摘要

Through the usage of simulation software based on the network layout, airwayresistances and parameters of main fans, ventilation calculations were performed to ana-lyse the current situation as a ventilation wall built in No.1 west airway to separate the twosubsystems. A comparison of simulation results and in-site measurements show that themaximum deviation is less than 10%. Further calculations for the case that the ventilationwall in No.1 west airway is removed to consider the consequences when the two sub-systems are merged together. Results of the simulation show that the total airflow rate in-creases, and the ventilation resistance of the mine decreases in comparing with that of theforegoing simulation.
