摘要
为进一步提高工作面通风安全性,消除上隅角瓦斯积聚隐患,提高工作面煤柱回采量,漳村煤矿通过技术研究,针对2603工作面提出了沿空留巷Y型通风系统的应用。分析了Y型通风系统的原理及优点,探讨了沿空留巷Y型通风系统的实际应用。实际应用效果表明,沿空留巷Y型通风系统的应用解决了上隅角瓦斯积聚问题,减少了巷道掘进工程量,提高了煤柱回采量,取得了显著的应用成效。
In order to further improve the ventilation safety of the working face,eliminate the hidden danger of gas accumulation in the upper corner,and increase the coal pillar recovery rate of the working face,Zhangcun Coal Mine proposed the application of Y-type ventilation system in gob side entry retaining for the 2603 working face through technical research.This paper analyzed the principle and advantages of the Y-type ventilation system,and discussed the practical application of the Y-type ventilation system in gob side entry retaining.The actual application results show that the application of the Y-type ventilation system in gob side entry retaining has solved the problem of gas accumulation in the upper corner,reduced the amount of roadway excavation works,increased the amount of coal pillar extraction and achieved significant application results.
