林西矿通风系统改造优化设计

Linxi Coalmine Ventilation System Optimization Design

随着矿井向十二水平延深,矿井通风区域增加,通风路线越来越长,工作面需风量增大,且巷道失修比较严重,导致矿井通风阻力增大,负压较高。通过对林西矿通风系统现状分析,提出了矿井通风系统改造方案,经网络解算,通风系统改造后能满足矿井需风量和通风阻力的要求。

Along with extending to 12th level, mine ventilation area has increased, and ventilation route be-come longer and longer, working face needs to increase air volume, and roadway is in bad repair seriously, which resulted in increased resistance of mine ventilation, and negative pressure is higher. Through the a-nalysis about the present situation of Linxi Coalmine ventilation system, this paper puts forward the mine ventilation system transformation scheme. By network calculation, after reforming ventilation system, it can satisfy the requirement of mine air volume and ventilation resistance.
