Unmanned scraper is an important part of intelligent mine construction, in order to achieve unmanned underground mining in high-altitude and cold areas, this article summarizes the current development status of unmanned driving systems for scrapers both domestically and internationally .analyzes the relevant theories and key technologies of autonomous driving systems for scrapers, and summarizes them from the perspectives of trajectory deviation prediction technology for underground scrapers, autonomous driving multi deviation control technology, and collision prevention prediction and control technology. Taking Huatailong mine in Tibet as an example, the latest network communication technology 5G was used to build a 5G+scraper unmanned system. It is of great significance for the development of unmanned scraper systems in high-altitude and cold areas. [ABSTRACT FROM AUTHOR]
