Influence of Charge Hole Spacing on the Crack Propagation Behavior under the Effect of Empty-Hole Directional Blasting
In order to explore the reasonable spacing of charge holes in empty-hole directional blasting, based on the action mechanism of empty-hole directional blasting, the influence of charge hole spacing on crack propagation is studied, the calculation formula of charge hole spacing is deduced, and the bl...
