Marble rock composed of calcium-magnesium carbonate. With the high pressure and heat rock recrystallized. Marble is a calcium-rich rock, so can take good polish. Often Marble can occur in metamorphic rocks. Metamorphic rocks can be mica schists, phyllites, gneisses, and granulites. Some marbles can consist of Lime or magnesia silicates minerals.
Rock explosives are limited due to danger of breaking the rock. Making cuts is an easy way of splitting.
Marble quarrying is the multistage process by which marble rock is extracted from the quarry ground. For easy extricating marble from quarry blast processed. Blasting process with explosive material processed through blasting compressors machines. After this process, rock leaves the quarry floor. Blasting process needs for easy mining. Extracting block through wire saw:
Marble is hard stone, hence it needs extracting through wire saw, chain saw or diamond wire saw. In this process, chain saw or wire saw leaves cut between the blocks. This machine can perform both vertical and horizontal cuts. Both dry and wet cutting also can be done. In wire saw, after setting the segment rope, as per as cutting requirement segment rope adjust with rail. Water puts into segment rope. Control speed of cut through the panel. In chain saw, first rail sets where cut to be done. Machine sets into rail. Machine starts according to cut.
Creating space between blocks:
Air pressure bag is used for create space between blocks after cut the blocks from the quarry. . It creates very strong core force to blocks; by force stone blocks get separate. Security is very crucial phase while using air pressure bag. Transporting Blocks:
After quarrying the blocks, the back hoe loader and excavator lifting equipments used for transporting the blocks.
Mobile and stable cranes are used for lifting and loading the blocks.
