Core Viewpoint - The article highlights the emergence of "driverless + pure electric" mining trucks as a new trend in the mining industry, emphasizing their advantages in automation and environmental sustainability [1][6]. Group 1: Industry Trends - A series of new mining trucks have been launched this year, featuring a design without a driver's cabin and powered entirely by electricity, leading the trend of driverless operations in mines [1][6]. - The demand for mining trucks in China's open-pit coal mines remains around 30,000 units annually, with a shift towards electric/hybrid and intelligent solutions driven by policies, safety, environmental concerns, and new energy [5][6]. Group 2: Technological Advancements - The latest driverless mining trucks are equipped with large-capacity battery systems, such as a 564 kWh battery that can carry 90 tons for approximately 60 kilometers on a full charge, replacing 15,000 tons of diesel annually and reducing CO2 emissions by 48,000 tons [6]. - The design of driverless trucks eliminates the driver's cabin, allowing for increased battery capacity and advanced computational power, which enhances automation capabilities in complex mining environments [6][10]. Group 3: Performance and Efficiency - Electric mining trucks offer natural advantages in control response, with electric motors providing instantaneous torque output and seamless integration with autonomous systems, improving operational efficiency and safety [7][9]. - The integration of electric platforms with intelligent algorithms allows mining trucks to function as autonomous robots, capable of self-sensing, decision-making, and execution in challenging mining conditions [10]. Group 4: Challenges and Future Outlook - The industry faces challenges in developing larger-tonnage electric driverless trucks, particularly regarding battery performance, including energy density, power output, and safety, as increased weight can affect stability and payload capacity [11]. - The introduction of range-extended mining trucks has been noted, which combine electric and diesel power to enhance efficiency, with one model recovering 40,046.72 kWh of energy annually and achieving an 8.8% fuel savings rate [12].
