The first step in granite mining is identifying areas with high-quality granite deposits. Geologists assess the potential quarry sites using geological surveys, core sampling, and testing the rock for color, pattern, and structural integrity.
Once a suitable site is identified, the process involves drilling holes in a specific pattern using a slotter. These holes are essential for the next step, as they help define the blocks of granite that will be extracted.
A wire saw is then used to cut through the granite, following the pattern of drilled holes. The wire saw uses a diamond-coated wire to make precise cuts, separating large blocks of granite from the quarry face.
Further drilling is done to create more defined blocks and to facilitate the insertion of wedges and shims, which are used to split the granite along natural fissures and pre-drilled lines.
After the blocks are separated, excavators are used to lift and move the granite blocks. This step involves careful handling to avoid damaging the granite.
The large blocks of granite are then transported to a processing facility where they are cut into smaller, more manageable sizes according to the requirements of the market or the specific project.
Finally, the sized granite blocks are dispatched to customers or further processing facilities. This involves packaging and arranging for transportation, ensuring the blocks are delivered in optimal condition.
Rig Driller: Used for drilling holes for initial assessment and during the extraction process.
Slotter: Used for drilling precise holes in a pattern to facilitate the use of the wire saw.
Wire Saw: Utilized for cutting through the granite to separate large blocks from the quarry face.
High Pressure Compressor: Provides the necessary air pressure for drilling and other pneumatic tools.
Jack Hammers: Used for drilling holes and breaking rock during the extraction process.
Excavators: Employed to lift and move granite blocks.
Loaders: Used for loading granite blocks onto transport vehicles.
Tippers :Used for transporting the granite blocks from the quarry to the processing facility or dispatch point.
