Rock burst assessment and prediction by dynamic and static stress analysis based on micro-seismic monitoring

Blasting technology is widely used to prevent coal bursts by presplitting the overburden in underground coal mines. The control of blasting intensity is important in achieving the optimal pre-split effectiveness and reducing the damage to roadway structures that are subjected to blasting vibrations. As a critical parameter to measure the blasting intensity, the peak particle velocity (PPV) of vibration induced by blasting, should be accurately...
