摘　　要：根据大型模拟试验和现场实测结果，分析了粘性矿石的流动特征。针对溜井和矿仓悬拱和堵塞的生产问题，介绍防治途径，重点阐述了粘性矿石的促流技术和促流器的研究及其在溜井和矿仓中的应用。According to the large-scale modelling test and actual measurement result,the flow character of cohesive ore is analysed. Directing against hanging-arch and stop problems in chute and ore bin,the prevention and cure measures are put forward,particularly,the study on promoting-flow techniqueand promoting device of cohesive ore as well as their application in chute and ore bin are described.
