本文对浅部水平巷道地温预热的机理和技术作了系统的研究。根据差分原理结合电算给出了非稳态巷道围岩与空气热交换过程中的岩温径向分布和风温轴向分布及有关的预热参数。对预热机理提出了新的观点,并对合理利用地温及充分发挥预热效果的技术途径提出建议。
This paper systematically studies the mechanism and technology of ground preheating in shallow horizontal roadway. The radial distribution of rock temperature and the axial distribution of air temperature and the related parameters of preheating are given based on the principle of difference and the calculation of the heat exchange between surrounding rock and air in unsteady roadway. Put forward a new view on the mechanism of preheating, and put forward suggestions on the reasonable utilization of geothermal energy and technical ways of giving full play to the preheating effect.
