摘　　要：晋华宫矿中央风井主通风机担负区域通风路线长,巷道通风阻力大,部分巷道风速超限、主通风机运行负荷大。通过对中央风井主通风机升级改造,对部分巷道断面刷大的技术方案,降低了区域通风阻力,满足了新增采掘队组、盘区产量进一步提升的要求,保障了矿井安全生产。Aiming at the problems of long ventilation route,large ventilation resistance,air velocity overrun and high operation load in the responsible area of main ventilator in central air shaft,the author proposes upgrading the main ventilator and expanding the section in partial roadways,which can reduce the zonal ventilation resistance,satisfy the requirements of additional mining team and increasing area yield,and guarantee the safety production.
