| 摘 要： | 针对深部巷道开挖后易失稳、难维护等特点，基于巷道基本地质概况，分析了围岩控制技术路线，主要包括提高围岩强度和减小围岩应力，研究了“四高”锚杆支护技术、锚架联合加固技术、注浆加固技术等围岩稳定性控制技术，并结合巷道围岩分级类别进行了巷道支护。研究为类似工程条件下巷道支护提供了借鉴。

| Abstract: | In view of the characteristics of deep tunnels that are easy to lose stability and difficult to maintain after excavation，based on the basic geological overview of the roadway，this paper analyzed the control technology route of surrounding rock，which mainly includes improving the surrounding rock strength and reducing the surrounding rock stress，and studied the surrounding rock stability control technologies，such as "four high" bolt supporting technology，anchor frame joint reinforcement technology，grouting reinforcement technology，and so on.Combined with the surrounding rock classification of roadway，the roadway supporting was also carried out.The study has provided a reference for roadway supporting with similar engineering conditions. |
