矿井通风设计阶段主扇压力确定方法的研究

Research of the Method for Determining the Main Fan's Pressure at Mine Ventilation Design Stage

在分析研究最大阻力线路设计法和最小阻力线路设计法的优缺点的基础上 ,提出了中间阻力线路设计法 ,继而在综合这 3种方法的优点后 ,应用微分的观点提出了一种系统动态分析法。这种方法既考虑了井下生产条件的动态变化 ,又考虑到井下通风管理的难易。

Based on the analytical study of the strong and weak points of both maximum and minimum resistance line design methods,a midway resistance line design method is developed and a systematic dynamic analysis method is put forward from the viewpoint of differential and based on the combination of the advantages of the three methods.This analysis method considers both the dynamic change of underground mining conditions and the easyness of the underground ventilation management.
