摘要
煤矿瓦斯治理有多种方法,联合几种抽放方式(例如本煤层抽放、采空区抽放、高位钻孔抽放、专用瓦斯巷抽放等)综合治理效果好,可提高工作面煤层开采的安全性,并取得显著的效益。
There are several methods of mine gas prevention and control. The combined several methods of the mine gas drainage including seam gas drainage, gas drainage from goaf, high level borehole gas drainage and gas drainage with special gateway can have good results of comprehensive prevention and control which could improve the seam mining safety of the coal mining face with obvious benefits.
