Abstract: With the increase of mining depth and further the continuous increase of geotemperature, the heat exchange between laneway wallrock and airflow takes an increasing proportion.The study of this heat exchange law in normal circumstances is of great significance to the underground heat source analysis and airflow temperature forecast.Based on the theory of cooled zone, a mathematical model for the heat exchange between the inclined laneway wallrock and airflow, without considering the wetness exchange and other underground heat sources, was derived and its analytical solution obtained, which has been verified by the data practically measured in Jinqingding Mine area of Jinzhou Mining Group.

Key words: Inclined laneway, Airflow temperature forecast, Cooled zone, Heat exchange
