With the SKS-1 mine Norilsk Nickel plans to open up deeper ore deposits and therefore entrusted SIEMAG TECBERG with deliveries for, at approx. 2,000 m, Russia’s deepest mine.
The SKS-1 mine thus beats other Russian mines by approx. 500 m. In earlier years SIEMAG TECBERG already supplied and commissioned a large number of installations to Norilsk Nickel Besides the shaft depth, this project posed a further challenge, as it was required to deliver a complete shaft hoisting system as a complete system with a specified annual hoisting performance. Production is planned for 12 operating hours a day on 330 days of the year and will be carried out with a double-drum BLAIR winder with skip/skip hoisting system (drive output of 8,000 kW) for running speeds of up to 14 m/s and a maximum payload of 30 t. In the service shaft operates a 4-rope KOEPE winder as a cage/counterweight system that, with a drive output of 2,250 kW, moves payloads of up to 20 t at up to 12 m/s. Alongside these two winders SIEMAG TECBERG delivered further equipment such as braking systems, its own-developed sliding bearings, rope sheaves, hydraulic compensation rope sheaves, complete loading and unloading equipment and rope-changing equipment.
Altogether, for this order SIEMAG TECBERG has transported approx. 3,000 t of equipment and material to the mine site in Norilsk and began with the installation in summer 2018.
