| Abstract: | According to the geological characteristics of surrounding rock and its damage character in 42 mining area of Peigou Coal Mine,the original problems existed in U-type steel shed were analyzed,surrounding rock deformation characteristic using three kinds of supporting forms were also analysed comparatively using numerical simulation software FLAC.It was proposed that the scheme of coupling supporting with U-type steel shed and cable anchor should be adopted under the current geological conditions.The implementation of this proposal has obtained good effect. |
