In order to guarantee the safe and efficient production of coal mine of Huoerxinhe Company, for the problems of gas exceeding limitation, excavating replacement tension, resource waste air leaking and so on, the ventilation mode was optimized and Y type ventilation mode was adopted. Practices indicate that this ventilation mode is entirely feasible on working face of Huoerxinhe Company. Through this mode, we can (1) decrease the tunneling engineering quantity, improve the excavating replacement tension of double U type mode; (2) reduce the protective coal pillars to cut down resource waste; (3) solve the problem of gas exceeding limitation on upper corner thoroughly.
