摘　　要：为进一步保证综采工作面生产的安全性和高效性,以大断面切眼为研究对象,在对其水文、地质以及瓦斯等条件分析的基础上,对不同支护形式对比,得出采用锚杆+锚索联合支护方案,并通过数值计算得出使用该大断面切眼的三类支护方案;基于FLAC3D软件对三类支护方案进行对比,综合支护效果和支护成本、施工效率等因素得出最佳支护方案。In order to further ensure the safety and efficiency of the production of the comprehensive mining face,the large section cuthole is taken as an example,and based on the analysis of its hydrological,geological and gas conditions,different support forms are compared and a combined anchor rod+anchor cable support scheme is adopted.Finally,based on FLAC3D sofware,the above three types of support solutions were compared,and the best support solution was obtained by integrating the support effect,support cost and construction efficiency.
