Granite
quarry is a pit or some open excavation from which granite is obtained.
To obtain granite from a quarry either digging, cutting or blasting
process is used. This process of obtaining the stone is called
quarrying. Once quarrying is done, the processing of granite starts. The
four operations that are involved in the processing of granite are:
- Dressing
- Cutting/ sawing
- Surface grinding and polishing and
- Edge-cutting-trimming.
Quarrying of granite in India is conducted in Rajasthan, Bangalore, Chickmaglur, Hassan, Kolar, Mysore, Mandhya Tumkur, Bellary Raichur districts and at many other locations.
There are very few quarries that have have mining machinery, such as compressors and drilling machines for drilling and blasting, cranes for lifting big blocks, and dampers and trucks for transport. Hence the mining and processing of the granite is done manually. Even the drilling and channeling are done by hand chisels and hammers.
