The invention discloses coal water slurry and a preparation method thereof, and belongs to the technical field of chemical industry raw materials. The coal water slurry comprises the following components in parts by weight based on the total mass of the coal water slurry: 70-80 parts of coal powder, 20-30 parts of petroleum coke and 20-30 parts of water, and further comprises an additive, wherein the content of the additive is 0-0.15% of the total mass of the coal powder and the petroleum coke, but is not 0, and the additive is prepared from a methylene naphthalene sulfonate-styrene sulfonate-maleate high-molecular polymer, sodium lignin sulfonate, sodium hydroxide, hydroxyethyl cellulose and sodium polyacrylate. The obtained coal water slurry is high in coal slurry concentration, low in 24-hour bleeding rate, good in stability, free of hard precipitation and good in stability and flowability. 本发明公开了一种水煤浆及其制备方法，属于化工原材料技术领域。本发明所述水煤浆，以水煤浆总质量计，包括以下重量份的组分：70-80份煤粉、20-30份石油焦、20-30份水，所述水煤浆还包含添加剂，添加剂的含量为煤粉与石油焦总质量的0-
