祁南矿中央风井通风系统优化改造的实践

PRACTICE AND COGNITION OF OPTIMIZING AND REBUILDING VENTILATION SYSTEM OF CENTER VENTILATION SHAFT IN THE QINAN MINE

摘要: 祁南矿中央风井所服务的矿井西翼和北翼系统通风阻力不均衡,北翼通风线路较长,通风阻力大,风量不能满足生产需要。对该系统进行优化改造后,北翼通风阻力出现大幅度下降,风量得以提升,满足了安全生产的需要,并获得了较好的技术经济效益。

Abstract: The ventilation resistance of the west side and the north side serviced by the enter ventilation shaft is not a equilibrium condition in the Qinan Mine.On the north side,the ventilation pate is long and the ventilation resistance is strong and the wind capacity doesn't meet the yielding demand.After the ventilation system is optimized and rebuilt,the ventilation resistance of the north side descends to great extent and the wind capacity of the side ascends,which meets the yielding demand and makes the Qinan mine attain a better benefit.
