How are marble slabs mined without breaking?
Marble is metamorphised limestone and a soft rock, so care is needed to quarry large slabs with a minimum of breakage. The most common modern method of marble quarrying is bench mining, where a huge wall of marble is cut loose from the quarry sides using diamond cutters, saws and hot torches. Dirt is piled up beneath this wall in order to cushion the fall when it comes loose. Once it is free and falls, the slabs are cut from the rock wall using the same types of tools and hoisted from the bottom of the quarry. Broken pieces are often crushed and sold as decorative stone for drives and gardens, while larger slabs are shaped and polished into slabs for building or other uses.
