Abstract: In order to solve the difficult problem of controlling surrounding rock including large deformation，strong rheological property，strong floor heave in soft-rock roadway with high stress in deep mine，by surveying deformation and failure characteristic of main roadway at -980m level in Xingdong Colliery，its deformation mechanism under the environment of high geo-stress，strong tectonic and high seepage pressure was discussed.Applying Coulomb-Mohr stress circle，failure action of high principal stress difference on surrounding rock induced by excavation of main roadway was analyzed.On the basis of this，combined supporting projection of“anchored mesh injecting + high-strength anchored cable + grouting reinforcement”was put forward.Engineering practice showed that this technology could effectively solve the supporting problem of -980m main roadway and had reference value for similar condition.
