Ventilation system is one of the main factors affecting mine safety production.The quality of ventilation directly determines whether the air quality and working environment of the working face can meet safety regulations.In order to address issues such as insufficient fan power and air leakage in the ventilation system of the Dabaiyang Gold Mine,the Ventsim ventilation simulation software is used to establish a three-dimensional model of the ventilation system.Starting from the ventilation volume adjustment required for mine production,network calculation and dynamic simulation are carried out on the optimized zone ventilation scheme with balanced return air from the east and west shafts.The ventilation network and fan selection are optimized,successfully resolving the issue of insufficient effective ventilation volume in the mine ventilation system.This is of significant importance for improving the economic efficiency of the mine.
