地下下降(jiang)800米溫度(du)(du)升(sheng)高(gao)至37度(du)(du)左右，地下礦井(jing)坑道(dao)作業條件惡劣(lie)，溫度(du)(du)較高(gao)，有毒有害氣(qi)(qi)體，空(kong)氣(qi)(qi)不流通。使用片(pian)冰機對礦井(jing)降(jiang)溫是常(chang)見方法之一，簡單方便，能夠持續為礦井(jing)降(jiang)溫。

片冰機在煤礦礦井的作用：

　　煤礦礦井(jing)容(rong)易(yi)產生瓦斯易(yi)燃氣(qi)體，一旦礦井(jing)溫度升(sheng)高容(rong)易(yi)爆炸，礦井(jing)垮塌嚴重(zhong)的安全事(shi)故，片冰降溫可避免(mian)易(yi)燃氣(qi)體爆炸。

　　礦井(jing)降溫，保(bao)障機器(qi)、工作人員舒適的環境

　　溫(wen)(wen)度高，機器容(rong)易故障。工(gong)(gong)作(zuo)(zuo)人員(yuan)容(rong)易中(zhong)暑等。氣(qi)溫(wen)(wen)每增加1℃，礦(kuang)井生(sheng)產效率則降低6-8%。在-800m以下的采掘工(gong)(gong)作(zuo)(zuo)面，夏季三個月份，回(hui)采工(gong)(gong)作(zuo)(zuo)面突破(po)30℃，煤(mei)巷(xiang)掘進(jin)工(gong)(gong)作(zuo)(zuo)面溫(wen)(wen)度高達(da)32℃、33℃，濕疹和(he)中(zhong)暑等現象時有發生(sheng)，嚴重影響了職工(gong)(gong)的身心健康(kang)和(he)安全生(sheng)產，并(bing)對機電(dian)設備造成(cheng)損害，影響生(sheng)產效率和(he)施工(gong)(gong)安全。人是(shi)企業(ye)之本，防(fang)暑降溫(wen)(wen)是(shi)煤(mei)礦(kuang)職業(ye)病防(fang)治(zhi)工(gong)(gong)作(zuo)(zuo)的重要內容(rong)，是(shi)安全生(sheng)產的基礎(chu)工(gong)(gong)作(zuo)(zuo)。
