摘　　要：为了分析水平巷道通风降温的适用性,运用理论分析、现场试验和数值模拟的方法对水平巷道通风降温的适用风量及影响因素进行了研究,建立了水平巷道通风降温适用风量的数学模型,并依据夏甸金矿一水平巷道热环境参数验证了模型可靠性。研究结果表明:巷道热物理参数确定时,适用风量增加幅度随入风温度的增加而增大;当入风温度和风量不变时,出口风温随壁温的增加呈近似线性增加,壁温越高时出口风温下降幅度越大,因此较大风量对严重热害区域的降温效果较好。通风降温效果上,降低入风温度比增加风量效果更好。In order to analyze the applicability of ventilation and cooling in horizontal roadway,theoretical analysis,field test and numerical simulation were used to study the appropriate air volume and influencing factors of ventilation and cooling in horizontal roadway,and the mathematical model of appropriate air volume for ventilation and cooling in horizontal roadway was established.Then,the reliability of the model was verified according to the thermal environment parameters of a horizontal roadway in Xiadian gold mine.The results show that,when the thermal physical parameters of roadway are determined,the increase range of appropriate air volume increases with the increase of inlet air temperature;when the inlet air temperature and air volume remain unchanged,the outlet air temperature increases approximately linearly with the increase of wall temperature,and the higher the wall temperature,the greater the decrease range of outlet air temperature.Therefore,the larger air volume has a better cooling effect on severely hot areas.In terms of ventilation cooling effect,reducing the inlet air temperature is better than increasing the air volume.
