Abstract According to the supporting problem of large span and dynamic mining pressure roadway in the Dafosi colliery of Binchang Co. in Shaanxi Province，the deformation and failure characteristics of roadway in complex surrounding rocks are analyzed based on the special engineering geological conditions and affections of dynamic mining pressure；and the analysis results indicate that the main reasons of supporting failure are local tectonic stress，soft rock mass in floor，dynamic mining pressure and explosion shock loading. Taking the 40106 haulage roadway for example，a repair scheme considering the complementary control of cable anchor，strengthen monomer point column and angle bolt is determined and is applied to engineering practice on the integrative idea. The field observation results show that the floor heave and the roof crush of large span can be controlled effectively by decreasing the span of the roadway，strengthening roof and sides and increasing bolts in sidewalls and floor corner of roadway.

Key words： mining engineering large span dynamic mining pressure roadway floor heave
