Abstract in order to solve the problem of insufficient air distribution in Zhenchengdi Mine, the 22605 working face of the mine was taken as the research background, and the effect of circulating ventilation by using numerical simulation software was analyzed. It was found that the circulation ventilation can not only improve the ventilation of the mine, but also effectively eliminate the gas and dust in the working face, so as to meet the production needs of the mine. The technology provided reference for mine cost reduction and efficiency increase.
