This paper first analyzes five kinds of steering transition modes and compares the specific characteristics of these steering modes. Considering the actual production status of a surface mine, SMCAD, a computer-aided-design platform, is used for 3D geological modeling to study the mining. The advantages and disadvantages of four kinds of continuous steering transition modes are compared, and the variation of stripping ratio, transient time, load distance and total cost for each transition mode are revealed. Finally, a right angle turn left ditch optimal program is determined as the optimal scheme. This research achievement has a guiding significance for practical production in surface coal mine., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null,

为平台进行三维地质建模、实体算量、模拟开采，引入垂直权高差概念，对比了4 种连续式转向过渡方式的优劣，揭示了各转向方式条件下的剥采比、过渡时间、运距和总费用等变化规律，综合确定留沟直角转向为最优方案。, correspAuthors=null, authorNote=白润才，教授，研究方向为露天开采技术与理论、数字矿山，电子信箱：licsaass@163.com,
