摘 要:针对余吾煤业大断面煤巷支护困难的问题,以N3102工作面运输顺槽为工程背景,在加固拱理论的基础上,采用锚网索联合支护,形成较大范围的“双重组合加固拱”,结合现场地质情况,确定支护方案,选择合理的支护参数。实践表明:支护效果良好,达到了预期的支护目标,显著地提高了支护强度,能够满足矿井安全生产的需求,可为该矿其他类似巷道的支护提供借鉴。In view of the difficulty in support of large section coal roadway in Yuwu coal industry,taking the N3102 working face conveyor gateway as engineering background,based on the theory of strengthening arch,bolt-mesh-cable support is adopted,a large range of"double combination strengthening arch"is formed,support scheme is determined and reasonable supporting pa-rameters are selected in the paper,whose field practice shows that the support effect is good,which significantly improves the support strength,improves the roadway support effect,can meet the needs of safety production,and provides reference for other roadway support in themine.
