Abstract: In order to accurately grasp the temperature change of surrounding rock in a full cycle of ventilation in the mine tunnel and do economic evaluation studies on it on this basis, in this paper, based on Fourier heat conduction law, the numerical model was established by Abaqus software and the finite element method was used to study the process of surrounding rock and air heat exchange and the temperature distribution of surrounding rock in the tunnel, the amount of cold and heat storage and the storage law of the surrounding rock of roadway were obtained. After that, the economical evaluation of the heat transfer capability of surrounding rock was carried out by using the equivalent air conditioning method. The results show that the surrounding rock of the mine has great economic advantages, and can further try to carry out the engineering practice in the future.
