基于IDL的三维地质矿产建模

三维地质建模具有形象、直观、便捷、易操作等优点,可以缩短地质研究的周期,提高研究效率,在地质、矿产、地下施工等方面有突出的贡献。本文运用IDL语言建立了三维地质矿产可视化模型,通过建立可视化的界面对地质体实现移动、缩放、旋转操作,以及做地质剖面、水平切面动画、矿产评估、采矿后沉降分析等功能,清晰地展示了地质体内部的各个细节,突出了三维地质矿产建模在地质解译、灾害模拟、矿产评估等方面的应用价值。

3D geology and mineral modeling based on IDL

3D geological modeling is intuitive,convenient and easy to operate.It can shorten the cycle of geological study,improve the efficiency of geological study and contribute much to the fields of geology,mineral and underground construction.IDL(Interactive Data Language) as an ideal software tool for multidimensional data visualization analysis and application,has many advantages for the 3D visualization of various geological information.In this paper it proposed a 3D visualization model of geology and mineral resources by IDL,and realized the functions of moving,zooming and rotating process of the geological model by way of establishing a visual interface.Moreover,some other functions were also realized,such as geological model slicing,horizontal section animation,mineral evaluation and settlement analysis after mining.Using all these functions above,the details of geological model were shown vividly and the value of geology and mineral modeling on the aspects of geological interpretation,disaster simulation and mineral evaluation were verified,which is important to mining of mineral resources and later geological disaster simulation.
