摘　　要：长距离管道水力输送技术在铁精矿输送领域逐步推广应用,其优势在应用中得到了较好的体现。镜铁精矿的长距离水力输送在世界范围内尚无先例,对其进行了试验研究和理论分析。镜铁精矿因其特殊的片状结构,沉降特性和流变特性与常规铁精矿存在较大差异,对实际应用带来较大不利影响。The long-distance hydraulic pipeline transportation technology is gradually popularized and applied in the field of iron concentrate transportation,and its advantages are well reflected in the application.There is no precedent for the long-distance hydraulic transportation of specularite concentrate in the world,and therefore it is experimentally studied and theoretically analyzed.Because of its special sheet-like structure,the settling characteristics and rheological behavior of specularite concentrates are quite different from those of conventional iron concentrates,which have a great adverse effect on practical applications.
