The thermal conductivities of basalt beds with different particle size were calculated by means of calculation and experiment respectively.The experimental and calculation results show that the thermal conductivity of basalt bed increases linearly with temperature.When the temperature is low, The thermal conductivity of the smaller basalt bed is larger than the thermal conductivity of the bed with the larger particle size.With the increase of the temperature, the thermal conductivity of the small particle bed begins to be less than the thermal conductivity of the large bed.According to the experiment The results show that the thermal conductivity of basalt bed is linear regression formula.The calculated results are consistent with the experimental results, the difference between the two is not significant, and the calculation method is feasible.
