STUDY ON CHANGE LAW OF THERMAL DYNAMIC OF AIR FLOW AND THERMAL RESISTANCE IN HIGH TEMPERATURE AND HIGH HUMIDITY MINE

根据热力学、热流体学和流体力学等基本理论，结合高温、高湿矿井的风流运动特征，推导出适合于高温、高湿矿井的风流运动基本理论方程组，并引入热阻力概念及推导出热阻力的计算公式．最后，结合某高温工作面实测参数进行分析，进一步说明了高温、高湿矿井中热湿源对风流运动的影响不可忽视．

According to the fundamental theory of thermodynamics, thermal fludics and fluid mechanics, combined with the air flow moving characteristics, the coupled equation of fundamental theory which is suited to air flow movement in high temperature and humidity mine is derived, thermal resistance concept is led in and the formula for calculating thermal resistance is derived. Finally, conduct analysis combined with actual measured parameters from a working face with high temperature and further shows that the influence on air flow movement of thermal and humidity source in high temperature and high humidity mine should not be ignored.
