摘　　要：基于大同煤田火成岩侵入区域巷道围岩裂隙发育、煤层整体承载能力差、锚杆和锚索等支护构件锚固性失效问题,以永定庄矿5502回风巷火成岩侵入为工程背景,拟定采用普通锚索封孔注浆技术方案。新方案实施后,通过围岩监测,锚注支护后围岩完整性明显提高,围岩变形程度明显小于未锚注区域,且未出现脱锚和锚索拉断现象,保证了永定庄矿火成岩侵入区巷道的安全稳定。In view of the surrounding rock fracture development,poor overall bearing capacity of coal seam,the failure of anchorage performance of support components such as bolt and anchor cable in the igneous-rock invaded area of 5502 ventilation roadway in Yongdingzhuang Colliery,the author proposes the sealing grouting technology with ordinary anchor cable,whose implementation shows that the integrity of surrounding rock has increased remarkably in bolt-grouting area with less surrounding rock deformation than non bolt-grouting area and no anchor trip and tensile failure of anchor cable,guaranteeing the safety and stability of roadway in the igneous-rock invaded area.
