摘　　要：针对23采区管子道临近下白峪超大断层(H=200~1000 m),导致该区域附近的岩层较破碎,同时该巷道又位于井下深部区域,受地应力的影响,巷道容易变形,且又是以+30°大坡度施工,如何解决在复杂地质条件下深部巷道大坡度施工支护问题,先在工作面搭设一个施工平台,采取防片帮、冒顶措施以及采用"高强锚杆+注浆锚杆+注浆锚索+钢筋网+喷射混凝土"联合支护,来解决大坡度施工支护问题。该项目的成功应用将为其他矿井邻近大落差断层布置深部巷道提供参考依据,同时该项目主要采用联合支护来治理巷道变形问题,可为制定邻近大落差断层布置深部巷道支护技术标准提供参考价值。In the light of Twenty-three the pipe road in the mining area is close to Xiabaiyu super large fault(H=200~1000 m)at the same time,the roadway is located in the deep area of the mine.Affected by the earth stress,the roadway is easy to deform+30°How to solve the problem of large slope construction and support in deep roadway under complex geological conditions.First,set up a working face for the construction platform,the measures of preventing sheet wall and roof falling and the combined support of"high strength bolt+grouting bolt+grouting anchor cable+steel mesh+shotcrete"are adopted to solve the problem of large slope construction support.The successful application of the project will provide a reference basis for other mines to arrange deep roadway adjacent to large drop fault.At the same time,the project mainly adopts combined support to control the deformation of roadway,which can provide a reference value for formulating technical standards for supporting deep roadway adjacent to large drop fault.
