Heating method. This method is used for quarrying of granite stone. In this method fuel is burn on surface of rock. Due to uneven temperature layer of stone separate or break. As result of this broken pieces of stone brake into small desires shape. That day we broken stone by electrical thermal energy.

splitting techniques may be applied on most rock types, it is working best on hard siliceous (quartz-rich) ones. Partly because they in general display the most brittle behaviour, but also because it is a well documented fact (and experience among quarrymen) that siliceous rocks (granite in particular) have well defined preferred splitting

A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word quarry can also include the underground quarrying for stone, such as Bath stone
