Abstract: With the rapid development of domestic CBM industry in the past ten years,in order to further grasp the situation of CBM resources,the evaluation work on the shallow CBM resources above 2 000 m of the 30 major coal-bearing basins was re-evaluated.The previous main methods and achievements had inherited and updated during this round of evaluation,mainly based on the volume method,and carried out in the order of the calculation unit-zone-basin hierarchy.The CBM resources in the country was classified in several aspects according to the regions,coal ranks,burial depths,and coal series.The evaluation results showed that the geological resources of shallow CBM above 2 000 m were 29.82×1012 m3 and the recoverable resources were 12.51×1012 m3.For the first time,the anatomical areas of Fanzhuang,Sanjiao,and Baode were established,and the analogy method was evaluated to further implement the key parameters such as the gas content and the recoverable coefficient.It was also the first evaluation of the recoverable resources of shallow CBM from 1 500 m to 2 000 m.The study has obtained the latest results of CBM resources in China and clarified the distribution of CBM resources in China.
