| 摘 要： | 由于受深部复杂高应力作用，姚桥煤矿中央采区大巷多次严重破坏，针对此情况，在地应力实测基础上，分析地应力与巷道稳定性的关系及破坏原因，提出了注锚加固和锚喷注支护结构，根据实测应力状态与数值模拟计算结果，科学、合理、经济地确定了支护参数.工程实践表明：基于地应力实测，采用注锚加固为核心的联合支护结构，有效地解决了深部高应力下破碎岩巷的支护问题.

| Abstract: | The main tunnels of central mining area were seriously destroyed several times due to complicated high stress and deepness in Yaoqiao Coal Mine.Aimed at this problem,the relationship between ground stress and tunnel stability,damage reasons were analyzed based on results of ground stress obtained in situ.The grouting and bolting reinforce technology and the support structure of grouting and bolting with concrete layer were put forward to solve this problem.The concerned support parameters were scientificall... |
