Abstract

In this article, surface and pore size analysis, FTIR spectroscopy, XPS spectroscopy, wettability test are applied to study the influence laws of particle size on coal dusts' surface characteristic and wettabiligy.The research shows that the coal dust surface structure, chemical composition and elements composition changed with the decrease of the granularity of coal dust. In the same time the coal dust also shows weaker hydrophilic and stronger hydrophobic.
