Abstract: Based on the energy equation of underground roadway's heat exchange in metal mine,the basic law of underground tunnel's heat exchange is analyzed,as well as the theoretical basis of the mine ventilation and pre-cooling. The practice in Dongguashan Copper Mine approved that the inlet air warm control in roadway improved the roadway's heat exchange efficiency to realize cooling.

Key words: Mine ventilation, Roadway, Heat exchange, Precooling, Exchange efficiency
