Drilling
Abstract
In bench blasting the boreholes are drilled parallel to the free face against which the breakage can take place. In tunnelling, however, the only free face available is that of the tunnel face. Drilling parallel to a free face is consequently not possible. To achieve satisfactory blasting results an opening or void — the cut — must therefore first be created into which the surrounding rock can be blasted.
