Automatic drawing of the geologic profile of an underground mine based on COMGIS

This paper introduces a method of building a prototype system of geologic profile auto-drawing. A .NET development platform and integrated environment was used along with a component based design, a B/S system model, and XML techniques. Knowledge rules for creating geologic profiles and generating virtual drilling data from existing bore data and expert, hand-drawn geologic profiles were acquired. Then a prototype system was established by utilizing the known knowledge rules, topological relationships, and semantic relationships among strata. This system has a friendly human–computer interface and can meet requirements of mutual queries between attribute and spatial data. The generated profile map is editable. This study provides a new powerful tool for underground mine work.
