| 1 | Resources Conditions of Coalbed Methane Districts in China显示文摘The China National Administration of Coal Geology accomplished an assessment of coalbed methaneresources of China in 1988. The total amount of coalbed methane resources in China is 14336.944 billion m , occurring in recoverable coal seams and beneath weathering zones, with coalbed methane content equal to or higher than 4 m3 per ton and buried depths smaller than 2000 m, among which there are 967.51 billion m of predicted reserves and 13369.434 billion m of future reserves. The resources in coal reservoirs with methane content of more than 8 m per ton are 12444.087 billion m , and those with methane content between 4 to 8 m per ton are 1892.856 billion m . There are 35 districts in which the resources abundance is higher than 150 million m3 /km2 , 49 districts with the abundance between 50 million and 150 million m 3/km2 , and 31 districts with the abundance less than 50 million m3 /km2 . There is 9256.078 billion m3 of methane occurring in coal seams with buried depths less than 1500 m, and 5080.866 | TANG Shuheng LIN Dayang | 2000 | Acta Geologica Sinica(English Edition)2000，74，3： | 4 |
| 2 | Characteristics of Coalbed Methane Resources of China显示文摘The paper deals with the coalbed methane gas-bearing characteristics such as the gas content, theoretical gas saturation, gas concentration and abundance, as well as coal reservoir characteristics such as the adsorption, desorption and permeability of China’s coal reservoirs. The paper also introduces the resources of coalbed methane with a gas content ≥4 m3/t and their distribution in China. | LIN Dayang YE Jianping QIN Yong TANG Shuheng | 2000 | Acta Geologica Sinica(English Edition)2000，74，3： | 0 |
