埋刮板輸送機上竄下滑的趨勢：

  埋刮板輸送機之間上竄下滑是伴隨的，若前部刮板輸送機下滑，勢必造成后部刮板輸送機相對上竄，若前部刮板輸送機上竄，勢必造成后部刮板輸送機相對下滑。由于工作面前，后部刮板輸送機與工作面運輸巷轉載機轉載搭接不合理，勢必造成兩部刮板輸送機底鏈將煤炭帶入底槽，鏈斗輸送機 終出現刮板輸送機過載開不動，強行開車或倒車，從而導致刮板輸送機斷鏈條等機械事故出現。

  降(jiang)低了生產效率。工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)刮(gua)板輸送機上竄(cuan)下滑后(hou)，無論采取什么樣的措施，一方面(mian)(mian)增加了生產環(huan)(huan)節(jie)，另一方面(mian)(mian)影響產量(liang)。如(ru)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)兩端按(an)比(bi)例(li)調(diao)(diao)(diao)采，造成工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)一端推進困難，煤機開機率低，勞動組(zu)織(zhi)不合理(li)，不能按(an)正規循環(huan)(huan)作(zuo)(zuo)(zuo)業(ye)，減少循環(huan)(huan)數等(deng)。影響工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)工(gong)(gong)(gong)程質量(liang)，工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)刮(gua)板輸送機上竄(cuan)下滑后(hou)，必然要采取一定(ding)措施，如(ru)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)兩端按(an)比(bi)例(li)調(diao)(diao)(diao)采。這(zhe)就造成煤壁大線不直(zhi)，支(zhi)架調(diao)(diao)(diao)斜(xie)等(deng)問(wen)(wen)題，調(diao)(diao)(diao)整過程也是工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)(mian)工(gong)(gong)(gong)程質量(liang)容易出現(xian)問(wen)(wen)題的過程。
