Abstract 1209 mining face of Wanfeng Mine was taken as example, FLAC3D finite difference computing software was adopted, damage scope and features of roof surrounding rock were analyzed to settle reasonable roadway support parameters. The result showed that the current support parameters cannot meet the needs of controlling deformation of surrounding rock, surrounding rock shaping area of roadway exceeded the length of anchor bolt support, the result provided reference for support parameter design of compound roof roadway.
