Abstract: The paper introduced the general design philosophy of the metal ore-body 3D modeling system, the characteristics of geological database, the design of table structure of geological database, and the main module functions in this system. The system well described various features on ore-body spatial extension under the three-dimensional conditions to indicate the ore grade distribution and the metallogenic rule and solve the reserves calculation problem. It provides an accurate, comprehensive and scientific basis for making decision for the design, production and management of mine.

Key words: Metal ore-body, 3D Modeling, System development
