A tunnel line (16) of a tunnel to be excavated is determined e.g. by using curve fitting.
A location of a drilling site on the tunnel line is communicated to the control unit (11) and a navigation plane (19) of the drilling pattern (28) is positioned on the tunnel line.
A start point (30) of a round is positioned on the tunnel line (16) and a length (L) of the round is provided.
Wittke et al. (1972) describe the application of a finite-element model to a tunnel line in jointed rock.
