平煤二矿新风机挂网前后系统优化改造

Optimization Transformation for New Fan System Before and After Hanging in Pingdingshan Coal Group No.2 Coal Mine

为确保平煤二矿三水平回风井挂网前后通风困难时期各用风地点风量充足、通风系统稳定及主要通风机合理、稳定的运转,对矿井通风系统进行技术测定,提出了矿井通风系统优化改造方案。利用计算机对各个方案进行解网分析后。

To ensure that the enough air used by different site,ventilation system stable and main fan reasonable and stable operation during difficult period before and after hanging in the three level return air wells,for mine ventilation system technological measurement,the paper put forward mine ventilation system optimization and transformation schemes.Using the computer solution nets analysis for each plan,the paper finally determined ventilation system optimization reconstruction scheme before and after three level fan hang nets.
