Abstract:

According to statistic data, China's coal-bed gas resources are 30×10¹²～35×10¹²m³.Excepting the loss resulted from buried depth, metamorphism, gas weathering zones and coalfield structures, the actural recoverable coal-bed gas resources are only 10 ×10¹²m³.Based on the process of American coal-bed gas exploration, it is predicted that China's coal-bed gas production would be 0.43 ×10⁸～0.65 × 10⁸m³ in 2000 A.D., it will be 20 ×10⁸m³ in 2000～2010 A.D., 100×10⁸m³ in 2020 and in the year of 2050 A.D.., the production will be 2050 ×10⁸m³.
