Compressed air is often used for heat absorption while it is expanded into its surroundings. Just for this property, it is widely taken as an effective means to improve the underground deep well ventilation. Based on their detailed calculation and analysis of the cooling effect of the compressed air in a hot mining work face, the authors have established a quantitative relationship between the air amount and pressure and the temperature reduced effect in the face. An economic evaluation of the effect caused by the underground temperature reduction is also discussed. Thus, it can be concluded that the temperature reduction by means of compressed air remains an efficient choice for deep well cooling practice in China's context at present stage.

压缩空气是矿山井下常用动力 ,它具有膨胀吸热的特性 ,因而可用于改善井下作业环境与气候条件。通过对矿井压缩空气吸热量的计算 ,分析了压气对井下热工作面的降温影响 ,并获得了压气与工作面降温效果的数学关系。还对井下采用压气降温进行了经济评价 ,指出了压气降温仍为我国深井局部降温的一种可供选择的好方法
