摘要
针对平煤股份六矿丁5-6-21110工作面,将顺层预抽钻孔预抽回采区域煤层瓦斯理论引入煤巷掘进工作面,通过在风巷施工顺层钻孔,掩护中间巷的掘进。在该工作面按照递进掩护的思路,形成一套完备的区域及局部瓦斯治理技术,分析中间巷掘进期间瓦斯涌出量以及效果检验值的变化情况,验证了顺层递进掩护钻孔的保护效果。
For the D5-6-21110 face of Pingdingshan coal mining shares six mine,preliminary drainage hole along coal seam mining area coal seam gas theory is introduced coal roadway drivag,through drilling holes in the wind tunnel construction bedding,covering the middle lane heading. Cover of the coal face according to the progressive thinking,forming a comprehensive gas control technique in regional and local. Analysis of roadway gas emission verification values during changes,verify CIS drilled cover layers of protection.
