矿井通风系统优化研究与应用

Research and Application of Mine Ventilation System Optimization

针对通风系统复杂、阻力大的资源整合的店上矿井,结合该矿井通风现状及通风系统存在的问题,通过方案比较,对矿井通风系统进行了优化降阻改造。结果表明:1号风井主要通风机负压可由3 150 Pa降到2 837 Pa,2号风井主要通风机负压可降到2 905.1 Pa,1号风井、2号风井风量可分别增加512 m3/min、300m3/min,通风系统更为合理。

Aiming at the integration of resources with complex ventilation system and high resistance,combined with the present situation of mine ventilation and the existing problems of ventilation system,the mine ventilation system is optimized and reformed through scheme comparison.The results show that the negative pressure of the main ventilator in No.1 air shaft can be reduced from 3 150 Pa to 2 837 Pa,2#,and the negative pressure of the main fan can be reduced to 2 905.1 Pa,1.The air volume of No.2 air well can be increased by 512 m3 min,300 m3 min,and the ventilation system is more reasonable.
