Blasting Methods in Mining and Quarrying – GRT review
Bench blasting is a common technique used in open-pit mines. It is blasting in a vertical or sub-vertical hole or a row of holes towards a free vertical surface. More than one row of holes can be blasted in the same round. A time delay in the detonation between the rows creates new free surfaces for each row.
