Based on geological model of deposits and by means of CAD method,the authors put forward the building method of layered opencast mining geological model, whose layers are composed of bench.

Three-dimensional ledges were observed on the broad faces and at the tip of bainitic plates, which proves the real existence of ledges.

The results show that all the initial bainites formed in different alloys at different temperatures are with three-dimensional ledges on the broad faces and/ or at the growth edges of α1 plates but without internal stacking faults, which proves that ledges exist generally on bainites in Cu-Zn-Al alloys and that the growth of bainites is govern.
