By the mine ventilation investigation of the JuBanKeng tungsten mine, the airflow of the main intake shaft was reverse direction in the high temperature period. The exhausting ventilation system of two parallel fans installed at the different place was decided by establishing the mine ventilation model. The cross-sectional area optimization of the main shafts was performed for technology and economical reasons. The resistance of the two ventilation routes allocated rationally for the stability of the main fans. The separate upcast shafts were very important for the ventilation system. The appraisement index value of the ventilation system and the better working atmosphere showed the ventilation system of the JuBanKeng tungsten mine has provided a safe and reliable environment for the mine′s workforce.
