Abstract: Based on completely analysis of failure mechanism of broken soft roadway in suntuan coal mine,the corresponding control methods were discovered, as a result, the scientific supporting measures and dynamic supporting technology characting frame-shotcrete-grouting complex reinforcement were put forward,and then supporting parameters and construction process were optimized. Engineering practice shows that the supporting methods can better control deformation of the broken soft roadway, achieved good technical and economic benefits, it is referential significance for control and maintenance of roadway in the similar conditions.
