Influence of Hole Arrangement on the Section of Cavity Formed by Cutting Blast

Influence of Hole Arrangement on the Section of Cavity Formed by Cutting Blast

In order to optimize the arrangement of cutting holes in tunnel blast in Dahongshan Copper Mine, theoretical analysis and numerical simulation were combined to preliminarily determine the diameter of the hollow hole and the distance between the charge hole and the hollow hole during cut blast, which...
