优化盘区通风系统并联回风降低通风阻力探讨

为满足忻州窑矿东三盘区14-3#层采掘工作面用风需求,决定对东三盘区通风系统进行优化改造,通过改造112#层轨道巷和112#回风巷并联回风,将串联巷道改造为并联风道.经理论计算,采用并联风网之后通风阻力降低了954 Pa,提高了东三风井主要通风机运行稳定性,提升了矿井的通风能力.

Discussion on Optimizing Parallel Return Air of Disk Ventilation System to Reduce Ventilation Resistance

In order to meet the air demand of 14^-3#level mining face in east panel 3 of Xinzhouyao Mine,it is decided to optimize and transform the ventilation system of east panel 3.Through the transformation of 11^-2#layer track roadway and 11^-2#return air roadway,the series roadway is transformed into parallel air tunnel.According to the theoretical calculation,the ventilation resistance is reduced by 954 Pa after the parallel ventilation network is adopted,the operation stability of the main fans in east 3 air shaft is improved,and the ventilation capacity of the mine is improved.
