Prediction of Rock Temperatures and Water lnflow Zones in Deep Tunnels

In deep tunnelling/mining the knowledge of in-site rock temperatures is of paramount importance, e.g. for planning of the underground operabons or for the design of ventilation. During construction large water inflows from karstic or fracture zones can lead to disastrous geotechnical problems. In the following, examples will be presented to predict rock temperatures and water inflow zones.
