| 摘 要： | 矿井主要通风机为2台4-72-11No16B离心式风机,风量小于实际所需风量,瓦斯超限。为满足矿井通风要求,经分析提出了3种改造方案。采用更换电动机提高转速增大风量的改造方案,并对通风网络适当改造,满足了矿井生产需要。

| Abstract: | The main ventilators in mine are two 4-72-11No16B centrifugal ventilators.That supplied air volume is less than necessary volume causes gas overrunning.Through an analysis,three updating measures are pointed out to meet the actual need.Comparing the all,coal mines adopted the second measure and updated ventilation nets appropriately to satisfy producing demand. |
