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.
