Abstract: With the gradual depletion of shallow phosphorus resources， phosphorus mining enterprises turn to deep mining gradually.However，the rockburst phenomenon in deep phosphorus mining is prominent，which causes serious security risks to underground personnel and equipment.In this paper，taking the rockburst characteristics in the deep mining of a phosphate mine as an example， combined with the engineering excavation environment and excavation conditions，the concept of "synergetic mining" is introduced to study the rockburst prevention and control of deep phosphate mine from the perspective of stress transfer， stress prevention and control and improvement of lithology. The results show that:①the rockburst in underground mainly includes the immediate rockburst near the face of the opening roadway， the lag rockburst at the intersection of the roadway and the middle and upper part of the pillar in the mining area； ②by adopting the method of "pin" shape dislocation arrangement and active protection of pressure relief hanging net near the face of cutting roadway in the stope， the intensity and frequency of rock burst can be effectively reduced， and the splash debris produced by rock burst can be blocked；③by optimizing the size of the mining area， choosing the method of interval dislocation mining， optimizing the mining technology， and filling the mining area， the stress concentration degree of the mining area caused by excavation can be effectively reduced， so as to reduce the potential safety hazard of the operation site while controlling the engineering cost. Based on the concept of "synergetic mining"，this study puts forward the idea of rock burst prevention and control of deep phosphate rock， which can provide certain reference for ensuring safe and efficient mining of deep phosphate mine.
