Deformation prediction and 3D visualization model for rock mass of high underground water mining area

Based on the subsidence prediction model by probability integration, this paper proposed a new “superimposed model” which is made up by “3D-stratum” and “declining subsidence model”, the latter is formed when mechanical properties and stress states of the rock soil media are changed because of water layers' erosion which is happened in the high underground water mining area simultaneously with strong precipitation. Further more, the “similar tri-prism” model and “dummy borehole chain” are used to control the “layers”. And then a simulation experiment called “basin ponding” is designed to illustrate the retrieval significance of ture-3D visualization for mining subsidence of stratified ore-bodies constructed by the “superimposed model”, whose deformation datasets are set in a space coordinates information file which is self-programmed, besides the surface and inner geological structures are made a forward visualization analysis based on the achievements of predecessors.
