摘要

井下巷道的严重变形不仅会威胁生产作业安全,还会产生高昂的维护成本,对矿井生产作业安全造成严重影响。结合具体工程实际,在分析巷道大变形现状和开展围岩大变形松动圈测试的基础上,提出有针对性的巷道联合支护方案,并对其支护效果做出分析。结果表明,所设计的联合支护方案实现了对巷道围岩稳定性的有效控制,为生产安全提供了有力保障。
        The serious deformation of underground roadway not only threatens the safety of production operation, but also produces high maintenance cost, which has a serious impact on the safety of mine production operation. Combining with the concrete engineering practice, based on the analysis of the present situation of large roadway deformation and the test of large deformation loosening zone of surrounding rock, this paper put forward a targeted roadway joint support scheme and made an analysis of its support effect. The results show that the joint support scheme can effectively control the stability of surrounding rock of roadway and provide a strong guarantee for production safety.
