Abstract: Against the backdrop of the national “dual carbon” goals and green mining construction strategy, the mining industry is facing an urgent need for green and intelligent transformation. Traditional hydraulic excavator, with the low energy efficiency, high carbon emissions, and issues related to oil pollution and leakage, has become the key bottleneck restricting the green minging development. Focusing on the fully electric controlled intelligent excavator, this systematic elaboration highlights its core role in advancing mining greening. The analysis covers the technological shift from hydraulic to fully electric drive in the power system and the resulting improvements in energy efficiency and zero exhaust emissions. Further exploration is conducted on health-status diagnosis and predictive maintenance systems for key components based on multi-source data fusion and intelligent algorithms, which contribute to reducing resource consumption and waste generation. Intelligent operation decision-making methods tailored to complex mining conditions are also investigated to achieve systematic energy conservation and emission reduction. The findings demonstrate that by deeply integrating electrification and intelligent technologies, the fully electric-controlled intelligent excavator not only enhances equipment energy efficiency and reduces carbon emissions but also promotes a shift in mining production models toward high-quality development, which is characterized by green and low-carbon practices, reduced human involvement, and intelligent operations, thereby providing core equipment support for sustainable mining development.
