乌克兰煤炭工业部各矿井正在使用四千多台刮板输送机。使用经验表明,刮板输送机产生事故的一个主要原因是由于煤粉和岩粉落入溜槽而堵塞回空链。产生事故的直接原因如下:在转载点处由于输送机之间的间隙太小;工作面有地质断层和底板起伏不平;推移输送机之前未清扫浮煤;使用已经磨损的链条时刮板相对连接环发生垂直位移。在条件较差的情况下,落入输送机下部 Coal mines in Ukraine’s Ministry of Coal Industry are using more than 4000 scraper conveyors. Experience has shown that one of the major causes of accidents with scraper conveyors is the clogging of the empty chain due to pulverized coal and rock dust falling into the chute. The immediate causes of accidents are as follows: at the transfer point, the gap between the conveyors is too small; the work surface has geological faults and the bottom plate is uneven; the floating coal is not cleaned before passing the conveyor; the scraper is relatively connected when the worn chain is used Vertical displacement of the ring. In poor conditions, fall into the lower conveyor
