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.

摘要

矿井通风智能化是通风系统发展的必然趋势。快速、精确、按需（RPOD）调节风量是矿井智能通风需要解决的主要问题之一。为实现风量的RPOD调节，阐述了目标支路、主动支路和被动支路的概念，并提出了一种算法。然后根据灵敏度理论对活动支路进行排序，利用灵敏度衰减率理论和最小风量原理计算活动支路的调节范围。最后根据被动支路的总风量确定具体的主动支路和调节范围。并结合山西省武阳煤矿实际通风情况对该理论进行了验证。研究结果将为矿井智能通风RPOD调节提供理论指导。
