Based on the data of the exploration and development from some vertical CBM wells in the Fanzhuang blocks of the Qinshui Basin, the enrichment evaluation indicators system of CBM was established according to the enrichment factors of CBM, and three types of enrichment degree in the block was distinguished using multi-level fuzzy comprehensive evaluation method. According to the basic principles of structural curvature and combining with the actual data of the block, the prediction method of the coal reservoir permeability on structural curvature was set up.
