摘要
针对由于回采巷道围岩变形量增加而导致的围岩稳定性变差的问题,以西铭矿西部下组煤回风巷道为研究对象,在分析锚杆、锚索支护机理的基础上,对锚杆、锚索的关键参数进行设计计算。经计算,各项指标均满足回采要求,保障了巷道围岩的支护效果及质量。
Aiming at the problem of poor stability of the deformation of the surrounding rock of the mining roadway,the research object of the coal return tunnel in the west of the West Mingmu is the design and calculation of the key parameters of the anchor rod and the anchor cable on the basis of the analysis of the supporting mechanism of the anchor rod and the anchor cable.Through calculation,all the indexes meet the stoping requirements,and the supporting effect and quality of the surrounding rock of the tunnel are guaranteed.
