摘　　要：为解决采空区下大断面开切眼在掘进过程中的巷道围岩变形量大影响安全施工等问题,针对任楼煤矿Ⅱ8_(2)24N工作面切眼的工程概况,提出了导硐刷帮、交替掘进一次成巷的施工方案,并设计了锚带网索联合支护方案及其支护参数。现场矿压监测数据验证了该掘进施工工艺和支护方法的合理性,为同类大断面切眼的施工工艺及围岩稳定性控制提供参考。In order to solve the problem that the surrounding rock deformation of the roadway affects the safe construction in the process of excavation,aiming at the general situation of the cutting project of the Ⅱ8_(2)24N working face in Renlou Coal Mine,the construction scheme of guide adit tunnel brushing and alternate driving is put forward,and the combined support scheme of anchor belt,mesh and cable and its supporting parameters are designed.The on-site mine pressure monitoring data verify the rationality of the tunneling construction technology and support method,which provides a reference for the construction technology of similar large cross-section cutting and the stability control of surrounding rock.
