Abstract: A large coal field is usually divided into several mining areas in surface coal mine, therefore the steering transition problem between adjacent mining areas must be considered. 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.

Key words： surface coal mine SMCAD 3D geological modeling right vertical height steering mode
