Research on mining subsidence prediction based on GIS

Based on a GIS (geographic information system) and stochastic approach, a study has been done for predicting the mining subsidence of Beiminghe Iron Mine. A three-dimensional (3D) calculating model related to geographic, geologic and inherent information has been made, and then the new system, which is developed by the stochastic and component techniques, is used to predict the mining subsidence. By using the effective spatial analytical function and the drawing tool of GIS, the analysis results intuitively show the degree and scope of mining subsidence. By a comparison with the observation data of the ground surface and actual situation, the proposed approach has been verified and a 3D visual platform is offered for safety control of the metal mine.
