The collaboration between the three companies has enabled heavy transportation with electric driven battery vehicles. In tandem with reducing carbon emissions, the electrification of mining also promises improved health and safety for the industry’s workforce. By deploying this system, the collaboration partners aim to prove that the underground working environment can be significantly improved, with less emissions, noise and vibration while reducing the total cost per ton.
Each partner has provided a unique set of expertise to this development process, clearly demonstrating the value of industry collaboration. Epiroc has added dynamic charging to its proven battery-electric Minetruck MT42 SG and battery system, and the trolley solution is equipped with ABB’s DC converter, HES880 inverters and AMXE motors to enhance the power. The truck features a trolley pantograph connected to an overhead catenary line, a concept which is highly suitable for long haul ramps. The electric trolley line gives additional assistance to the battery-electric mine truck on the most demanding stretches up-ramp while fully loaded, enabling further reach and battery regeneration during drift, which increases productivity drastically for a mining operation.
ABB created the infrastructure from grid to wheel, including the electric trolley truck system design and the rectifier substation for the test track. The definition of standards and vehicle interface was jointly developed by the project partners. The eMine™ Trolley System also integrates with the distributed control system (DCS) ABB Ability™ System 800xA® to monitor the electrical system.
