摘要
城山煤矿在不同区域、不同煤层和不同工作面,分别采取针对性的瓦斯抽采技术,实现了矿井瓦斯治理由"被动治到主动治"的根本转变。重点对顶板瓦斯巷抽采技术、高位钻场大直径近水平钻孔抽采技术、千米长钻孔抽采瓦斯技术、区段顶板瓦斯巷与采煤工作面上解放层联合抽采瓦斯技术、掘进工作面边掘边抽抽采技术进行了介绍。
Targeted gas drainage methods were used in different areas,different coal seam and different working face in Chengshan Coal Mine,which realized fundamental change from ＂passive cure＂ to ＂active control＂ on gas control in coal mine.Roof gas extraction technology,gas drainage technology by large-diameter drillholes in high-level drilling field,gas drainage technology using long drillholes over 1 000 meters,comprehensive gas drainage method in liberated seam over coal working face and gas roadway in section roof,driving while extracting gas on driving face method were introduced in the paper.
