Abstract
The workings required for the development of underground mines include shafts, drifts/crosscuts and stope or gallery openings. Computer modelling of such a system demands a full visualisation of the ore body model and mine openings in a single drawing. Researchers in the field must possess a suitable mathematical background and be conversant with computer graphics techniques in order to develop mine design systems. In this paper, a simple and practical approach to the design of underground mine openings, and the modelling and visualisation of orebodies has been developed which presents a useful methodology for any mine designer. The Drawing eXchange Format has been employed to allow the design process to be reduced to geometric calculations. The mathematical model used in the system provides the ore body model and development plan for underground mining, with shafts, drifts, stopes, etc. The application of the DXF format is discussed along with the application of the C++ language to a practical example. In order to visualise ore body and mine plans, any drawing editor capable of processing the DXF format can be used, and mine planners can prepare their own visual mine design system using the approach described.
