小峪煤矿并联回风降阻方案的实践与应用

Program practice and application of parallel return air to reduce resistance in Xiaoyu Coal Mine

本文针对老矿井通风路线长,回风断面小风阻大的难题,提出了建立并联回路来形成降阻的方案,通过数据分析对比,确定方案并实施,保证了矿井安全生产。

For the problems of the long ventilation route, the small return air section and big wind resistance of the old mine, the program of establishing the parallel circuit to reduce the resistance is proposed, through the data analysis and comparison, the program is determined and implemented, it ensures the mine safety production.
