First, holes are drilled in the earth and explosives are placed inside. The explosives are detonated to provide the smallest release of energy for the most efficient blast. The entire blasting process occurs in just a few seconds. Larger quarries may blast once a day and smaller quarries may blast once or .

or shot rock is then excavated and loaded onto trucks that either feed portable crushers or stationary crushers for further processing. The explosive costs represent one of the biggest energy expenses in stone crushing, ranging from 30 to 40% of the total annual energy costs (Figure 1). Therefore, optimizing the

This finding indicates that if the kinetic energy carried by flying fragments can be utilized in further fragmentation, the energy efficiency in rock fragmentation will be largely increased. Then in different experiments it was found that higher loading rates were less efficient in rock fracture and fragmentation,,, . These investigations imply that the kinetic energy during rock fracture might be one of important .

Ten production blasts and one singlehole confined blast were monitored in two quarries in order to assess the measurable forms in which the energy delivered by the explosive is transformed in rock blasting. The seismic wave energy, the kinetic energy, and the fracture energy transferred in the blasting process were determined using the seismic field from seismograph records, the initial velocity of the .
