【正文】 up the mountain back to the wind, coal face using Utype upstream ventilation, the use of heading face pressurein ventilation, mine design to be easy to time the wind was 139 m3 / s, designed to be a difficult time for the air flow 146m3 / s. Elected to the main mine fan model BD NO22, the motor model YB35M28, and the structure of the mine ventilation required to set up their equipment. Key words ： ventilation design mine ventilation system ventilation resistance III 目 錄 摘 要 ......................................................................................................
