Abstract：For solving the difficult problems of the ventilation of complicated tunnel and great variety face drilling and blasting method，a combined ventilation system is designed，based on the developing on the low pressure，great flow capacity and saving-power fan. The blow method is used in main tunnel and the mixed ventilation with lanewav-ventilation is employed in the side tunnel after the main sap is accomplished.
