Abstract: In light of the reality of Jinqingding mining area of JinZhou Mining Group, a mathematical model for the heat and moisture transfer between wall rock and airflow was established. The comparison with the practically site-measured result shows that the incoming airflow temperature distribution obtained by the numerical simulation is very close to that practically measured, especially the change in depth and horizontal direction. It reflects the variation of the incoming airflow in a real stratum pre-cooling and temperature reducing system in an abandoned inclined shaft, discloses the law of heat exchange between wall rock and airflow, and proves the feasibility of the established prediction model in geotemperature reducing analysis and in the real design of a ventilation system.
