Energy Efficiency in Rock Blasting Semantic Scholar

Ten production blasts and one single-hole 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 blasted rock
