An advanced geo-information system for mining applications

Resource evaluation and mine design involve large amounts and differing types of spatial information. Efficient integration and handling of such information requires advanced geometric modeling techniques and data organizations. General purpose computer-aided design, and computer graphics systems are not designed to deal with such complexity. This paper presents efficient approaches to handle geo-information in order to facilitate mine design and planning. Particular emphasis is given to spatial information. The octree scheme is introduced as it is used to represent highly irregular ore bodies. A prototype system, which has been developed as a result of this research, is also introduced. The system facilitates geometric operations, and also spatial and attribute queries which are essential to mine design. An example of the practical utility of the system is also presented.
