Abstract: Through the knowledge of section form forming during working and application condition of bucket-wheel excavator, form of bucket-wheel excavator at working face of dass of open-pit mine and the parameters are analyzed. Meanwhile, the application of bucket-wheel excavator on an open-pit mine at the present stage is discussed. Especially, it is focusing on theoretical analysis of parameters of its end working face and its application discussion.

Key words: Bucket-wheel excavator, Working face, Parameter
