GIS BASED INFORMATION MANAGEMENT AND ANALYZING SYSTEM FOR GROUND SURFACE MOVEMENT AT MINES

In accordance with engineering practice of Jinchuan Nickel Mine in Gansu Province, China, this paper studies the method and process of developing ground surface movement information management and analyzing system for mines. The system is a GIS based secondary development. The paper discusses the structure and functions of the system. The system contains three modules: management of ground surface movement information, analysis and evaluation of ground surface movement, and ground surface movement forecast. The system makes the best of powerful information management and spatial analyzing capabilities of GIS, and can carry out the analysis and evaluation of ground surface movement by combining Surfer 8.0. And in the module of forecast, using the technique of MATLAB 6.5 program with VB 6.0, the system can achieve the ANN prediction model for GPS monitoring data. The study results shall improve management and analyzing efficiency for ground surface movement information in Jinchuan Nickel Mine, and can be used in developing the information system of ground surface movement in other mines.
