The utility model relates to an auxiliary ventilation device for a non-coal mine, which belongs to the technical field of tunnel construction and comprises a steel rail and air duct cloth. The steel rail is fixed on a rock mass at the side part of the tunnel; the air duct cloth is mounted on the steel rail through a plurality of pulley units; and the pulley units are connected with the steel rail in a sliding manner. Before tunnel blasting, the air duct cloth is manually pulled to recover the air duct out of the blasting flying stone influence range, the fan is started after blasting, the air duct cloth is conveyed to the position near a tunnel working face through wind power, the situation that the air duct cloth is damaged or exploded due to blasting flying stone influence in the blasting process is effectively avoided, and the ventilation efficiency in a tunnel is effectively improved; the time for waiting for the tunnel ventilation quality to reach the standard in tunnel construction is greatly saved, the
