Abstract: In this paper, through the analysis of coal seam gas production situation in Western Chengzhuang Minefield, combined
with the characteristics of coalbed methane, lithology of roof and floor rocks, the development of the fractures, the reservoir
pressure, absorption characteristics and the recovery factor, and the main geological factors affecting coalbed methane production
capacity are expounded to provide the basis for coalbed methane in Chengzhuang Minefield mining. Key words: Chengzhuang Minefield; coalbed methane; production capacity
