| This paper relates to the Shaqu coal mine adopts Multiple shaft draft type,The ventilation system is more and more used in mineproduction,Of course, when running this ventilation may occur mutual interference phenomenon,Resulting in unstable airflow ventilation,Some local places mine ventilation even reversed.Based on the research of mine ventilation system stability mechanism,This paper has been got a detailed analysis of the method of distinguishing the two mutual interference of diagonal and two into ventilation system and other factors that influence the multi-shaft ventilation stability.About the mineventilation system optimization on the analysis.This paper established the weight of fuzzy comprehensive evaluation method and index to evaluate the determination method of mine,before the system optimization of Shaqu coal mine,Firstly,we investigate the Shaqu mine ventilation resistance determination of current status and acquire the network basic data table of the mine,Using the optimization of ventilation system and analysis software for calculation of mine ventilation system and using stability analysis of interference and determination method before analyse the present situation in the mine ventilation. Summarizing several optimization scheme of ventilation system in Shaqu mine, Finally, this paper get some resonable schemes by using fuzzy comprehensive evaluation method, the rest of the scheme is the best ventilation system reform scheme. |
