摘　　要：针对铁新矿井因采掘延伸造成通风能力不足,现场进行了通风阻力测定,分析了通风系统存在的主要问题。根据分析结果和现场情况,提出了增补辅助回风巷和回风斜井、新建北风井、增补煤层辅助回风巷和反井钻孔3种改造优化方案。采用矿井通风三维动态模拟仿真系统对3种方案进行了模拟计算分析,选择出增补辅助回风巷和回风斜井为最优的改造方案。该优化改造方案应用后,解决了矿井通风能力不足的问题。Based on the ventilation deficiency of some mine,ventilation resistance was measured,problems of the ventilation system were analyzed,adding auxiliary return air roadway and air return shaft,northern air shaft,auxiliary air return roadway and countershaft drilling in coal seam were put forward,mine ventilation 3 d dynamic simulation system was applied to simulate the three plans,adding auxiliary return air roadway and air return shaft plan was adopted,the optimized plan solved the insufficient ventilation of the mine.
