摘　　要：煤矿开采面临的煤岩冲击危险直接影响矿井的安全高效生产和工人的生命安全,对现有巷道锚杆支护系统的抗冲击能力提出了更高的要求。以济三煤矿183下05工作面胶运巷为工程背景,结合工作面回采过程中微震监测结果及防冲措施等,采用动静载能量平衡原理和围岩体能量衰减特征相关理论,对不同顶板条件下胶运巷的初始支护强度开展了抗冲击能力分析,并提出了冲击地压巷道支护方案的优化建议,可为类似冲击地压巷道围岩安全稳定控制提供了借鉴和参考。With the increasing complexity of mining conditions in recent years,the coal and rock burst risk faced by coal mining directly affects the safe and efficient production of mines and workers'life safety,which puts forward higher requirements for the anti-burst ability of the roadway bolt support system.This paper took the belt conveyor haulage roadway of 183 low 05 working face as the engineering background,combining the micro-seismic monitoring results and the prevention measures in the process of mining and so on,and using the related theory of action principle of energy balance and rock energy attenuation characteristics,the anti-burst ability of the initial supporting intensity with different roof conditions in the belt conveyor haulage roadway were analyzed,the optimization suggestion of support scheme for coal and rock burst roadway was put forward,which can provide reference for surrounding rock safety and stability control in similar rock burst roadway.
