· Key Differences. Mining is the process of extracting ores, coal, precious stones, and metals from beneath the earth's surface. It often involves digging underground tunnels and shafts to reach these materials. On the other hand, quarrying is specifically the extraction of stone and other construction materials from open pits or quarries.

Quarrying is used mainly in the production of construction and building materials, such as solid stone or crushed rock for aggregates, or for raw materials for processes such as cement manufacture. As a technique, quarrying is normally only used where raw materials of adequate quality and size cannot be obtained economically by other means.

To begin quarrying, the top layer of organic soil is removed to expose the rock face. Next, quarry men outline blocks of stone according to the size needed with iron picks and drive metal wedges in with mallets to form cracks until the stone comes loose. An alternative technique was to force dried wooden wedges wrapped in cloth into the cracks

· 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.
