摘　　要：大采高工作面大块落煤往往比较严重,如果对于落下的大块煤不能及时破碎处理,会在刮板输送机机头处、转载机入煤口等部位堆积甚至堵死运输通道,导致停机等现场事故,需要人工处理停机事故,耗费大量的时间和人力物力,并制约煤矿安全高效生产。因此有必要对煤矿井下大块煤破碎装置进行研究。The large lump coal on the large mining height working face is usally serous.If not resolved urgly,there may cause block in the area of the head of the scraper corveyor and coal inlet of transfer machine,even blocking transportation channels,and will be causing machine stop.Resolving all these machine accident needs human involvement,and consumes a lot of manpower and resources,and will affect and restrict the safe and efficient production of the coal mines.Therefore,it is necessary to research the large lump coal crushing device in coal mine.

关 键 词：大块煤 破碎 堵塞 运输通道 高效生产
