Design of 3D Virtual Mine Based on 3D GIS Technology

It is necessary to construct simulation system for special subsystems of mining, tunneling, electromechanical equipment, transportation and ventilation of whole mine, 3D virtual mine, in order to realize whole mine’s integration of "monitoring,controlling and management". The paper put forward a design scheme of 3D virtual mine based on 3D GIS technology and full automation of coal mine. It briefly introduced the key technology of 3D GIS, and introduced the design of software structure, system’s function and database of the 3D virtual mine system in details. The system can reflect the status of environment, equipment and personal and has practical analysis function for the special subsystems, so it can make departments of production management and safety supervision know production status and accident cause of mine directly, rapidly and generally, and provide decision-making criterion of dispatch and command for personal of mine production management. The system is a basal information platform in coal mine, and it can provide data interface for higher management software and expert system of coal mine. The system will greatly enhance the safety level of coal mine and provide basal service for "digital mine".
