摘要
以13031运输巷道为工程背景,调研了厚煤层大断面巷道围岩变形特征,分析得出大断面巷道的破坏机理以及影响巷道稳定的因素,提出锚网索联合支护的具体实施方案。现场实践表明,厚煤层大断面碎裂顶板应用锚网索联合支护的设计安全合理,可以有效控制围岩变形,现场试验效果良好。
Taking the 13031 transport roadway of as engineering background,the characteristics of surrounding rock deformation of large section roadway in thick coal seam are investigated,the failure mechanism and factors affecting roadway stability are analyzed,and finally the concrete implementation scheme of bolt-net-cable combined support is put forward.The field practice shows that the design of combined bolting,netting and cable support for large section broken roof in thick coal seam is safe and reasonable,which can effectively control the deformation of surrounding rock,and the field test effect is good.
