Abstract In order to solve the problem of large gas concentration in the mining area, 22208 working face of Zhenchengdi Mine was taken as the research background, and numerical simulation software was adopted to study the parameters of high drainage roadway arrangement, through the analysis, it showed that at the position of 38 m from the bottom of the roadway and 30 m from the air return roadway had the best gas extraction effect, which made a certain contribution to the safe mining.
