摘要
针对正令煤业胶带大巷穿层掘进巷道围岩变形的问题,结合胶带大巷掘进特点对巷道破坏原因进行分析。为了使胶带大巷在服务年限内达到稳定可靠的支护效果,决定采用全断面抗剪锚管索(ACC)方案+喷浆联合支护。实践表明,支护效果良好,达到了预期支护目的,为该矿其他巷道支护提供了借鉴。
In view of the problem of controlling the surrounding rock deformation of the roadway in the coal roadway of the coal industry,the causes of the roadway damage were analyzed in combination with the characteristics of the roadway tunneling.In order to achieve a stable and reliable support effect in the service area of the tape,it was decided to adopt the full-section shear anchor pipe(ACC)scheme+shotcrete joint support.Practice showed that the support effect was good and achieved the intended support,which provided reference for other mines'roadway support.
