Oyu Tolgoi, one of the largest copper-gold mines in the world located in Mongolia, has received its first battery-powered mining vehicle for trials. The Normet Utimec MF100 Material SD is designed for bulk material transportation in underground mines and tunnels, with a 10-tonne payload capacity and a fast charging capability.
The fast-charging vehicle also has two high-torque direct drive electric motors, energy recuperation technology, and efficient hydraulic dual-circuit oil immersed multi-disc brakes. The vehicle has a front axle suspension system, improving safety, driving comfort, and increasing component lifetime. The batteries get charged when the model during movement downhill and deacceleration, leading to better efficiency.
The maximum speed of the Utimec is 20 km/h. It features a fully reversible 4WD with high traction capability and instant torque to ensure safe and sure movement in difficult ground conditions.
The machine is fully owned by Oyu Tolgoi and is the first of several equipment types to be trialled at the mine, including LHDs, drill rigs, and bolters. The machine will start operation in the coming months after workforce training and establishment of charging infrastructure.
Rio Tinto, which now has a 66% interest in Oyu Tolgoi LLC, the mine operating company, following its acquisition of Turquoise Hill Resources Ltd, is focusing on strengthening its relationship with the Government of Mongolia and moving the project forward with a simpler and more efficient ownership and governance structure.
The introduction of the battery-powered mining vehicle is a significant milestone for the underground operation and is said to be the result of collaboration between multiple teams.
