Abstract In order to access the information of fractural images accurately and comprehensively，the image processing based on partial differential equation is introduced. After discussing the theory of active contour without edges model，a modified C-V model based on the technique of image enhancement is processed in order to overcome the drawback of the C-V model. High quality binary images as well as effective characteristic parameters of coal with meso-cracks are obtained using the modified C-V model and quantitative disposal. It?s the foundation of the continued investigation，for instance the calculation of seepage and the damage of coal. The results showed that，for low contrast ratio and inhomogeneous gray meso-cracks images，the modified conventional C-V model is better than the C-V model in obtaining the image segmentation and the quantitative information which can be used for computing the permeability and damage factor.

Key words： rock mechanics modified C-V model meso-crack of coal image segmentation meso-information quantization
