To quantify the amount of defects in coke with low-quality coal, which were considered as one of the factors of coke strength, the fracture cross-sections were observed by a 3D scanning microscope (LSM) and the image recognition method was proposed. In the proposed image recognition method, the dark parts in the LSM image were identified as the pores, the rough parts excluding the pores were classified as non-adhesion grain boundaries, and the others were as coke matrices. As a result, the defects which were composed of both pores and non-adhesion grain boundaries, increased with the blending ratio of low-quality coal. Therefore, the image recognition method is expected as one of the quantification technique of defects in coke with low-quality coal.
