The thermal conductivity of rocks varies depending on various factors. In this study, it is aimed to examine the factors affecting the thermal conductivity of rocks in detail. For this purpose; thermal conductivity measurements were carried out in different conditions in rocks and changes in thermal conductivity coefficient depending on porosity, water absorption coefficient, density, capillary water absorption coefficient, ultrasonic velocity and temperature were investigated. As a result; as temperature, apparent and true density, water absorption coefficient, capillary water absorption coefficient and P-wave velocity increase, thermal conductivity coefficient increases and decrease with increasing porosity. İn all samples, thermal conductivity coefficient increased between 5-12% depending on the temperature increase. The highest (0,993, K2E) and lowest (0,853, K2B) values of the correlation coefficient were obtained in moist samples. There are definite relationships between thermal conductivity and physical properties of rocks and the correlation coefficient in these relationships varies between 0,57-0,93 except temperature.
