The air leaks and the main fan malfunctions in the ventilation system of Wanjiawu Mining Area,Jinshan Gold Mine,Jiangxi.In view of that,the paper proposed the technical optimization plan of sectioned ventilation system in ventilation section,established underground 3D ventilation model with Ventsim 3D ventilation numerical simulation software and the ventilation simulation and ventilation network calculation.The simulation results show that the sectioned ventilation system in ventilation section has good ventilation performance,can improve underground air quality,is able to avoid the safety risks caused by poor visibility,ensures the working environment for underground staff and can provide theoretical basiss for the renovation of ventilation system in Jinshan Gold Mine,Jiangxi.
