Research On Mine 3D Integrated Information System And Its Application

As digital and information technology to speed up in China's mining industry, mining companies have had a large number of multi-source, heterogeneous and distribution three-dimensional information. At the same time there have been "more data-rich, the more knowledge-poor" situation, and it is in urgent need of the integration management to mine 3D spatial information and data mining in-depth research. To that end, this paper used the method of theoretical analysis and practical application to study mine 3D spatial information integrated system and its application. The main contents of the study are as follows:(1) Mine 3D information has an in-depth analysis. Mine spatial information is divided into three categories: raw information, results information and production information. After the information flow analysis among these three categories information, they come to each other's internal relations.(2) Mine 3D information has an in-depth data mining. According to the characters of the mine spatial information, using different data mining methods, to achieve the parameters of coal and rock, drilling data and measurements of data mining respectively. The information infrastructure is provided for the further application of information and spatial information mining model.(3) Spatial information for clustering in-depth study. According to the changes in the direction of spatial data can produce cluster, we provides a new spatial data clustering method based on direction, and design and implement direction clustering algorithm. The algorithm has been verified by experimental data. Application-specific requirements, gradient clustering is provided on the basis of direction clustering. The algorithm of gradient clustering has been successfully on the fault information clustering. It provides a new method for fault identification.(4) According to the mine spatial information characteristic, we have proposed the establishment of spatial information surface model based on constrained Delaunay triangulation(CDT); according to data layered characteristics of the coal seam, based on irregular tetrahedron, we establish mine spatial information solid model from the coal seam contour of discrete data. These methods provide a theoretical basis for spatial information integration model.(5) Mine 3D information integration. According to the lack of the single model of mine spatial information, We integrate the contour model, the CDT surface model and the irregular tetrahedron-based solid model, leading to the mine spatial information model integrated management. After the information flow analysis among raw information, results information, production information and spatial information model, come to all types of spatial information between internal relations. Mine 3D spatial information integration is realized.(6) The mine three-dimensional space information integration system has been designed and developed.
