通过对地面通风设施的优化,实现了通风机不停风倒换,杜绝了井下瓦斯超限,保证了矿井正常通风和生产安全;配合水平对空风门和立式置换风门,使得风机性能测试时不需拉离轨道,不需辅助设施,从而更加快速方便,准确可靠。现场实际表明,该系统安全可靠、功能完善,布置合理,值得推广。
Through the optimization of the ventilation system on the ground, the ventilator can be switched on continuously and the overrun of gas in the downhole can be avoided, and the normal ventilation and production safety of the mine can be ensured. With horizontal air-to-air and vertical air-replacement damper, Need to pull off the track, without auxiliary facilities, which is faster and more convenient, accurate and reliable. The actual field shows that the system is safe, functional, well-arranged, well-deserved promotion.
