Efficient wall control blast designs should achieve safe and stable slopes while obtaining the required fragmentation. The goal of wall control blasting is to make the transition from well-fragmented rock within the blast to an undamaged slope in as short a distance as possible. Wall control blasting is a process of continuous improvement using near-field vibration measurements and modelling.

12/10/2012 Rock fragmentation by blasting is achieved by dynamic loading introduced into the rock mass. The explosive loading of rock can be separated into two phases, the shock wave and gas pressure phase (Fig.2). Fig. 2 the detonation process, the quicker the energy release from explosives mass, in the form of a shockwave followed by gas pressure, is applied to the borehole wall. In other words ...
