Dimension stone quarrying involves extracting rough blocks and slabs of granite, limestone, marble, sandstone, or slate from open-pit or underground sites using heavy equipment, diamond wire saws, channeling machines, and in some cases controlled blasting. Workers operate in environments with significant slope, rock-fall, equipment, and dust exposure. Stone may be rough-cut on-site before shipment to fabricators or end users.
