Knowledge of the geomechanical state of the rock mass surrounding the heater and identification of changes in rock properties induced by the experiment

The report (deliverable) on the geomechanical characterization of the rock mass around the heater described:
The applied methods, the information achieved,
The relevance of the results for the characterization of the EDZ around the heater,
The experiment-induced changes.

Static and dynamic moduli were derived from velocity measurements and dilatometer tests. Video inspection and caliper measurements give information on the overall stability of the boreholes and the existence of open fractures.

All results were analysed and compared, to get reliable information on the geomechanical state of the rock mass close to the heater after the experiment. The results enable the optimization of future measurements.
