Abstract In order to study the propagation attenuation law of vibration wave produced by rockburst in surrounding rocks of roadway and the surrounding rocks response characteristics，a numerical model is built by FLAC3D software based on propagation effects analytical model. The vibration source is loaded in the model，and the monitoring points of vibration wave produced by rockburst are emplaced in designated position. The model is analog calculated through dynamic analysis module，and the spectrum characteristics of vibration signals collected by monitoring points are analyzed with MATLAB software. Then vibration wave propagation effects produced by rockburst in surrounding rocks of roadway can be further studied. Results show that：(1) The power attenuation relationship between vibration wave produced by rockburst and focal distance is found along roadway. Vibration wave decays rapidly at the short distances while it decays slowly at longer distances. (2) Vibration wave energy produced by rockburst on roof is the maximum. Vibration influence on shoulders is smaller and minimum on sides and floor. These conclusions provide certain theoretical foundation on further research of vibration wave produced by rockburst propagation law and roadway destructive characters.

Key words： mining engineering rock roadway rockburst vibration wave produced by rockburst propagation attenuation law surrounding rock response characteristics spectrum characteristics
