掘进巷道过断层探究

Discussion on Roadway Excavation Passing through Fault

断层作为井下常见的地质构造形式,对巷道掘进作业的安全性有显著影响,以此为出发点,对掘进巷道过断层的施工支护方案展开探究。结合A矿具体工程实例,对其过断层的联合支护方案展开具体阐述并分析有关实践效果,实践表明该联合支护技术是一种有效的掘进巷道过断层工艺,具有良好的推广空间。

As a common underground geological structure form, fault significantly affects the safety of roadway excavation work, with which as a starting point, this paper discusses the supporting scheme of roadway excavation passing through fault. Combined with the project case of A Mine, the combined support program for passing through fault is specifically addressed, and the practical effect is analyzed. The practice shows that the combined supporting technology is an effective technique for roadway excavation passing through fault, which is of good promotion space.
