Permafrost takes place approximately 35 million km\(^2\) of the globe land. In Russia, it is most widely distributed in Eastern Siberia and Baikal region with oil and gas fields. Exploitation of the fields promotes the permafrost melting because of different technical devices affect on the dynamics of thawing. The permafrost thawing due to various human-generated impacts will be accompanied by subsidence of the earth’s surface around engineering facilities and development of dangerous permafrost geological processes, called thermokarst, which can lead to accidents in oil and gas fields with great damage to the environment. Therefore, an important problem for computer simulation is prediction of dynamics of the permafrost boundaries changes under long-term thermal impact of technical systems operating. In the paper a model and an algorithm for solving the problem of propagation of thermal fields in frozen ground from horizontal flare systems operated under a special regime are proposed. The maximum number of climatic and technical parameters is taken into account in the simulations. The calculations allow to choose an optimal thermal insulation of the ground surface under the flare system.
