西铭矿42204综采工作面瓦斯抽采技术应用

Application of Gas Drainage Technology at 42204 Fully-mechanized Mining Face of Ximing Colliery

本文以西铭煤矿42204工作面地质条件为基础,为有效治理工作面瓦斯,提出了采用本煤层预抽、顶板走向钻孔、走向高位长钻孔以及采空区埋管的方法治理工作面的瓦斯。分析工作面瓦斯抽采效果表明,综合瓦斯抽采方法起到了较好的治理效果,能够保证工作面的安全生产。

Based on the geological conditions of the 42204 working face in Ximing Colliery,the author proposes the gas control measures of pre-drainage in coal seam,borehole along roof,high-position strike long borehole and buried-pipe at goaf,which can effectively control the gas and ensure the safety of production at the working face.
