Study on the Sensitivity in Mine Ventilation Network System

The sensitivity of underground complex ventilation network is studied according to the change relationship between air resistance and wind in the ventilation system and with the local ventilation map of Xiangshan Mine as the example.The sensitive regions can be gotten in the form of graphics,then the ventilation in these sensitive areas can be mainly changed.With this,not only the working hours or materials can be reduced when we build,change or expand mines,but also the safety management in underground ventilation system can be enhanced.
