12. A method for excavating a tunnel comprising:
providing an apparatus comprising:
a rotatable cutting wheel (109), with which an existing geology can be excavated in an excavation direction at the front on a tunnel face (118),
excavation tools (115) arranged on a cutting wheel face (112),
an excavation chamber (121) arranged on the back of the cutting wheel face (112) in the excavation direction, into which excavation chamber material excavated at the tunnel face (118) can be conveyed,
a discharge unit (127, 136), with which material present in the excavation chamber (121) can be removed, and
at least two measuring modules (151, 154, 157, 160, 163, 503) arranged on the cutting wheel face (112) and configured to record measured values characteristic of the consistency of material excavated at the tunnel face (118) and in that measuring modules (151, 154, 157, 160, 163, 503) arranged on the cutting wheel face (112) are configured to record different types of measured values,
recording of the measured values by the at least two measuring modules (151, 154, 157, 160, 163, 503) arranged on the cutting wheel face (112), and
conditioning the material present between the cutting wheel face (112) and the tunnel face (118) based on different types of measured values.
