The invention relates to the technical field of mine safety, and discloses an optimization and adjustment method for a mine ventilation system. The method comprises the steps that ventilation parameters of all roadways of a mine are obtained, and a mine ventilation network mathematical model is constructed; inputting the air volume of the roadway where the ventilation facility is located into the mine ventilation network mathematical model, and resolving to obtain the adjusted air volume of the target roadway; judging whether the adjusted air volume of the target roadway is smaller than that of the target roadway; if yes, adjusting the air volume of the roadway where the ventilation facility is located; otherwise, outputting the wind resistance value of the roadway where the ventilation facility is located; and calculating the adjustment value of the ventilation facility according to the wind resistance value of the roadway where the ventilation facility is located and the initial wind resistance value of the
