· What is the Quarrying of Stones? Quarrying can be described as the process where the stones are taken out of the natural rocks to carry out different types of engineering purposes. It is done at ground level in an exposed condition, for which an appropriate site has to be selected that can be effectively used for the desired purposes.

· Stone carving, a key process in creating sculptures, involves quarrying marble, shaping it, and refining it with various tools. Michelangelo, a famous sculptor, sourced his marble from Carrara, Italy. He visualized his sculptures as figures trapped within the marble, waiting to be freed. This process is labor-intensive, meticulous, and requires

· The first step in marble quarrying is to take down the primary block. Primary Block is a large dimensioned chunk of rock loosened from the quarry wall. This is most often achieved by drilling, blasting or/or sawing. A primary block can vary in size. It size depends on the stone type up to 1000 cubic meters and 2700 tons.
