1. A rock burst hazard prediction method based on seismic wave energy attenuation characteristics of a mine earthquake cluster, comprising predicting a rock burst hazard through the seismic wave energy attenuation characteristics of the mine earthquake cluster by comprehensively considering static load and dynamic load effects of seismic waves of the mine earthquake cluster; wherein
the rock burst hazard prediction method comprises the following steps:
constructing a static load strength index based on the seismic wave energy attenuation characteristics of the mine earthquake cluster by considering a cumulative damage effect of mine earthquake seismic waves on coal-rock masses;
constructing a dynamic load strength index based on the energy attenuation characteristics of the mine earthquake cluster by considering an energy accumulation effect of the mine earthquake seismic waves; and
determining weights of the static load strength index and the dynamic load strength index using a mean square error method, and further constructing a comprehensive prediction index by superposing the static load strength index and the dynamic load strength index to predict the rock burst hazard.
