南井通风系统改造优化设计

The Optimization Design of Nanjing Mine Ventilation System Transformation

针对矿井通风区域增加、通风富裕系数不足、通风路线加长、通风阻力增大的问题,通过对南井通风系统现状进行综合分析,提出了3个矿井通风系统改造方案。经过方案比较,选取在主井老风机东北侧安装主要通风机的方案。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,实现了通风系统稳定、安全可靠的目标。

Based on increasingly ventilation area, insufficient ventilation coefficient, ventihtion route extension, ventilation resistance increase problem, through the comprehensive analysis of ventilation system in Nanjing Mine, 3 transformation scheme of mine ventilation system was put forward. Through the comparison, the main fat machine was set in the northeast of main shaft. By internet calculation, the ventilation system after transformation met the needs of mine air quantity and air resistance, which realized the stable and reliable ventilation system.
