| Abstract: | Atomic force microscope (AFM) is used in studying coal surface structure. A method for studying this structure is proposed in mesoscopic scale. Base on fractal theory and the observation result by AFM,the fractal dimension D is calculated. It is found that there is obvious fractal characteristic. During the calefactive oxidation process of coal,the value of fractal dimension increases when the oxidation temperature increases. |
| Keywords: | coal mesoscopic scale fractal dimension islet method calefactive oxidation |
