Research On Visual Mining Technology Based On 3D Geological Body

The three-dimensional visualization model of geological structures can represent complex geological conditions and the shape of geological bodies in three dimensions.It can be effectively applied to various fields such as mineral resources exploration,oil and gas exploration and development,coal field geological exploration,mine production and management,and geological disaster management.In the early stage,based on a large number of valuable drilling,geological,geophysical and geochemical data collected in a certain area,the three-dimensional geological model of the area was successfully constructed and visually displayed,and a three-dimensional geological body model construction and display system was developed.The constructed three-dimensional geological model contains a large amount of data.The three-dimensional geological body only realizes the visualization of these data,but the application of these data is not well implemented.Based on the IBM SPSS Modeler data mining platform,we have successfully developed a marine geological data mining and analysis application system to realize the mining and analysis of marine geological data.Based on this,the paper integrates the above two systems,and uses the ocean geological data mining and analysis application system to realize the visual data mining in the three-dimensional geological body,and realizes the visualization in the form of visual civil construction.The main work is as follows:(1)Research and analysis of three-dimensional geological body model construction and display system.For the analysis of the system function module,the visualization function of the three-dimensional geological body model is mainly analyzed.At the same time,the data types and data structures in the three-dimensional geological body and the data format derived from the model are studied,and the data types required for mining are determined.(2)Research and analysis of marine geological data mining and analysis application systems.It mainly analyzes the data mining algorithms and functional modules included in the system,and also determines the input data format requirements of the system.(3)Research on data transmission methods between systems.Based on the previous studies of the two systems,and based on the study of data transmission methods among various systems,the data sharing method was determined,so as to realize the communication between the three-dimensional geological body model construction and display system and the marine geological data mining and analysis application system.(4)The integration of the three-dimensional geological body model construction and display system with the marine geological data mining and analysis application system was successfully realized.The visualization mining based on three-dimensional geological volume is realized,and the data mining analysis results are displayed in the form of visual maps or tables.
