Abstract: In view of the current situation of the high concentration of toxic and harmful gases in the tunneling operation point
caused by insufficient ventilation during the difficult period of ventilation in Huipodi Coal Mine, this paper proposed a circulating
ventilation scheme. By adding an exhaust fan, circulating ventilation was realized. The actual application effect showed that the
gas volume fraction of tunneling operation point was significantly reduced, and the energy consumption was reduced. By applying
the circulating ventilation scheme, the mine saves 1 361 kW·h of electricity per day, and the economic benefits are good.

Key words: difficult period of ventilation; circulating ventilation; gas volume fraction; energy consumption
