松散破碎煤层巷道掘进支护分析

Analysis on Roadway Excavation Support of Loosely Broken Coal Seam

以松散破碎煤层巷道掘进支护为对象开展研究,结合具体工程实际,在分析巷道掘进支护难点的基础上,提出有针对性的支护优化改良方案,并对其应用效果进行了探究。结果表明,改良后的方案实现了对围岩的有效控制,提升了掘进支护作业的有效性和安全性。

The study on the roadway excavation support of loose broken coal seam was carried out.Combining with the actual engineering practice,based on the analysis of the difficult in roadway excavation support,this paper proposed the targeted improvement optimization scheme and explored its application effect.The results showed that the improved scheme achieved effective control of the surrounding rock and improved the effectiveness and safety of the tunneling support operation.
