白羊岭矿为高瓦斯矿井,矿井瓦斯含量大,工作面绝对瓦斯涌出量为120.7 m3/min。为了有效地防治该矿瓦斯超限,特对掘进巷道采取了浅孔注水、深孔抽放的瓦斯治理方法。同时,通过对邻近层瓦斯抽采、生产工作面上隅角和采空区瓦斯进行治理,彻底地改变了该矿井瓦斯超限的现状。
The Archean Mine is a high-gas mine with a large gas content in the mine and an absolute gas emission of 120.7 m3 / min on the working face. In order to effectively control the mine gas overrun, especially for tunneling adopted shallow hole water injection, deep hole gas drainage management methods. At the same time, the status of methane overrun in the mine has been completely changed by harnessing the gas drainage in the adjacent layers, the upper corner of the working face and the gas in the goaf.
