| 摘 要： | 分析沿空留巷巷内支护存在的问题，从提高巷道围岩自身强度及巷内支护对顶板支撑力出发，提出了沿空留巷巷内采用锚杆支护技术。工程应用表明，锚杆支护巷道沿空留巷，有效切落了采空区侧顶板，减小了巷旁支护体载荷；沿空留巷维护效果表明，该技术在留巷期间有效控制了巷道变形，提高了沿空留巷围岩整体稳定性。 |
| 关 键 词： | 沿空留巷 锚杆支护 巷旁支护 切顶 |

| Abstract: | The paper analyzed the problems existing in the support system of gob-side entry retaining. From the surrounding rock self strength of the mining gateway and the support to the roof support forces, the paper proposed the gob-side entry retaining to use bolt sup- port technology. The project application cases showed that the gob-side entry retaining with bolt support could effectively cut the side roof of the gob-sides and reduce the loading of the support devices. The maintenance results of the gob-side entry showed that the technology could effectively control the gateway deformation during the gob-side entry retaining and could improve the stability of the surrounding rock of the gob-side entry retaining. |
| Keywords: | gob-side entry retaining bolt support support of gateway side roof cutting |
