摘要
以王家岭矿18101工作面开采为实例,分析了大断面回采煤巷高帮破坏机理以及顶板锚杆锚索协同支护机理,提出大断面巷道高帮强化支护方式,应用大埋深大断面煤巷的协同优化控制支护技术;通过FLAC3D模拟软件分析,确定了优化合理的联合支护方案。实践表明,联合支护应用效果良好。
By analysis of top side failure mechanism at large section mining roadway and roof anchor-cable cooperative support mechanism, the author presents the reinforced top side support method at large-section roadway with the optimized combined support scheme by FLAC3Dsimulation software analysis, which has been proved effective.
