Three-dimensional geological modeling in mining area and its geomechanical applications

Three-dimensional geological modeling in mining areas and its corresponding spatial analysis have become a hotspot in mine geographic information system. In this paper, we build ARTPN (Analogical Right Triangular Prism Network) geological models based on the corresponding relations between plane graphs and sections in mining area, using geological hole and electronic peephole data. We also take Changcun coal mine as an example to achieve dynamic query of geostress and rock strength in 3D geological model, which provide reliable parameter for the original design of roadway supporting.
