| 摘 要： | 针对五里堠煤矿2101胶带顺槽掘进期间受X4陷落柱残余应力影响,巷道掘进至450～510 m段巷道顶板出现破碎、下沉,通过分析钢棚、锚杆(索)支护在应对破碎区支护过程中存在的不足,提出了“注浆+锚棚”联合支护技术,采取联合支护技术后,巷道下沉较大现象得到有效控制.

| Abstract: | Aiming at the influence of X4 collapse column residual stress during the 2101 belt roadway driving in Wulihou Coal Mine,the roof of the roadway is broken and subsided when the roadway is driven to 450-510 m.By analyzing the shortcomings of steel shed and anchor(cable)support in dealing with the support in the broken area,the paper puts forward the"grouting+anchor shed"combined support technology.After adopting combined support technology,the phenomenon of roadway sinking is effectively controlled. |
