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.
