The paper deals with simulation of rock heating experiment in underground, testing the rock properties for geothermal application. The modeled process is unsteady heat conduction in 3D.

We made several parametric studies to find the possible temperature range with uncertainty in some of the parameters - in particular an interval around the laboratory measured heat conductivity and capacity and heat transfer coefficient of the rock surface, including a consideration whether to use an isolation layer on the tunnel face. Line profiles are selected to visualize the rate of temperature drop in various directions to efficiently choose sensor positions in the future experiment.
