摘　　要：通过对锯板坑钨矿通风系统现状调查,该矿存在高温季节主进风平硐风流反向等严重通风问题。通过建立矿井通风系统数学模型,确定了双主扇异地并联作业的两翼抽出式矿井通风系统,优化了主要通风井巷断面,合理分配了两翼通风线路的通风阻力,以及形成了独立、稳定的专用回风井巷。通风系统鉴定指标数据和现场作业环境的大大改善,都说明锯板坑钨矿通风系统能够给职工提供一个安全可靠的工作环境。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.
