Abstract: In order to further improve the reliability of the ventilation system of multi-sections stoping mine, reduce the dirty air circulation and the external air leakage of mined-our area and improve the mutual restriction effect of the return air of multi-sections, the extraction ventilation pattern of the combination of main fan and auxiliary fan is proposed, based on the return air pressure balance and air volume balance principle of series and parallel of multi-stations and multi-fans, and the fan frequency conversion control technique, the air volume matching of the return air of series and parallel of multi-stations and multi-fans is realized, about 29.22 m3/s air leakage of the mined-out area and 20.68 m3/s dirty air circulation are reduced, the effectively air volume rate is increased more than 10%,the underground environment quality is improved effectively, the social and economic benefits are obvious.
