| Abstract: | According to poor integrality of overlaying rock in Beiminghe Iron Mine,China,a research was done for predicting the subsidence of metal mines based on geographic information system(GIS) and probability-integral method.A three-dimensional(3D) calculating model related to geographic,geologic and inherent information was built.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. |

| Keywords: | metal mine sublevel caving method without sill pillar mining subsidence prediction geographic information system(GIS) surface deformation probability-integral method |
