摘　　要：煤矸石的传统运输方式存在运力有限、运输成本高、转运过程产生污染的问题,影响其综合利用进程。从煤矸石综合利用制砖的角度,采用管道输送的方式转运煤矸石浆体至用户。通过对实验室制备的煤矸石浆体进行基础特性参数、流变特性参数测定、分析,得到浆体的管道输送特性参数数据,及其与浆体粒度分布、重量浓度之间的关系,研究成果可指导工程设计。The traditional transportation mode of coal gangue has the disadvantages of limited transportation capacity, high transportation cost and pollution in the transportation process, which affects the comprehensive utilization process. Starting from the utilization mode of coal gangue brick making, the coal gangue slurry is transported to users by pipeline transportation. Based on the measurement and analysis of the basic and rheological parameters of coal gangue slurry prepared in the laboratory, the pipeline transportation characteristic parameters of coal gangue slurry are obtained, and the relationship between the parameters and the particle size distribution and weight concentration of the slurry is obtained. The research results can guide the engineering design.
