西庞井通风系统优化改造实践

Optimization practice for Xipang well ventilation system

为了满足矿井通风要求,保证矿井正常接替,针对当前风量不足的问题,东庞矿西庞井提出对矿井进行通风系统改造,形成两进一出的中央边界式通风格局,增加1个供风通道,减少回风距离,降低了通风阻力,通风阻力下降到1053 Pa,通风能力上升到4129m^(3)/min,确保了扩延区以及后期深部开采的用风量。

In order to meet the requirements of mine ventilation and ensure the normal replacement of the mine,in view of the current problem of insufficient air volume,Xipang well of Dongpang Mine proposed to transform the ventilation system of the mine,forming a central boundary ventilation pattern with two inlets and one outlet,increasing one air supply channel,reducing the return air distance and reducing the ventilation resistance.The ventilation resistance decreased to 1053 Pa,and the ventilation capacity increased to 4129 m^(3)/min,which ensured the air volume of the extended area and the later deep mining.
