摘要
支护系统的安全性直接关系到井井下巷道掘进工作,至关重要。本文介绍了复杂地质条件下矿井掘进支护现状及常见问题分析,着重对矿井下巷道掘进支护的有效控制措施进行了阐述,促进巷道掘进工作质量的提升。
The safety of the support system is directly related to the underground roadway driving work is very important. This paper describes the analysis of complicated geological conditions of mine excavation and supporting the status quo and problems, focusing on the coal mine roadway excavation and supporting the effective control measures are introduced to promote the work to improve the quality of tunnel excavation.
