Modeling And 3D Visualization Of Coal Mine Water Inrush Channel Evolution

With the development of information technology in coal field,in order to realizing coal mine water disaster prevention and improving production efficiency,strata model building,formation processing and visualizing of water inrush channel must be studied.In this thesis,the database was created through the extraction of coal mine data.Study the modeling method of strata based on stratigraphic structure and geological data,visualizing the formation process of water inrush channel combined with the visualization technology of Unity3 D,and finally develop Water Inrush Channel's Three-dimensional Visualization System(WICTV).The main work of this thesis is as follows:(1)Analyze and process geological data according to the characteristics of geological data,use MySQL to build the geodatabase.(2)For the Mesh access structure of the three-dimensional model,combining with Unity3 D,use the data point interpolation algorithm of triangular mesh construction method to model the top and bottom of the strata,use the inverse distance weight interpolation method to interpolate the stratigraphic plate model and make strata fluctuation more natural,then connect the top and bottom of the strata to form the strata model,and finally combine the various strata to form geological model.(3)Study and analyze the evolution law of the formation process of water inrush channel,establish a spatial grids of coal mine of lower three zones according to the stratigraphic model,then build a percolation model of water inrush channel based on spatial grids.(4)Finally,we use Unity3 D engine and Visual Studio 2012 integrated development environment and C# language to program,design and implement a three-dimensional visualization prototype system of water inrush channel.
