the open mode and the closed mode, the first being theoretically faster but slowed in practice by the spoil handling and disposal capacity. The tunnelling machines, of complex design, mobilized a large amount of computer-controlled and automatic equipment, also described in this paper. For the covering abstract see IRRD 866394.
