Abstract：Thermal expansion and thermal conductivity instruments were used to measure the coefficients of thermal expansion(CTE) and thermal conductivity(TC) of Fushun oil shale in directions vertical and parallel to bedding. Experimental results were adopted in the simulation of thermal cracking based on the orthotropic assumption and one-way physical coupling. The CTE vertical to bedding was 1.69 times as much as that parallel to bedding，while the TC parallel to bedding was 1.83 times larger than that vertical to bedding direction. With the temperature increasing，the TC descended linearly while CTE fluctuated. KI varied when hydraulic fracturing dip changed，and KI reached the maximum when the dip was zero. The concept called the local effect during the thermal conducting was put forward to reflect the temperature distribution near the fractured area.
