摘　　要：孔庄煤矿原G4-73-11№25D型离心式风机服务年限长,性能老化,通风富余能力不足,不能满足矿井改扩建后供风要求。现根据矿井改扩建后所需通风能力,设计采用FBCDZ-8-№26型对旋轴流式通风机,新风机通风能力强,反风操作方便。新建通风设施预先安装施工完毕,新老风机切换时只需用钢风筒将新老风道对接即可。The original G4-73-11 №25 D centrifugal fan in Kongzhuang Coal Mine has long service life, aging performance and insufficient ventilation and surplus capacity, which can not meet the requirement of ventilation after the mine expansion. According to the ventilation capacity of the mine after the expansion, the design of FBCDZ-8-№26 type rotary axial fan was adopted. The ventilation ability of the new fan is strong and the anti wind operation is convenient. The new ventilation facilities are pre installed and completed. When the old and new fans are switched, the workers only need to connect the old and new air ducts with steel air ducts.
