| Abstract: | By analysis of the roadway stress in high-stress zone by using FLAC;numerical simulation software at 1209 material inclined roadway, the paper makes a preliminary discussion on surrounding rock deformation influenced by mining and presents the transformation on support patterns-bolt-and-anchor support in roadway roof and bolting support fitting with channel-steel anchor at two sides, which can effectively control the surrounding rock deformation. |
