| The measurable forms in which the energy delivered by the explosive is transformed in rock blasting is assessed. 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 blasted rock face obtained from high-speed video footages, and the fragment size distributions from image analysis of the muckpile material, respectively. The maximum total energy measured accounts for not more than 26% of the available explosive energy, if this is rated as the heat of explosion, though lower figures are usually obtained. The values measured for each of the energy components range from 2-6% of the total energy available for the fragmentation energy, 1-3% for the seismic energy and 3-21% for the kinetic energy. For the confined shot-hole, the seismic energy was 9% of the heat of explosion. | |
