Abstract In order to grasp the matching state of power and resistance of the ventilation system in Gucheng Coal Mine and judge the stability of the ventilation system, the stability of the airflow in the ' H ' type ventilation system of Gucheng Coal Mine under the joint operation of multiple fans is analyzed by taking the parallel operation working point of the ventilation power facilities in Gucheng Coal Mine as the starting point, and the discriminant of mutual interference in the parallel operation mode of multiple air shafts is obtained. Based on this, the interference discriminant prediction analysis of the double ' H ' type ventilation system formed after the operation of Baodian air shaft in Gucheng Coal Mine is put into operation, and the intelligent prediction simulation is carried out by using the ventilation management information system of Gucheng Coal Mine. It is concluded that the combined operation of mine fan will not produce mutual interference.
