矿井进风流与围岩的换热

The Thermal Exchange between Wall Rock and Mine Inlet Air

文章以热工学的基本原理和相关理论为基础,运用仪器对巷道进风流及巷道围岩周壁的温、湿度分布进行了测试。基于热传递的相关概念与机理以及矿内传热学基础,通过对巷道进风流与巷壁换热过程的分析,得出了进风平巷内风流与围岩间的对流换热系数和两者之间的潜热与显热交换之间的关系,并给出了相关的计算公式。

In the paper, on the basis of the basic principle and relevant theory of pyrology, the instruments are applied to test the inlet air and the temperature and humidity of the surrounding rock wall. Based on the related concepts and mecha- nism of the beat transfer and heat transfer theory basis and through theoretical analysis of thermal exchange process between the airflow of mine and the wall of excavation roadway, the eonvective heat transfer coefficient（CHTC） of the surrounding rocks and the wind flow and the relation of their latent heat and sensible heat is found out and the related calculation equa- tions are given.
