摘　　要：针对安山煤矿中央并列式通风系统在开采后期出现通风阻力大的问题,分析了煤矿不同类型通风系统的优缺点,运用网络解算研究了通风系统优化方案。指出开采3盘区5-1煤时,通风阻力将会超限,通风路线过长和采区风量集中是通风阻力增加的原因。针对该问题提出了通风系统优化方案,通过新建大墩沟进、回风斜井等措施,将通风系统由中央并列式改造为中央分列式,经网络解算得到,优化后矿井在开采3盘区5-1煤时的最大阻力为1602.5 Pa,保证了矿井的后续开采,并提升了矿井通风系统的抗灾能力。In view of the problem of the central parallel ventilation system in Anshan coal mine in the later stage of mining,the advantages and disadvantages of different types of ventilation systems in coal mine are analyzed,and the optimization scheme of ventilation system is studied by network calculation.It is pointed out that when mining the coal in the 3 area 5-1,the ventilation resistance will exceed the limit,and the long ventilation route and the concentration of air volume in the mining area are the reasons for the increase of ventilation resistance.The ventilation system optimization scheme for the problem,through the new big pier ditch,return air inclined shaft,the ventilation system by the central parallel type for the central system,the network solution,optimization of the mine in mining 3 area 5-1 coal maximum resistance is 1602.5 Pa,ensure the subsequent mining of the mine,and improve the disaster resistance of the mine ventilation system.
