摘要
分析了巷道支护技术方案,将支护方案应用到采煤工程实践中,对巷道的变形情况以及锚杆载荷变化情况进行了连续30 d的监测,监测发现,大断面巷道支护技术的应用取得了理想的效果,该支护方案能够达到预期目标,可以确保巷道掘进过程的安全。
This paper analyzes the technical scheme of roadway support, applies it to the practice of coal mining engineering, monitors the deformation of roadway and the change of bolt load for 30 days continuously, and finds that the supporting technology of large section roadway has achieved ideal effect. The support scheme can achieve the expected goal and ensure the safety of roadway excavation process.
