%X Due to big plastic deformation of rock under high geostress, roadway deformation and failure characteristics of deep soft rock roadway are complex, and stability control of the roadway becomes very difficult. In light of this, it is important to choose proper support method for the roadway. Xingcun coal mine, with similar geological storage, is taken as research background. According to theoretical analysis and numerical analysis of support, based on the finite difference software FLAC<sup>3D</sup>, we systematically study the influence of support parameters on rock deformation, stress distribution and plastic zone distribution. The results show that, as for the soft crushed rock roadway, composite support method is superior to traditional method with single support .We can effectively control roadway deformation and obtain obvious support effect by using the composite method. Finally, the research can be reference for deformation control of soft crushed rock roadway in similar projects.
