Nornickel has implemented a programme to modernise and upgrade the fleet of mining equipment. The company has purchased unique samples of battery equipment for pilot testing in the conditions of the Zapolyarny mine, the first in Russia.
The Zapolyarny mine (Bear Ruchey LLC, part of the Norilsk Nickel Group) has received two new self-propelled battery-powered vehicles – Utimec MF 500 SD (for transporting concrete mix) and Utimec MF 205 PER SD (for transporting people). The machines of the Finnish manufacturer of mining equipment, the Normet company, arrived in Norilsk in full factory readiness.
The Utimec MF 500 SD Underground Concrete Mixer is environmentally friendly, productive, and the best in its size class. It has a high-power output and a top speed of up to 20 km/h. The all-electric architecture includes the latest lithium-ion battery technology for fast charging and two powerful direct-drive electric motors. The batteries are also recharged while driving downhill and braking, further improving overall performance.
The Utimec MF 205 PER SD bus is designed for the safe transportation of personnel through underground mine workings. Fully reversible all-wheel drive with high traction and instant torque ensures safe and confident driving in difficult road conditions. The new ergonomic FOPS and ROPS compliant cab offers excellent visibility and comfortable driver and passenger compartments. The capacity of the battery bus is 20 people, as well as two people in the operator’s cab.
When fully loaded and moving up the slope, the charge of the bus is enough for 10 km, the concrete mixer for 8 km. Batteries will be charged at stationary posts. It takes 40 min. to fully charge. In addition, the set includes mobile chargers with a capacity of 40 kW for recharging at temporary sludge points. There is also a charging option from a common power supply. The main advantage of such equipment is the absence of harmful emissions into the atmosphere, which is an important condition in the limited space of the mine.
Representatives of Normet from Finland conducted theoretical and practical training for the operators of the Zapolyarny mine on pre-trip inspection and operation of battery machines. Now the equipment is undergoing pilot tests in a mine. The tests will take place within six months, their task is to evaluate how the equipment behaves in difficult Arctic conditions.
