摘要
在矿井开采工作中,开挖巷道是保证矿井安全的 1 个关键步骤.为了保障煤矿巷道掘进的安全性,对巷道支护工艺与矿井生产的特性进行了阐述,探讨了巷道支护工艺中存在的一些问题,并总结了其在复杂地质情况下的掘进与支护施工注意事项,提出了掘进巷道分次支护措施,并通过实践运用,证明了其支护效果良好,为类似工程的施工提供了参考.
Abstract
During the operation of a mine,roadway excavation is a crucial step to ensure mine safety.In order to ensure the safety of coal mine roadway excavation,the characteristics of roadway support technology and mine production were elaborated,and some problems in roadway support technology were analyzed.The key points of the precautions for excavation and support construction in complex geological conditions were summarized.The segmented support measure for excavation roadway s was proposed,and the application effect showed that the support effect was good,which can provide reference for similar projects.
