新区段通风系统形成过程中避免串联通风解决方案研究

Study on avoiding series ventilation solution during formation of new section ventilation system

济宁二号煤矿在11采区边角煤B11301工作面通风系统形成过程中,采用了全风压与局部通风相结合的混合式通风方法,避免了形成串联通风,取得了较好的效果,具有一定的推广价值。

In the formation process of the ventilation system of the B11301 working face of the side angle coal in the 11 mining area,Jining No.two coal mine adopts a mixed ventilation method combining all wind pressure and local ventilation,which avoids the formation of series ventilation.It has achieved good results and has a certain popularization value.
