摘要
介绍了某高瓦斯煤矿主采煤层工作面走向高抽巷抽采卸压瓦斯的瓦斯治理技术模式。采用理论分析与实际观测等方法,分析确定了顶板走向高抽巷的合理布置参数,高抽巷的合理层位在57～60 m。现场实践表明,该工作面瓦斯抽采治理技术模式适合矿井实际条件,保证了工作面安全回采。
This paper gave a description of the control technology mode of relieved-gas drainage by high-level entry along the strike of the working face in a high-gassy mine. It analyzed and determined the rational arrangement parameter of the high-level entry along roof strike by theoretical analysis and actual observation, and the rational position of the high-level entry should be 57 to 60m. The practice showed that this control technology mode for gas drainage from the working face is suitable for the actual condition of the mine and can ensure the safe mining of the face.
