Features and development model of coalbed methane resources

In order to look for high efficiency development model of the CBM and prompt the development of the CBM resources,on the basis of summarizing the theoretical research results and exploration and development practical experiences, the author defines the CBM as the natural gas which is occurred in the coal seam and its surrounding rocks and is accompanied with the coal;the features of the CBM resources are generalized as two points:the adsorption state,and the self-generation and self-storage.According to the features of the CBM resources, this paper suggests the classification opinion on the development types of the CBM resources,of which the top class including the surface development,underground drainage,and the integration of the coal mining and gas exploiting,etc.
