The project was designed to study thermal energy flow in granitic rock (tonalite), both in terms of efficiency as well as safety. The results include in-situ and laboratory thermal experiments. In the frame of an in-situ experiment, a study of thermal stress was carried out in the underground laboratory Josef in Czech Republic. Stress changes in rock environment induced by cyclic thermal loading at 120 m depth were continuously monitored in order to evaluate the influence of the thermal load increments. Tonalite cores were subsequently tested in laboratory. Cylindrical samples were heated in servo-hydraulic loading frame to obtain the stress response and monitor acoustic emission activity. A detailed P-wave ultrasonic sounding on spherical samples was used to evaluate the extent of heating induced damage.
