| Abstract: | Using industrial CT scanning equipment, sample coring and microscopic scanning analysis of high quality anthracite in Zhaogu No.1 Mine were carried out. The original image is denoised, enhanced, and binarized by image processing technology. The image information is accurately expressed by threshold adjustment. Finally, the CT image was reconstructed by Avizo software to obtain a three-dimensional fracture structure model. The results show that the three-dimensional digital coal core reconstructed by industrial microscopic CT scanning can accurately reflect the internal fracture structure of the real coal core. Image fine processing can accurately characterize the complex fracture network in coal samples and meet the requirements of quantitative description. |
