随着矿井向深部开采,压风管路越来越长,管路的阻力损失及漏风致使风压不足的问题愈加严重,同时,压缩空气送到井下用风点,由于温度降低引起风压降低的能量损失也是不容忽视的问题。我们在松藻煤矿一井水平延深设计时,采用了在井下边界采区使用无基础空压机就近供风方案,比采用井上集中供风的效果好。 With the mining to the deep mine, the compressed air pipelines are getting longer and longer, the resistance loss of the pipelines and the problem of insufficient wind pressure caused by air leakage become more and more serious. At the same time, the compressed air is delivered to the downhole windward point and the wind pressure is reduced due to the temperature decrease The energy loss is also a problem that can not be ignored. When we designed the depth of a well in Songzao Coal Mine, we adopted the near-side air supply scheme without base air compressor in the underground boundary mining area, which is better than the centralized air supply in the well.
