To solve the problem associated with the assessment on the stability of ventilation system in Honglin mine,this study investigates the problem using sensitivity theory.Based on quantitative analysis method,the ventilation system stability is analyzed to provide criteria for maintaining the stability of a branch and whole ventilation network.In the study,the affecting degree curves of branch affecting on the system and the affected degree curves of branch affected by the system are obtained through numerical simulation.The study results show that the degree of a branch affecting on whole ventilation system can be seen in the affecting degree curve while the degree of other branches affecting on the current branch can be seen from the affected degree curve.The stability analysis on a ventilation system based on sensitivity provides a valuable reference to the safety management of the ventilation system in Honglin mine.
