摘　　要：针对邢东矿千米深井煤巷底板大变形的控制难题,在总结深井煤巷变形机制及支护机理的基础上,分析-980m水平第一联络巷底板变形失稳的主要原因,并结合现场地质生产条件,提出顶帮"锚网梁索"和底板"U型钢反底拱+底板锚杆+混凝土回填"的联合控制技术,并现场应用。现场实践表明,采用该方案45d后巷道变形趋于平稳,顶板最大下沉量47mm,两帮移近量98mm,底鼓量32mm,解决了-980m水平第一联络巷强烈底鼓的围岩控制难题,并为类似巷道围岩控制提供了技术支撑。In order to solve the floor large-deformation difficult problem of coal roadway in 1000m deep mine of Xingdong Colliery, this paper analyzed main reason of floor deformation and failure of 1 ~＇ Connection Roadway and put forward combined control technology in- cluding anchored cable, beam and mesh for roof, U-style steel inverse arch ＋ floor anchored bolt ＋ concrete stowing for floor. This tech- nology was applied in application. Practice showed that roadway deformation was stable, maximum roof subsidence was 47mm, two-side convergence was 98mm and floor heave was 32mm, which solved the control problem of strong floor heave and provided technical sup- porting for similar roadway.
