摘要
3维地学模拟 (3DGeoscienceModelling,简称 3DGM)与虚拟矿山系统 (VirtualMineSys tem ,简称VMS)是数字矿山 (DigitalMine ,简称DM)战略实施的关键技术 ,其中 3DGM是VMS及所有真 3维地学虚拟现实系统的基础。基于国内外VMS研究与应用分析 ,指出目前 2 .5维VMS的缺陷和不足 ;同时 ,对当前国际学术界 3DGM理论与方法进行了评析。进而 ,从 3DGM与VMS耦合的角度出发 ,提出了一种新的 3DGM方法 :类三棱柱 (AnalogicTri Prism ,简称ATP)法。ATP模型由点、TIN边、TIN面、棱边、侧面TIN和ATP体共 6组基本元素组成。本文设计了ATP的数据结构 ,并给出了基于实验钻孔的 3DGM可视化图。
D Geoscience Modelling (3 DGM) and Virtual Mine System (VMS) are the key technologies of the implementation of Digital Mine (DM), and 3 DGM is the fundament of VMS and all other true 3 D Geo-VR system. Based on the analysis to the present situation and application of international VMS, the shortcomings of 2.5 D VMS are pointed out; and, based on the review of the theories and methodologies of 3 DGM international, a new 3 DGM methodology, named as Analogic Tri-Prism (ATP) model, is provided for the coupling of 3 DGM and VMS. ATP is comprised of six groups of elements, which are points, TIN-sides, TIN-faces, edge-sides, edge-TINs and ATP-body. The data structure of ATP model is designed, and a 3 D visualization case based on experimental borehole data is shown.
