3d Modeling And Application Of Gold Deposits In The Long Quanzhan Of Shan Dong Province Based On Sections

Three-dimensional modeling and visualization technology of the non-layered ore body is a hot topic in China and abroad. The establishment of gold deposit three-dimensional visualization system plays an important role in perfecting digital mine project, improving production efficiency and accelerating information construction of the mine.At first, the paper analyses the research situation and existent problems of the gold deposit in the Long Quanzhan area of the YiShu fault zone middle part in the Shan Dong province, puts forward the methods of building the three-dimensional solid model for the geological body including gold orebody, gold mineralized body and fault in the Long Quanzhan area, described the research significance, research thinking and the research contents of the three-dimensional solid modeling.Secondly, the paper depicts the development history of digital mine, analyses research situation of domestic and international mine three-dimensional visualization software and modeling methods, and summarizes existent problems and proposes relevant countermeasures , then , the paper studies the key technique and algorithm of gold deposits three-dimensional modeling and visualization system: puts forward the solid combined with volume modeling idea according to the ore body, studies the conception model, logical data model, modeling process in detail, expatiates some key technique such as OpenGL and so on.Thirdly, according to the situation of gold deposits industries, the paper presents the whole framework of gold deposits three-dimensional visualization system.On the basis of LRGIS and using Visual C++ 6.0 and OpenGL as developing tools, the paper realizes the three-dimensional visualization system professionally gold deposits-oriented and introduces design principles, developing environment, system structure, interface design, especially for the system functions in detail, further, introduces the algorithm realization of the systemfunctions and the characteristics of the system.At last, the paper introduces the metallogenic background of the Long Quanzhan area. On the basis of the three-dimensional modeling and visualization system, the paper built the solid models of the geological bodies including gold orebody, gold mineralized body and fault in the research area, the models present the spatial form and mutual relationship of the gold orebody, gold mineralized body and fault impersonally, reveals the characteristics of the mineralization alteration zone,discusses the control law of the fault structure to the spatial distribution, morphology, mineralized local concentration of the ore body. According to the ore body dislocation show combined with brittle shear zone in the research area from the stereomodel, the paper forecasts the deep ore body preliminarily, therefore, the good effect proves the application value for the three-dimensional modeling and visualization system.
