Abstract: Based on the basic data,well-test data and others of the coalfields in four large national coal planning mining areas of Jincheng,Yangquan,Xishan and Liliu,a comparison evaluation was conducted on the major reservoir physical properties of the coalbed methane. The study results showed that the coalbed methane in Jincheng and Liliu mining areas were good in enrichment and permeability and the gas content of the seams in Yangyuan Mining Area and Xishan Mining Area were low and the permeability was poor. The statistic results of the reservoir pressures showed that the reservoirs in Jincheng,Yangquan and Xishan Mining Areas were generally under pressure,the pressure status of the reservoirs in Liliu Mining Area was normal and meanwhile the fluid system of the multi seams in each mining area would be in difference. The calculation results of the underground water closed index in the coal measure strata showed that the closed index of Liliu Mining Area was max and the closed index of Xishan Mining Area was min. The min closed index showed an open fluid system and would not be favorable to keep the enrichment of the coalbed methane. The difference of the reservoir physical properties in each mining area would make the time parameters and space parameters of the “three block linkage” in the coal and coalbed methane coordinative development to be properly adjusted.
