摘要/Abstract

摘要： 确定井巷风流热量来源及关键地点温度变化、热增量与损失量，并以之为依据有针对性地开展深井气候调节是通风工程需要解决的关键问题之一.通过改进传统的傅里叶导热模型，建立了基于通风井巷实际断面形状的三维热传导模型，针对不同井巷断面形状确定了反映流速与流量状态的动量相关的计算边界条件，并结合时间参数揭示了岩层内部导热以及井巷岩壁与气流间的热交换规律，建立了湿壁面与气流间的热湿传导方程.在此基础上，构建起国内某大型深井金属矿山井下通风系统，获得了关键地点的温度、湿度、热量等参数的走势和变化特点，为矿山开展深井气候调节与控制奠定了基础.

Abstract: It is a critical issue to adjust and control the subsurface mine climate based on the heat sources in airway and the temperature changes， heat gain and loss of key locations. By improving the traditional Fourier heat transfer model， a three-dimensional heat transfer model based on the actual cross-sectional shape of the ventilation airway was formulated. The momentum related boundary conditions which can reflex the velocity and quantity changes for different airway profiles also was specified， which associated with the time parameter to reveal the formation of heat conduction and exchange inside the strata and between the rock and airflow， and the heat transfer equation between wet wall and airflow was given at the meantime. On this basis， a large domestic ventilation system for deep subsurface metal mine was built， in order to obtain the trend and specialty of temperature， humidity， heat and some other parameters. This study lays the foundation for the deep subsurface mine to carry out climate regulation and control.
