摘　　要：近距离煤层群回采巷道受重复采动影响,围岩支护困难。通过分析现有巷道支护状况,采用理论计算、数值模拟和工程实践等多种技术措施,通过调整锚杆、锚索间排距,对比分析不同支护方案下的巷道围岩应力分布规律和围岩位移,对巷道支护参数进行优化,确定了合理的支护方案,保障巷道围岩稳定。The extraction roadways in close-range coal seam groups are subject to repeated mining disturbanc⁃es,making surrounding rock support challenging.By analyzing the current roadway support conditions and em⁃ploying theoretical calculations,numerical simulations,and engineering practices,this study adjusts the spac⁃ing between bolts and cables,compares stress distribution and displacement of surrounding rock under differ⁃ent support schemes,and optimizes roadway support parameters,ultimately determining a reasonable support scheme to ensure the stability of the roadway surrounding rocks.
