The Russian diamond mining group PJSC ALROSA, which holds a leading position in the world in terms of diamond production, has started drilling 84 wells for the construction of the Mir-Deep mine in the Mirny district of Yakutia. This was reported by the company's press service.
Employees of the enterprise will drill 42 wells on the skip shaft and 42 wells on the cage shaft section with a depth of 550 m. Then, a refrigerant will be supplied to them, which will create an ice-rock curtain, which will prevent the penetration of groundwater from the aquifer. This will ensure the safety of the mine builders.
ALROSA-Spetsburenie performs drilling of so-called "glasses" to a depth of 0 to 50 meters. The second stage is drilling to a depth of 50 to 550 meters. We must complete the work in the first quarter of 2025.
At the end of 2023, PJSC ALROSA began preparatory work for the construction of the Mir-Deep underground mine. The diamond reserves in this area are estimated at 173.5 million carats, and their extraction will begin in 2032.
