| Abstract: | Taking working Face 205 of Huarun Coal Corp as an example,the geological mechanics of 3# coal seam was analyzed to find out the type 3 middle stability for surrounding rocks and the supporting mode for cuts.Theorefical calculation results,along with FLAC-3D numerical simulation,proposed resonable cut support technology solutions for 3# coal seam on the basis of analysis on surrounding rock yield destruction and the relative movement of roof,floor and two side walls,which provides some practical guide for face cut support. |
