摘要

在实际的生产实践中,巷道支护设计大多采用经验法或工程类比法来完成,这种支护设计往往存在强度浪费、缺乏重点等问题,不能做到针对围岩稳定性特征的针对性支护。本文基于围岩稳定性分析,对巷道围岩进行分类,确定基础支护方案,针对不同类型巷道实现针对性支护,并将支护设计投入实践,检验支护效果。实践取得了良好效果,为围岩稳定性分类及支护设计提供参考。
        In the actual production practice, the roadway support design mostly uses the experience method or the engineering analogy method to complete, this kind of support design often has the strength waste, lacks the key question and so on, cannot achieve the goal support which aims at the surrounding rock stability characteristic. Based on the stability analysis of surrounding rock, this paper classifies the surrounding rock of roadway, determines the foundation support scheme, realizes the targeted support for different types of roadway, and puts the support design into practice to test the support effect. Practice has achieved good results, providing references for stability classification and support design of surrounding rock.
