| 摘 要： | 目前在我国现有矿井总量中,高瓦斯矿井占到了20%以上,在高瓦斯矿井中,由于煤层中瓦斯含量较高,巷道开拓过程中,瓦斯涌出量多,会造成空气中瓦斯超标、超限,严重阻碍了开拓工作的正常进行。通过巷道开拓的实例,阐述了瓦斯抽放对巷道开拓的有益作用。

| Abstract: | At present,high-gas coal mine accounted for more than 20% in the total volume of our existing mines.Since the high content of coal seam gas,in the process of exploit tunnel,multi-gas emission will cause excessive gas in the air,overrun,a serious impediment to pioneering work carried out normally.Through the tunnel exploit,the example of gas drainage of the roadway described the beneficial effects of exploit. |
