摘 要:本文将xx煤矿巷道掘进支护情况作为分析对象,在对巷道原支护进行分析的基础上,得出原支护方案最大的弊端是巷道顶板出现了较大的离层变形问题。针对该问题及巷道支护需求采用理论分析和现场勘察的方式,重点对锚杆设置的数量、锚索布置的方式进行了优化,有效提升了巷道围岩支护的稳定性,相对于原巷道支护方案取得了更好的支护效果,巷道围岩稳定性增加明显,为煤矿井下开采提供了更为可靠的安全环境。This article takes the excavation and support situation of xx coal mine roadway as the analysis object.Based on the analysis of the original support of the roadway,it is concluded that the biggest drawback of the original support plan is that there is a significant deformation prob-lem of the roadway roof.In response to this issue and the demand for tunnel support,theoretical analysis and on-site investigation were adopted,with a focus on optimizing the number of anchor bolts and the arrangement of anchor cables.This effectively improved the stability of tunnel surrounding rock support,achieving better support effects compared to the original tunnel support plan.The stability of tunnel surrounding rock increased signifi-cantly,providing a more reliable and safe environment for underground coal mining.
