Analysis on Support Plan of Roadway Excavation Construction

The safe and effective underground tunneling operation is the key prerequisite for the efficient development of mine production.It is essential for improving the overall efficiency of mine production that ensuring the effectiveness of the roadway in the tunneling operation face passing through special areas such as the roof broken zone.Combining with the actual project,this paper proposed a targeted segmented support plan for the roadway excavation construction,and made targeted research on the design of the support plan in different areas.The results show that the designed scheme has achieved effective control of surrounding rock deformation,which provides a solid guarantee for the safe development and the effective acquisition of comprehensive benefits of mine production.
