In order to improve the accuracy of rock burst monitoring，combined with the research results obtained in the field of fiber grating measurement, the fiber grating borehole stress meter and demodulation substation are used as the acquisition and demodulation of the multi-point mining stress data of the next hole in the coal mine, guided by stress control theory, the early warning system of rock burst was established based on the technique of mining stress monitoring, which collecte data by developed borehole stress meter, and demodulate data by fiber grating substation, and analyze data by the R&D mining stress system software.The study results showed that the system can be applied to the mining stress monitoring and dynamic pressure warning of coal mine working face, which can reveal the change of the working surface affected by mining dynamic stress accurately and derive the temporal and spatial evolution law of stress field.The system was added as a new method for prediction and early warning of mine rock burst disaster, thus effectively reducing occurrence of rock burst accidents.
