The Golconda diamondiferous region is located in the Southern Indian peninsular shield, [2] which was formed during the process of proterozoic and Insular India. [3] The region is spread over 50,000 km 2 (19,000 sq mi), within the sediments of the Krishna-Pennar river basin and Deccan Traps, [2] and contains 120 out of the 150 kimberlite pipes in India. [4]
Yellow ground kimberlite is easy to break apart and was the first source of diamonds to be mined. Blue ground kimberlite needs to be run through rock crushers to extract the diamonds. [27] Mir mine. See also Mir Mine and Udachnaya pipe, both in the Sakha Republic, Siberia. The blue and yellow ground were both prolific producers of diamonds.
Exploration diamond drilling differs from other geological drilling (such as Reverse Circulation (RC) Drilling [3]) in that a solid core is extracted from depth, for examination on the surface. The key technology of the diamond drill is the actual diamond bit itself. [4] It is composed of industrial diamonds set into a soft metallic matrix.
