金川矿山长距离巷道掘进通风技术研究与应用

金川矿区随着深部开拓及周边贫矿的开采, 斜坡道等长距离独头巷道掘进较多,新鲜风流得不到保障,作业面风量、风速达不到现场施工需求,为了获得良好的通风效果,在改善局扇性能,优化风筒结构、风机串联, 以及采取钻孔通风方式等方面做了大量尝试和研究,确保了长距离独头巷道掘进作业面风量、风速的基本需求,取得到较好的通风效果。

Research and Application of Jinchuan Mine Long Distance Roadway Excavation Ventilation Technology

Jinchuan Mining With deep exploration and the surrounding low grade ore mining, ramps and other long single entry boring more fresh air flow can not be guaranteed, work surface wind, wind speed to reach the on-site construction needs,in order to get a good ventilation effectdone a lot of attempts and research to improve the performanc of the local fan, optimize the structure of hairdryer, fan series, and take the way of drilling ventilation to ensure a long single entry excavation work surface wind, wind speed, basic needs, to obtain a more A good ventilation.
