Analysis on Numerical Simulation of Mine Thermoregulation with Thermal Tube Bolt in High-Cold Area

为了提高井巷围岩对空气的热交换率,分析了热管锚杆工作原理,建立了热管锚杆数值模型,并进行了热管锚杆导热的数值模拟。结果表明,采用热管技术与井下大量使用的锚杆相结合的基本方法,在一定程度上可以实现矿井空气温度的自我调节功能,为高寒地区矿井空调工作提供新的理论基础和技术支持。

In order to improve the heat exchange rate of roadway surrounding rock to air, the working principle of heat pipe anchor was analyzed, the numerical model of heat pipe anchor was established, the numerical simulation on heat conducting of heat pipe anchor was conducted. The result shows that, with the application of common anchor combined with heat pipe technic, to some extent, the self- adjustment of air temperature can be realized in mines, providing new theoretical foundation and technical support for the mine air - conditionin~ work in extremely cold re.inn
