The second place was taken by two projects, one of which was presented by employees of Alrosa and the other by the Yakutniproalmaz Institute. The third place was awarded to a project by five authors representing several organisations.
“It is possible to resume mining at the Mir mine only after the creation of a security pillar to prevent the ingress of brines from the Meteger-Ichersky Water-Bearing Complex into the existing mine workings system. This is due to the fact that a significant portion of workings has been performed with halogen-carbonate rocks,” he explains.
“Our next task is to bring together the most successful technical solutions in order to propose a single concept for the resumption of mining operations based thereon,” says Cherepnov, adding that the concept will be presented at the All-Russian Conference later in April.
Alrosa will pay one-million rubles to each team whose projecttook the second place. The third place will be rewarded with 500 000 rubles. The authors of the remaining seven projectsthat came through to the final round will receive incentive awards in the amount of 100 000 rubles.
Most applications for the competition, which Alrosa launched in January, came from Russian cities, including Moscow, Yekaterinburg, Krasnoyarsk, Novosibirsk, Irkutsk and Yakutsk. One proposal came from South Africa.
