Abstract The equation of heat conduction in a heterogeneous environment is being studied. An approximate method was developed for calculating the thermal conductivity of layered soil. Priori estimates were obtained to solve the direct and conjugate problems of difference. We prove the limitation of approximate values of the thermal conductivity coefficient. Numerical calculations were aimed to test the convergence of iterative calculative scheme of the thermal conductivity of the soil. Keywords: dispersion environment, equation of heat conductivity, inverse problem, dual problem, priori estimates, thermo physical characteristics of the soil.
