The traditional mining industry confronts several challenges, including a hazardous working environment, a labor shortage, and efficiency bottlenecks. Recent advances in au tonomous driving offer promising solutions to enhance efficiency and sustainability in the mining transportation process. Specifi cally, High-Definition (HD) maps play a pivotal role in enabling autonomous driving by providing reliable environmental prior. Notably, mining areas lack conventional road signage, feature un structured road terrain, and exhibit semi-dynamically changing landscapes, which pose distinctive problems compared to urban environments. This paper proposes an HD map representation specially designed for surface mines, outlines a comprehensive workflow tailored to the unique challenges of surface mines, discusses the potential applications and reinforces the proposal with a case study in real mines. In contrast to much existing research, this work focuses on practical HD map applications in mines.
