摘　　要：针对羊场湾煤矿井下高温热害情况较为严重的问题,分析了国内外煤矿井下降温技术,研究了井下局部制冷降温技术的工作原理、系统组成。在羊场湾煤矿Ⅱ020203综放工作面进行现场应用,结果表明,采用局部降温技术后,该工作面的温度平均降低3~4℃左右,湿度降低了75%左右,工作面使用制冷机后降温、除湿效果较为明显,作业环境舒适度大大提高。In view of the serious underground high temperature heat hazard in Yangchangwan Coal Mine, the underground coal mine cooling technologies of home and abroad were analyzed, and the working principle and system composition of the underground local cooling system was studied, which was applied in 020203 fully mechanized top-coal caving face of Yangchangwan Coal Mine. The results show that, local cooling system, the working face average temperature reduced 3 - 4℃, humidity reduced by about 75%, achieving significant cooling and dehumidifying effect, and great improvement in comfort level of working environment.
