CBM resources and economic evaluation lay a foundation for CBM development. On the basis of gas geology theory, this article presents a quantitative and qualitative analysis of the relationships between coal-bed gas content and geological factors, including geological structure, buried depth, elevation of seam floor, thickness of upper bedrock, roof and floor lithologic characters, seam thickness, figuring out the distribution law of CBM—more in the east and south, less in the west and north.
