摘要
针对低透气性难抽单一煤层的煤与瓦斯突出矿井,通过沿采空区水平卸压带掘进巷道防止煤与瓦斯突出,实现快速掘进,保证了巷道安全和工作面正常生产,实现了高产高效,降低了瓦斯治理的成本。
Aiming to coal and gas outburst coal mine which is low permeability and difficult to drain gas ,coal and gas outburst is eliminated by draining goaf roadway in Hongyuan coal mine ,this technique prevented coal and gas outburst and increased the tun‐neling speed and realize high efficient and low price of gas governance cost .
