With the increase of mining depth,many problems arise in the underground ventilation system under the interference of various factors.The corresponding solution measures can improve the quality of mine ventilation.Factors affecting ventilation system mainly include ventilation mode,ventilation network,ventilation power and ventilation facilities.By analyzing them,it can be seen that common problems include high frequency of facility failure,low ventilation efficiency,lack of ventilation supervision and backward management mode,etc.In view of these problems,solutions were proposed and the operation effect of ventilation system was discussed,in order to improve the stability and efficiency of mine ventilation system,and meet the needs of underground operation for fresh air flow.
