通风障碍物作用下独头巷道热环境数值模拟研究

Numerical Simulations of Thermal Environment in the blind heading of metal mines

当前深部矿井高温高湿问题已变得愈加严峻,本文采用CFD数值模拟软件对金属矿山采场的独头巷道进行热环境数值模拟研究,建立了铲运机等通风障碍物存在情况下的巷道几何模型,通过改变风管出风口风速,探讨了不同送风速度对巷道热环境的影响规律,为通风降温能耗优化提供理论基础。

At present,the problem of high temperature and humidity in deep mines have become more and more severe.In this paper,CFD numerical simulation software is applied to simulate the thermal environment of the blind heading in a metal mine.The geometry model of the airway is established under the existence of ventilation obstacles such as LHD.By changing the airflow velocity of the air duct,the different airflow is discussed.The effect of speed on the thermal environment of the airway provides a theoretical basis for the optimization of ventilation and cooling energy consumption.
