研究矿井深部掘进锚杆支护技术的主要目的是提高深部掘进作业的安全性。本文首先对锚杆支护的作用进行梳理，并分析影响煤矿巷道围岩稳定的决定性因素，证实需要根据巷道类型的不同选择合理的锚杆支护技术措施，从根本上保障巷道掘进施工的安全性，降低因围岩结构不稳定问题所引发的巷道施工安全事故问题，这是保障矿井开采安全的关键技术手段。“,”The main purpose of studying bolt support technology for deep excavation in mines is to improve the safety of deep excavation.In this paper, the function of bolt support is sorted out first, and the decisive factors affecting the stability of surrounding rocks of coal mine tunnel are analyzed. It is proved that reasonable bolt support technical measures need to be selected according to different tunnel types to fundamentally guarantee the safety of roadway excavation and reduce the safety accident of roadway construction caused by unstable surrounding rock structure.This is the key technical means to guarantee the safety of mine mining.
