摘　　要：针对唐口煤矿1302采掘工作面的高温热害问题，结合理论分析和现场实测，对工作面气流温度场的分布规律进行了数值模拟，得出工作面的气流温度随送风温度的变化规律，并对采用冰冷空调系统后的降温效果进行分析，结果表明采用空调降温后，采煤工作面的温度平均降低4～6℃。To counter the heat hazard in 1302 working face of Tangkou Coal Mine,numerical simulation was carried out distribution law of air-flow temperature field according to the theoretical analysis and actual measurement at the site,the variation law of air-flow temperature in the working face with the supplied air temperature was obtained,and analysis was made on the cooling effect after using ice-cooling air-conditioning system.The results indicated that the temperature in the coal face was reduced 4~6 degree on average after suing air conditioning for cooling.
