| Abstract: | Efficient resource utilization and environmental protection place significant demands on the development of high-concentration Coal-water slurry. The rheological properties of this slurry are crucial to its performance during transportation, storage, and combustion. Coal-water slurry, essentially a non-colloidal suspension with a high-volume concentration, is significantly influenced by interactions at the solid/liquid and solid/solid interfaces, which in turn affect its rheological behavior. Understanding these interfacial interactions provides insights into the mechanisms governing its macroscopic properties from a microscopic perspective. This paper begins by examining the composition of Coal-water slurry and summarizes how various factors, including Coal characteristics (such as type and particle size), the liquid phase (composition and fluidity), and different dispersants, influence its interfacial behavior. It also reviews the current research on the macroscopic rheological properties of Coal-water slurry and outlines potential future research directions. By gaining deeper insights into the microscopic interfacial properties of Coal-water slurry, we can enhance our understanding of its macroscopic rheology, ultimately contributing to the formulation of an optimized Coal-water slurry.
