Abstract: In the base of determination of air-flow thermal parameters at Jinchuan No.2 mine，the variety regularity of airflow enthalpy，moisture content，relative humidity，dew point temperature and air density with airflow route，and the types and distribution of heat and humidity source at high temperature mine of Jinchuan No.2 mine are grasped.In the JinChuan No.2 Mine，the main heat source is self-compressed hot of air flow，heat dispersal of waste gangues in transportation，wall rocks and mechanical equipment in shaft；The main humidity source is the watering，the water gushing and the spraying for dust control in panel.In view of these heat and humidity sources，some control measures are put forward.

Key words: Thermal parameter, Enthalpy, Moisture content, Relative humidity, Heat and humidity source
