摘　　要：为解决综采工作面支护参数与工作面地质、煤层条件不符导致对围岩控制效果不佳,继而引发生产事故的问题,在对工作面地质、煤层条件分析的基础上,基于FLAC3D软件建立数值模拟仿真模型,重点对锚杆长度、预应力和间距等锚杆参数对巷道围岩附加应力的影响进行仿真分析,最终得出最佳的锚杆支护参数。In order to solve the problem that the support parameters of the comprehensive mining face do not match with the geological and coal seam conditions of the face,which leads to poor control of the surrounding rock and then causes production accidents,based on the analysis of the geological and coal seam conditions of the face,the numerical simulation simulation model was established based on the FLAC3D software,and the impact of anchor parameters such as the anchor length,prestressing force and spacing on the additional stresses on the surrounding rock of the roadway were analysed,and the optimal anchor support parameters were finally obtained.The best anchor support parameters are obtained.
