Support method and parameter selection for roadside packing gob-side entry retaining in Yushutian Coal Mine
This article introduced the technology of using ultra-high water filling material to fill the roadway side and gob-side entry re-taining support in the No.110403 working face of Yushutian Coal Mine.Based on production conditions and roadway support conditions,the layout and size of the roadway side filling body were determined,and methods and measures for strengthening support of the filling body and retaining roadway were proposed.Support parameters were selected,and the deformation of the surrounding rock was predicted through numerical simulation,which has provided technical support for roadside packing and gob-side entry retaining for the transporta-tion roadway.
