Abstract：The effects of coal property, oxide types and coal macerals on the slurryability were investigated by Spearman correlation, using different dispersants, furthermore, to study the matching rules between dispersant type and the above factors. The results show that, there are obvious differences for the correlation of these factors on the slurryability using different dispersants. The ZFZ and JSS dispersants have better matching with the high rank coal, but the NHS and MZS dispersants are beneficial for improving the low rank coal slurryability. Meantime, the NHS and JSS dispersants are also useful for improving the slurryability, when the difference values between the content of inertinite and vitrinite are greater in coal. In addition, SiO2 , Al2 O3 , CaO are negatively correlated with slurryability.
