Rheological properties of coal-oil mixture (COM) was studied. The viscosity of COM was measured by changing the coal concentration, temperature, water content, and stabilizing agent. Non-Newtonian properties of 40 Wt% and 45 Wt% coal COM was investigated by oaring the water concentration at 70℃. The viscosity variance vs temperature was well fitted with the equation μ=C₁t^(C₂), and the viscosity corresponding to the volume concentration of coal was also well fitted with the Thomas relation. The COM including water showed non-Newtonian characteristics of pseudoplastic model.
