Mining crushed stone is more involved because the deposits are consolidated, meaning solid rock formations. The most common types of crushed stone come from deposits of limestone, dolomite and granite. To produce crushed stone, the massive formation first is drilled with a pattern of holes loaded with explosives by a licensed blaster.

To investigate energy dissipation and particle size distribution of rock under dynamic loads, a series of dynamic compression tests of granite specimens were conducted using a conventional split-Hopkinson pressure bar (SHPB) device with a high-speed camera. The experimental results show that the dissipated energy increases linearly with an increasing incident energy, following two different
