Abstract
3D geological modeling technology is a key area in the development of intelligent mining, as well as an important branch of scientific computing visualization. This technology utilizes data collected from geological exploration and engineering design to create a 3D model, and displays underground rock layers, topography, structures and other 3D features on a 2D plane to achieve intuitive expressiveness. This paper mainly analyzes drilling data and explores two main directions: surface and solid modeling in 3D geological modeling. The general Kriging algorithm and irregular triangulated network (TIN) method are used to construct the reservoir surface. Then, the grade modeling in volumetric modeling is done by using the tetrahedral element model (TEN), thus changing the current situation where only average grade is given. Finally, after analyzing and exploring the public drilling data, this paper applies ideas build a 3D orebody model and obtain the exact grade distribution in the orebody using the TEN model.
