Abstract: GPSGSM is the core of Management System of Geology and Surveying in Underground Mine, with the goal of automatic processing of graphic data, computer aided mapping and its dynamic modification. It will be realized by this system that automatic deducing the boundary line of ore bed by means of AI technique, producing and modifying maps of Geologyand Surveying in Mine, providing all technical information for daily management of Geology and surveying and calculating ore reserves.This paper introduces its general design, structure and functions, technique of realization and application, etc.
