摘　　要：针对余吾矿复杂通风系统存在的风流不稳、风量供应紧张、通风阻力过大的困境,利用Ventsim软件对通风系统进行风网解算,结合生产实际,分析找出现有通风系统存在的不足,并提出优化改造方案。经模拟分析和实践检验,优化改造后的通风系统各项指标得到明显改善,通风系统稳定运行,确保了矿井的安全生产。Aiming at the problems of complex ventilation system existing in Yuwu Mine,such as air flow instability,air supply shortage,too large ventilation resistance etc,the ventilation system of mine were calculated by Ventsim software.In combination with production practice,the shortcomings of the existing ventilation system were analyzed and the optimization scheme was put forward.Through simulation analysis and practice test,all indexes of ventilation system after improvement were obviously improved,and the stable operation of ventilation system ensured the safe production of mine.
