淮北矿业集团芦岭矿为高瓦斯突出矿井，采用传统的底板双岩巷穿层钻孔抽采开采区域瓦斯，底板岩巷工程量大，维护困难。为提高生产效率，减少巷道工程量，对Ⅱ84采区进行优化设计。底板双岩巷采用高低巷布置，能够提高打钻效率，减少维护工程量，技术经济效益显著，彻底改变了芦岭固有的巷道布置模式。
淮北礦業集糰蘆嶺礦為高瓦斯突齣礦井，採用傳統的底闆雙巖巷穿層鑽孔抽採開採區域瓦斯，底闆巖巷工程量大，維護睏難。為提高生產效率，減少巷道工程量，對Ⅱ84採區進行優化設計。底闆雙巖巷採用高低巷佈置，能夠提高打鑽效率，減少維護工程量，技術經濟效益顯著，徹底改變瞭蘆嶺固有的巷道佈置模式。

As of high gas prominence, the conventional drilling through strata technology is adopted for gas exploitation at the floor dual rock roadway of Lu Ling Coal Mine, Huai Bei Coal Mining Group, leading to massive construction work at the floor rock roadway and difficul- ties in maintenance. To enhance the production efficiency and reduce the roadway construction work, optimization design is carried out for Ⅱ 84 mining zones. The adopted high and low roadway layout for the floor dual rock roadway could contribute to enhanced drilling efficiency, lessened maintenance amount, as well as significant technical and economic benefits and completely changed roadway layout mode intrinsic to Lu Ling Coal Mine.
