| 摘 要： | 以朱集矿埋深900 m首采工作面沿空留巷扩刷修复工程为背景，采用现场实测和理论分析的方法分析深井留巷扩刷修复前围岩变形、应力、结构等状态，提出留巷扩刷修复结构临近失稳的概念，确定留巷扩刷修复的合理时机，组织留巷扩刷修复时的合理工序，制定留巷扩刷修复巷道的主被动协同支护方案。研究结果成功运用于朱集矿深部留巷扩刷修复工程，围岩监测结果表明，留巷扰动变形在修复后得到有效控制，各项指标满足下一工作面回采要求。

| Abstract: | Based on the gob-side entry retaining reparation engineering of first coal mining face in Zhuji mine around 900 m underground，deformation，stress and structure state of roadway surrounding rock before reparation were analyzed by field measurement and theoretical method；the conception of“critical structure between instability and stability”of gob-side entry retaining reparation was proposed；reasonable repairing time and construction process were determined；initiative-passive collaborative supporting system was concluded. Research result was applied to the gob-side entry retaining reparation engineering in Zhuji mine successfully. The results of ground pressure monitoring show that the deformation of this repaired roadway is controlled effectively；and all indices satisfy the requirements of next mining face. |
