Rock massif temperature changes measurement with regard to thermal responses generated by a thermal response test device

In this article are presented results from application of fiber optical DTS system within long term research of temperature energy accumulation in Paskov rock massif. In this area was established special measuring station for that purpose, because rock massif in Paskov area has ideal properties for temperature changes measurement. The twelve geothermal boreholes were drilled during this research, which were then used for rock massif heating by Thermal Response Test device. With the help of DTS system was observed how the temperature distribution and penetration in between boreholes in rock massif is. Thanks to the DTS system we were able to determine the Thermal Response Test device heating power influence on the nearest monitoring boreholes.
