The invention discloses coal water slurry prepared by mixing gasified coal with petrochemical wastes. The coal water slurry is prepared from the following components: coal, the petrochemical wastes, additives and water, wherein the mass of the petrochemical wastes accounts for 0-6% of the total mass of the coal water slurry but not zero, and the adding amount of the additives accounts for 0-0.15% of the total mass of the dry coal but not zero. The invention also discloses a slurrying technology of the coal water slurry. The coal water slurry provided by the invention is good in fluidity and stability. 本发明公开了种气化煤掺混石化废弃物的水煤浆，其组分包括煤、石化废弃物、添加剂和水，其中所述石化废弃物占水煤浆总质量的0～6％但不为零，所述添加剂添加量为干煤总质量的0～1.5‰但不为零。本发明还公开该水煤浆的制浆工艺。本发明提供的水煤浆流动性和稳定性好。
