Abstract
Abstract The intelligentization of mine ventilation is the inevitable development trend of ventilation system. Rapid, precise, and on-demand (RPOD) adjustment of air volume is one of the main problems that need to be solved in mine intelligent ventilation. In order to realize RPOD adjustment of air volume, the concepts of target branch, active branch and passive branch were elaborated and an algorithm was proposed. Then active branches were sorted based on the sensitivity theory, and the adjustment range of the active branches were calculated using the sensitivity attenuation rate theory and the minimum air volume principle. Finally, the specific active branch and adjustment range were determined according to the total air volume that the passive branch. The theory was verified based on the actual ventilation situation of Wuyang Coal Mine in Shanxi Province. The research results will provide theoretical guidance for the RPOD adjustment for mine intelligent ventilation.
