千秋煤矿主要通风机选型研究

Study on model selection of main fans in Qianqiu Colliery

针对千秋煤矿进入深部开采瓦斯涌出量增大,用风地点增多,通风能力不足的问题,对矿井通风系统进行了技术测定,分析了通风容易和困难时期的生产部署和配风情况,并提出通风系统优化改造方案,利用计算机对各个时期进行解网分析,最终确定矿井主要通风机的型号。该方案可大幅增加矿井供风量,保证矿井的安全生产。

In view of large amount of gas emission, increase in quantity of location where ventilation is required and lack in ventilation capacity, after appraising the ventilation system in the mine, the production arrangement and air distribution during good ventilation periods and bad ones are analyzed, and the optimization scheme of the ventilation system is proposed. Using computer to analyze the ventilation system at various periods, the model of main fans in mines is finally determined. The scheme can greatly increase the air supply in mines, so as to ensure the safe production in mines.
