Abstract: The mine air regulation is an important content of ventilation and safety management，the mine air volume adjustment methods is reviewed，taking the mine of DaShuCun as the research object，and taking the mining area as regional branches，the equivalent and simplification graph of the mine ventilation network is drawn，when the regional branches increased resistance，the correlation of each mining area air volume and total air volume with the wind resistance change in the region increased resistance branch，their amount and ratio relations were studied. The results showed that: each mining area air volume and total air volume is closely related to the wind resistance change in the region increased resistance branch，the increase resistance mining area with mines and other mining area air volume variation meet the amount plus relationships. Compared to the local branch increased resistance adjustment，this method can grasp the change of the total air volume of the whole mine mining area，and it is more helpful for mine airflow of macro regulation.
