Abstract：Shouyang Area located in the north part of Qinshui Basin ,Shanxi Province was one of the major coalbed methane exploration and development blocks in the recent years.With the comprehen‐sive analysis on the coalbed methane potential of the area ,the gas drainage data of the coalbed methane exploration well in the early stage of the mine shaft construction ,conservation status of the coalbed methane reservoir ,hydrogeologic condition ,gas drainage system and other factors ,there were four main control factors (including the gas drainage method ,gas drainage system ,gas influences and coal dust jamming) affected to the coalbed methane drainage effect of the area found.The paper provided the measures to improve the gas drainage effect.
