摘　　要：针对21307工作面厚煤层顶板采用锚杆支护所面临的锚索破断、顶板离层量大的问题,在对工作面地质水文、煤岩等条件分析的基础上,初步设计工作面的支护方案,并基于FLAC3D软件对方案进行优选,最终根据经济性和安全性因素确定最佳支护方案。最后,通过现场观测验证了长锚索与短锚索联合支护方案对顶板围岩的控制效果。Based on the analysis of the geological and hydrological conditions of the working face and coal rocks,the preliminary design of the support scheme for the working face was based on the analysis of the working face geology and coal rocks,and the optimization of the scheme based on FLAC3D sofware.Finally,the effectiveness of the combined long and short anchor cables on the control of the roof surrounding rock was verified through field observation.
