Study on influencing factors and prediction of peak particle velocity induced by roof pre-split blasting in underground
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....
