Diamond projectile

"Diamonds of Anabar" and a young scientist from the NEFU produced a unique projectile for the study of diamondiferous rocks

Thanks to the cooperation between the diamond mining company and the university, a one-of-a-kind auger-core drill was manufactured so far. He fundamentally changes the way of studying placer deposits of diamonds.

Diamond projectile
Thanks to the cooperation between the diamond mining company and the university, a unique one-of-a-kind auger drill rig has been manufactured so far. It fundamentally changes the way we study alluvial diamond deposits. “We call the invention“ Screw-Column Drill ”. Because during its development the core pipe and auger are combined. The auger is needed to transport the destroyed rock to the accumulator. The core pipe plays the role of accumulator. During drilling, the bit destroys the bottomhole rock and the auger is transported to the top, ”says Nikolai Timofeev, a young scientist and senior lecturer at the Department of Technology and Technology of Exploration of Mineral Deposits at the NEFU Geological Survey. “Under our conditions, in the exploration of alluvial deposits, the punching works are carried out manually. That is, drilling with shells is not provided. etc. Such a method of studying the breed is quite dangerous and costly in terms of the rational use of time and human resources. With the help of our projectile it can be much more efficient and it is safer to conduct research. No explosions are needed. And the process is much faster in time. In addition, geologists are interested in having as many rocks as possible for research, because the more samples are taken, the better the test result. a sufficient amount of rock that allows geologists to efficiently and accurately determine the content of a useful component. " Most of the republic is in the conditions of permafrost, so the temperature factor adversely affects the process of building exploration wells. While drilling, the ice contained in the frozen rocks melts, turning into water . The demolished rock, climbing the auger, freezes to the instrument. "To overcome this factor, we provided a hatch in the core pipe, so that the adherent rock can be easily removed from the projectile.The production version of the projectile is 750 mm in diameter and two meters in length.It is located on the section" Majat "of the company" Almazy Anabar " ", Where they pass experimental tests," - says Nikolay. The screw-core drilling tool is a new invention. The novelty of the design of our drilling rig is confirmed by the patent of the Russian Federation. At the same time, the projectile needs improvement and elimination of shortcomings. "Experimental production tests will show which parts will need to be further developed and improved.We have created an initiative group consisting of teachers and students of our department.We will jointly analyze the action of the projectile and, in general, to study the process of drilling shurfosquares in permafrost conditions," - The young scientist shares. Nikolay Timofeev was born in the Amginsky district, in the village of Bolugur, in 1987 year. After graduation, he entered the NEFU, the geological survey department, the department of technology, technology and exploration of mineral deposits. In 2009 year after graduation I entered postgraduate study. And the problem of drilling large diameter bore holes in the conditions of the cryolithozone began to be dealt with under the scientific guidance of a professor with many years of experience in drilling wells Revo Scriabin. Participated in various competitions and conferences. In 2014, Nikolai took part in the republican contest "I am an engineer" for the prizes of member of the Federation Council Vyacheslav Shtyrov, where he took second place. "I had very serious rivals, they had good ideas and developments, so the competition was serious and intense.In general, I consider competitions among engineers very useful and stimulating to further achievements," Timofeev recalls.
