Once the quarry and its processing plant reach the end of their life-cycle, further opportunities for CO2 neutralizing activities arise. The intended project outcome is to use the Energy Management model to generate EE opportunities and CO2 compensation activities to minimise the environmental impact created throughout the quarry life-cycle.
The process begins with a detailed three-dimensional survey of the quarry face. This allows the explosives engineer to desig n the blast and to plot where the shot holes should be drilled so that the
