Abstract: Aiming at the steering problems under special geological conditions in Anjialing Open-pit Mine, it summarized the basic type of steering mode in mining area of open-pit mine, and analyzed the characteristics of the various steering modes. Combined with the actual situation, it analyzed the influence factors of open-pit mine steering mode selection. According to the specific conditions in Anjialing Open-pit Mine, it selected seven indicators to establish evaluation index system, and made a comprehensive evaluation for steering problem with the ideal solution. Finally, it drew a conclusion that the L steering mode was most reasonable, which provided a decision-making basis for the site engineering design and production management.
