摘　　要：为进一步提升回采巷道的支护效果,保证其对巷道围岩进行稳定控制,以2301工作面为研究对象,在对其顶底板条件分析的基础上,对煤岩力学参数进行测定,为后续模型准确构建奠定基础。基于FLAC3D软件分别对锚杆长度、间排距,锚固方式,锚索长度、间排距等指标进行优化设计,为今后工作面锚杆支护参数的优化设计提供思路。In order to further improve the support effect of the mining roadway and ensure its stable control of the surrounding rock of the roadway,take 2301 coal seam as an example,based on the analysis of its roof and floor conditions,the mechanical parameters of coal and rock were measured,laying the foundation for the accurate construction of the subsequent model.Based on the FLAC3D software,the parameters such as the length of anchor rods,the spacing between rows,the anchoring method,and the spacing between rows of anchor cables are optimized and designed,providing a simple and effective idea for the optimal design of anchor rod support parameters in future working faces.
