| 摘 要： | 采用预应力锚索加固支护深部高应力影响变形巷道与螺纹钢等强锚杆支护体系相比较,两帮位移速度和顶底板移近速度均明显降低,顶板离层量远小于离层临界值,说明巷道围岩已基本趋于稳定,支护方式完全可行,经济效益十分明显。

| Abstract: | Prestressed cable reinforcement is used to support deformed roadway impacted by deep high stress.Compared with rock bolting support system like screw-thread steel,both displacement velocity and advancing velocity of roof and floor are obviously decreased,and the size of roof is far less than critical value.The result showed that surrounding rocks are basically stable,the supporting method is completely feasible,and the economic benefit is very obvious. |
