巷道围岩与风流热交换的理论研究是矿内空气热力学的基础。这一工作的开展对深井降温技术实践和地热能源的利用都有指导意义。本文的主要目的在于给出求算非稳态热交换过程中,任一时刻水平巷道围岩内岩温径向分布及巷道中风温沿轴向分布的方法。为解决工程实际问题(诸如:冷却方式的选择,地温利用中预热暴露面积的确定等)提供理论依据。水平巷道围岩与风流热交换的研究内容
The theoretical study on the heat exchange between roadway rock and air current is the basis of air thermodynamics in mine. The work carried out on the deep well cooling technology and geothermal energy use are instructive. The main purpose of this paper is to find out the method of calculating the radial distribution of rock temperature and the temperature distribution of the tunnel roadway in the horizontal roadway at any time during the unsteady heat exchange process. In order to solve the practical engineering problems (such as: the choice of cooling mode, the use of geothermal preheating the exposed area determination, etc.) provide a theoretical basis.
