巷道交叉点修复工艺研究与实践

Research on Repairing Technology of Roadway Intersection and Practice

在抬棚上方采用风镐掘进的施工工艺进行失修巷道交叉点处理,并利用成熟的锚梁网索联合支护技术进行参数设计。经实践和后续的巷道变形观测及支护效果监测结果可知,此种施工工艺和支护技术从经济与安全的角度看是可行的,比传统的替换抬棚修护具有显著的优点。

Using the pneumatic picks tunneling to conduct bad repaired roadway intersection treatment above the timber supporting,and using mature technology of Roof Bolting with bar and wire mesh to conduct parameter design,this construction technology and supporting technology is feasible from the point of view of economy and security,through the practice and results of follow-up the roadway deformation monitoring as well as supporting effect monitoring,and it has significant advantages compared with traditional displacement maintenance of timber supporting.
