Numerical investigation on damage effect of deep hole pre-cracking roof rock and controlling rockburst
Abstract Deep hole pre-cracking blasting (DHPB) technology is the preferred means of preventing and controlling rockburst induced by hard-thick rock layers in coal mines. When DHPB is applied to hard-thick rock layers, the insufficient knowledge about the crack extension scale under different rock p...
