This paper introduces the application of ventilation technology in the underground station of Jinchuan Nickel Mine No. 2 mine. The industrial experiment of ventilation technology is carried out. It is clarified that the grade Ⅱ, Ⅲ and Ⅳ stations in the ventilation system of the multi-station of No. 2 mine are frequently destroyed, In view of the existing problems, drawing on the mature experience of ventilation technology in the first-stage production of No.2 mine, this paper put forward a series of technical reformation and practice Proved to meet the ventilation needs of underground work area, and achieved good economic and social benefits
