摘要：Wettability of coal dust is the main factor affecting wet dust which is one of the main dust control technology of coal mine. Multiple stepwise regression methods are used to study the coal dust wettability affected by industry analysis, elemental analysis and surface oxygenic functional groups by using SPSS software. The results show that the most important factor affecting the coal dust wettability is the phenolic hydroxyl content on the coal dust surface and carbon content in coal dust. The complex correlation coefficient for optimal regression equation is 0.943 and the optimal regression equation is = 35.042- 10.780(phenolic hydroxyl) + 0.859 Wad (FC). © Atlantis Press, 2010.
