摘　　要：根据山不拉矿井现有通风系统选择通风阻力测定线路,采用气压计基点测定法测定各点通风参数,通过计算找出局部阻力较大位置,采用Fluent流体计算软件对局部阻力较大位置进行模拟分析,并结合矿井需风量计算找出优化方案:通过刷阔局部断面、改变局部通风线路来降低风阻,满足矿井通风需要。According to the existing ventilation system of the Shanbula mine,the ventilation resistance measuring line is selected,the ventilation parameters of each point are measured by the barometer base point measurement method,the position with larger local resistance is found out by calculation,the simulation analysis of the position with larger local resistance is carried out by fluent fluid calculation software,and the optimization scheme is found out by combining the calculation of the air demand of the mine:the local section is widened and the local ventilation is changed line to reduce the wind resistance,to meet the needs of mine ventilation.
