Abstract: In this paper,according to the microseismic monitoring information in a deep mine,the principle of seismology was adopted to make a quantization calculation of microseismic parameters,combined with the rock burst records in underground,the response pattern between the ground pressure activities and temporal-spatial variation of microseismic parameters was further studied.The results show that the spatial variation of microseismic parameters in a time domain reflects the stress distribution in rock mass,which can provide basis to identify the rock burst danger areas.The temporal variation of parameters in a certain area is closely related with the rock failure process,and the abnormal changes of microseismic parameters with time such as sharp increasing,quickly decreasing can characterize the different deformation stages of rock mass.Based on the research results,the point at which the seismic hardening process of rock mass ends and the strain softening process begins can be used as the pre-warning point of rock burst.Finally,a general prediction model for rock burst in the mine is constructed,and has shown good effects in practice,which also provides reference significance for rock burst prediction in similar mines.
