The following methods used for quarrying blasting. Digging and Excavating: This is applicable for soft stones occurring in small blocks, Instruments like Pick Axes, Shovels, Chisel are used in this method. Heating: If the rocks occur in layers and if the surface is heated by fire, differential expansion separates the upper layer from the lower layer.
The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones. It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging below the ground, sometimes at considerable depth.
