摘　　要：讨论四种烟煤的岩相显微组成与它们制成水煤浆时成浆性的关系，试验指出在煤的灰含量基本相同情况下，煤的岩相显微组成中镜质组和半镜质组含量高、丝质组含量低时对增加水煤浆的煤浓度、增加煤浆结构稳定性及减少煤浆粘度有利。This paper discusses the relationship between petrographic macerals and slurrying ability of coal in producing CWS.Experiments have proved that more vitrinite and semivitrinite and less fusinite in coal petrographic macerals is beneficial to the slurrying ability of CWS.i.e.to increasing coal concentration,stability,fluidity and decreasing its viscosity under same ash content of coal.
