Abstract：In order to solve the tuck net problem in deep roadway with compound roof, research was made on it by taking 1306 preparatory working in Anju Mine as an example. In this paper, starting from the increase of the support strength and the surface-protection ability, the rational and effective roadway support parameters and roof grouting measures were put forwarded through theoretical analysis and numerical simulation and according to the actual geological conditions of the surrounding rock. The field construction verified that the optimized supporting method successfully solved the problem of the deformation failure of the compound roof tuck net and guaranteed the security and stability of roadway support, meanwhile, it provided a reference for the support of other preparatory workings in this mine.
