Electric mining vehicles have a new charging solution
Vedrana Spudic from ABB reports that an automated charger for electric mining trucks is enhancing operational efficiency.
In modern mining environments, vast underground networks bring people in close proximity to heavy machinery. Movements are coordinated and swift, with potential hazards around every corner. But, in a place where there are already automations and remote operations at scale, how do we replace some of the last human tasks?
The industry is close to fully autonomous work – removing people from the danger zones, increasing safety and building up sustainability. This article will focus on one innovative technology that comes from ABB’s research and development departments, with subsequent collaboration and testing with mining industry partners.
From concept to reality
Currently undergoing a programme of cold and hot weather testing in Sweden and soon in USA, ABB’s Technology Demonstrator eMine Robot Automated Connection Device (Robot ACD) is a new power charging solution for mining trucks.
Robot ACD, designed by ABB in collaboration with the industry, including Swedish mining company Boliden, and mining machinery manufacturer Komatsu, automatically connects and charges electric mining trucks without human intervention.
As the name suggests, Robot ACD comes from R&D activity under the company’s eMine approach that combines technologies for electrification, automation and digitalisation in mining with a focus on decarbonising heavy vehicle fleets, which currently account for more than a third of emissions in a mine.
When charging a domestic electric vehicle, the driver would ordinarily be required to step out, move around the vehicle and manually plug in their electric connection. However, in the mining location, it is necessary to have many adaptations, for example, being ruggedised to withstand harsh environmental conditions, and automated to ensure safety – complete with sensors and vision systems for precision and efficiency.
Safety as the mainstay
Automating processes and individual activities in the mine have become standard over the last decades, but manual interventions remain. One of the most important aspects of the Robot ACD is the impact it will have on workforce safety.
Mining has always been dangerous, but there are increasing ways to mitigate risks and remove people from the frontline altogether. With Robot ACD’s powerful, interoperable robotic arm, vision system and accurate sensors, the technology is compatible with megawatt charging system/ruggedised megawatt charging system (MCS/R-MCS) and quick charging connector (QCC) pin types, automating the connection and charging process. The Robot ACD enables personnel to stay in the safety of the haulage truck cabin, while the high-power charging process takes place.
The industry is on a trajectory towards automated and autonomous operations. Technologies like eMine Robot ACD are essential for applications that meet new needs and grow possibilities.
Sustainability in action
The Robot ACD is a key component of ABB’s eMine initiative, which aims to electrify the mining industry and reduce its environmental footprint. Electric mining trucks, charged in the field by the Robot ACD and the associated eMine FastCharge system, will produce significantly lower emissions compared to their diesel-driven counterparts. This shift reduces greenhouse gas emissions and improves air quality in mining areas, benefiting both workers and surrounding communities.
Moreover, electric equipment generates less heat and noise, creating a more comfortable work environment. The reduction in diesel particulate matter and other pollutants leads to better health outcomes for workers, who are no longer exposed to harmful emissions. Mining teams, including with mining company Boliden, have shared their comments on the cleaner, quieter and safer working environment.
Future operations and benefits
The transition to electric mining equipment, facilitated by technologies like the Robot ACD, also bring substantial economic benefits. According to McKinsey & Company, an all-electric mine can reduce operational costs, as electric equipment can cut energy costs by 40 to 70% and maintenance costs by approximately 30%. This is because there are fewer moving parts and less wear and tear than in traditional diesel machinery. These savings translate into more efficient and cost-effective mining operations, allowing companies to invest in further innovations and improvements.
Additionally, the Robot ACD’s interoperability ensures compatibility with various electric mining trucks and charging systems, including anticipated future technologies. This flexibility enhances the overall efficiency of mining operations, as different equipment can work together seamlessly. Trucks can be charged during scheduled breaks or downtime, minimising disruptions and maximising productivity.
In conclusion, ABB’s Robot ACD can enhance safety, promote sustainability and bring economic benefits. Reduced emissions mean improved air quality, and, of course, benefits from the steady supply of minerals and metals needed for modern lifestyles and energy transition over the long term.
