摘　　要：随着地下矿山生产规模以及开采深度加大,矿井通风系统的合理可靠性面临重大挑战,并成为了井下安全高效生产的决定性因素之一。本文提出了复杂深埋矿山通风系统优化的策略与流程,并采用现场调查和数值模拟相结合的方式开展了湖南水口山康家湾矿通风系统优化研究。通过通风系统测定、风流线路优化、通风工程改造、风机选型等流程为康家湾矿提出了通风系统优化方案。最后,建立了康家湾矿三维通风系统模型,并通过数值模拟评估了该矿通风系统优化效果。研究结果表明,依据本研究的通风优化方案,康家湾矿新鲜风流全部转入预定深部中段,通风系统整体效率由68.2%提升至80.5%,污风串联和风流短路问题得到解决。本研究有助于为深部复杂矿井通风系统优化提供科学指导,为保障地下金属矿山安全生产提供了关键技术支持。With the improvement of the production scale of underground mines and the depth of mining,the reasonable and reliability of the mine ventilation system faces major challenges and has become one of the decisive factor in safe and efficient production.This study proposes strategies and processes for optimizing complex deep-mining ventilation systems.A combination of field investigation and numerical simulation was adopted to conduct optimization research on the ventilation system of Kangjiawan Mine in Shuikoushan,Hunan.The processes such as ventilation system measurement,Ventilation line optimization,ventilation engineering transformation,and fan selection have proposed a ventilation system optimization plan for Kangjiawan Mine.Finally,the three-dimensional ventilation system model of Kangjiawan Mine was established,and the optimization effect of the ore ventilation system was evaluated through numerical simulation.The results show that according to the ventilation optimization scheme of this study,the airflow of Kangjiawan Mine is transferred to the deep stage according to the schedule.The overall efficiency of the ventilation system has been promoted from 68.2%to 80.5%and the problems of polluted air serialization and airflow short circuits were resolved.This study helps provides scientific guidance for the optimization of complex mine ventilation systems and provides crucial technical support for ensuring safe production in underground metal mines.
