| description | In view of problems of simple indicator selection, big calculation error, complicated testing process existed in current bolt support design methods, stability classification of surrounding rock of roadway was determined by field investigation and laboratory mechanical test taking rail haulage roadway of No.3 north wing quasi mining area coal seam in a coal mine as research background, and different support schemes were put forward. Supporting effect of different support schemes were analyzed through numerical simulation analysis, and conclusions were obtained that supporting method of 'anchor cable + anchor bolt + anchor net + steel strip' is the most reasonable supporting scheme of all, it has the minimum scope of plastic deformation of roadway surrounding rock, roof and floor of roadway and displacement of two side coal-walls are the minimum. The field test results also indicated that the surrounding rock deformation is small, the supporting control effect is better when use the supporting method of 'anchor cable + anchor bolt + anchor net + steel strip'. |
