Airway Sensitivity Recognition and Its Effect on Ventilation System Airflow Stability

摘要：

Diagonal connection structure recognition and fuzzy evaluation have usually been used in analysing mine ventilation system airflow stability. However, complicated diagonal connection structures choice and difficult airflow direction identification will appear in diagonal connection structures recognition method. And it is also difficult to assign network branch stability weight during fuzzy evaluation. Multiple regression analysis has been adopted, and the optimum regression equation about the air quantity and ventilation resistance has been deduced. According to airway sensitivity, the ventilation system airflow stability has been known. The calculated results are consistent with the practical situation. Research shows that the sensitivity of airway is independent of airflow resistance, and it is close to mine ventilation system stability.
