A consortium consisting of the Siemens Industry Solutions Division and Siemag M Tec² GmbH, Netphen, has received an order from Mining Technology S.I.M., Zurich, to supply two new shaft winding installations for the Skalisty mine in Russia. The final customer is MMC Norilsk Nickel.
The machines are intended for use in the new VS-10 shaft which is to be sunk and are scheduled to start operating at the end of 2010. Thyssen Schachtbau GmbH, Muelheim (Germany), is the general contractor with responsibility for equipping the new shaft and providing the associated infrastructure installations. The order volume for Siemens amounts to more than ten million euros.
The Norilsk Nickel group is the world's leading producer of palladium and nickel as well as being an important supplier of platinum and copper. Its mining activities are concentrated on the Kola peninsula and in the Taimyr region of Siberia, the “Polar Division” of Norilsk, where the Skalisty mine is located.
For the new shaft winding installations, Siemens will be supplying the power distribution equipment, the automation technology with safety systems, the cooling and ventilation systems for the motors and a package of spare parts. Siemens will also be responsible for engineering, supervision of the installation work and commissioning. The mechanical components will be supplied by Siemag M-Tec². The shaft winding installations consist of drum-type hoisting machines and will initially be used to sink the new shaft, which, when completed, will be 2000 meters deep. Directly following this, the machines will be converted in preparation for their final use as a cage winder and skip winder.
One of the two machines will be used during shaft sinking as a kibble winder and will later be converted into a cage machine with a counterweight. Due to its drive output of 2900 kilowatts at 27.2 rpm., this machine will achieve a hoisting speed of eight meters per second. The second machine will be used for emergencies during shaft sinking and will be converted into a skip machine with a counterweight after the initial work has been completed. Its drive output will be 1430 kilowatts at 27.2 rpm. The hoisting speed will also be eight meters per second.
Commissioning for sinking the shaft is scheduled for the end of 2010, and final commissioning is to be carried out in 2015. From then on, the cage machine will be used for carrying miners and materials on five levels between 980 and 1810 meters deep. The skip machine will transport 85 metric tons of ore per hour from the loading station at a depth of 1089 meters, and 60 tons per hour from the loading station at 1810 meters.
