Abstract In order to study the precursor characteristics of rock burst induced by deep excavation of the underground powerhouse at Huanggou pumped storage power station in Heilongjiang province，microseismic(MS) and electromagnetic radiation(EMR) monitoring methods are comprehensively applied to identify the micro-fracturing of the surrounding rock. By analyzing the temporal and spatial distribution law of the microseismicity and electromagnetic radiation activity in the monitoring range，the precursory information of the induced fractures and the correlation between the both monitoring results，the results show that：(1) The microseismic events are characterized by the regional clustering in space and some clustering positions are highly consistent with the zones where rock burst happened during the initial excavation，revealing the local stress in a continual readjustment process. There is a positive correlation between the frequency of microseismic events and the intensity of external disturbance in corresponding time intervals. The sharp decline of the energy index(EI) and the explosive growth of the cumulative apparent volume(CAV) generally indicates the occurrence of rock burst or large-scale rock rupture events. (2) In the fault fissure zone of the underground powerhouse，the significant change of electromagnetic radiation intensity indicates that rock burst or large-scale rupture will soon happen. The distribution of the peak electromagnetic radiation pulse number is consistent with the migration direction of the local stress field，as well the adjustment time of the local stress field is about 8 days. (3) The spatial distribution of surrounding rock fracture revealed by the two monitoring methods is consistent，and the precursor time resulted from electromagnetic radiation method is slightly earlier. There is a good correlation between the both results of the local stress field in the event source region，and the distribution of the peak electromagnetic radiation pulse number is in full accord with the migration of the apparent stress. The engineering practice shows that the comprehensive monitoring method is effective for the identification of the precursor information about rock rupture in the underground caverns. It can provide the foundation for further research of rock burst monitoring and early warning based on the monitoring results. The research is very important for the safe construction of the hydropower engineering.

Key words： hydraulic engineering rock burst microseismic monitoring electromagnetic radiation(EMR) precursory information correlation
