阳煤三矿竖井15~#煤扩二区通风系统优化实践

Optimization Practice on Ventilation System at Kuoer Area, No.15 Coal Seam, No.3 Colliery, Yangquan Coal Mining Industry Group Co.

通过利用闲散巷道与回风巷并联通风,绕过了回风断面不足的局部地段,确保了扩二区风量充足,降低了主要通风机通风负压。

Due to exceeded ventilation negative pressure of main ventilator, roadway maintenance and whole lane measures are often taken at Kuer Area, No.15 Coal Seam, No.3 Colliery.But because of no transport system in return airway, problems of transporting materials difficulties and more labor are existing.Idle roadway and return airway parallel ventilation are used to pass the local sections of return section, which ensures sufficient air volume at Kuer Area and reduces ventilation negative pressure of main ventilator.
