| 摘 要： | 首先探讨了矿井应用压缩空气膨胀降温手段的适用范围,在此基础上,与直接应用压气降温回采面的方法进行了比较。本文着重对压气在一段巷道中的降温效果进行了分析。具体探讨时,以压气膨胀为研究对象,针对其在热传导公式中的不同作用,采用两种方法研究膨胀降温效果。最后对通风降温和膨胀降温进行了经济分析,并给出综合实例。

| Abstract: | The paper first probes into extent of application of using compressed air expansion method to lower the temperature in mine,and then compares with the method of directly using air produced by air compressor to cool mining face.The paper mainly focuses on a section of tunnel to analyze the influence of expansion of air produced by air compressor to temperature in mine.Two different thoughts are used in analysis and heat conduction formula is applied,on which an equation of effect of expansion of air produced... |
