ALROSA is planning to hold an open competition for design solutions to form a concept of resumption of diamond mining at Mir deposit. The decision was announced in follow-up the research and technology seminar in Yakutniproalmaz Institute. The participants also outlined three focus areas for the development of technical solutions to ensure the safety of underground mining operations at the deposit.

The seminar was attended by 70 specialists from structural subdivisions, including Mirny Mine Construction Trust engaged in the construction of underground mines, Mirny and Udachny Mining and Processing Divisions, Vilyuiskaya and Mirny Exploration Expeditions, Yakutniproalmaz Institute, and NTC NOVOTEK. Former ALROSA’s specialists who have extensive experience and are well acquainted with the problems of underground construction and mining attended the seminar.

Experts presented 16 reports with more than 30 possible approaches and options for the resumption of mining at the deposit. During the discussion of reports and speeches, the seminar participants outlined three major directions of further development of technical and technological approaches to the safe resumption of mining at the deposit. The first of them provides for the restoration of existing openings (shafts) and pit bottom roadways ensuring the maximum possible use of the existing surface complex infrastructure. The second approach involves the construction of new shafts to the full depth of explored reserves, with the priority mining of deep levels and simultaneous creation of an integrated drainage system from the deposit through a drainage shaft and dewatering wells. The third approach provides for the cutback of walls of Mir open-pit mine to ensure the access to its bottom and create effective water pumping with subsequent underground mining.

For a detailed and comprehensive study of approaches to solving the problem of resumption of mining and preparation of the final technical design, ALROSA is planning to hold an open competition for design solutions, expecting to engage a wide range of specialized organizations, scientists and experts. The competition will reveal the best technical solution or a set of solutions to be applied while developing the concept of resumption of mining at Mir deposit. This concept will form the basis of the technological regulations and technical design for the safe and cost-effective development of the deposit reserves.

ALROSA President Sergey Ivanov:
– Our core task is to ensure the complete safety of operations at Mir deposit, therefore we need a perfect design solution. We will get involved the entire leading scientific community, both Russian and international experts, in the development of the underground mine restoration project. We expect to receive the vision of the future project in the III quarter of next year.
