The preparations of stable and nonviscous deashed coal-water slurry (CWS) with water-soluble polymer and surface active agent have been studied. The effects of species of polymer and surface active agent, polymer concentration, and deashed coal concentration on the settling stability and fluidity of CWS were experimentally determined. It was found that the most desirable polymer for producing both settling stability and fluidity of CWS was the equivalent Xanthangum-Locust bean gum mixture (X-LB (1 : 1) mixture), which forms aqueous solutions exhibiting significant yield value at low concentrations. By addition of the correct ammount of X-LB (1 : 1) mixture and using suitable surface active agent, a practical static stability can be developed in most CWSs, but normally with some sacrifice in fluidities depending on coal concentration.
